Programming languages are necessary tools for teaching computer programming languages, so it is no surprise that deciding which one is the “right tool for the job” can be a contentious issue. To build solid foundations for such debates, we must first consider how different languages’ features relate to one another. Many Java programmers do not think about how to make their programs run faster. Application developers should tune their applications before putting them into production. Application code tuning often results in significant performance gains. The proposed model intended to assist Java programmers in fine-tuning and improving Java -based applications. This article review work in time, the time required to execute some algorithm, i.e., speed of operation, flexibility in modifying some code, and performance, are all factors in the comparison operation. To evaluate the program is better; the same code used to compare the two. in this review, researcher work in terms of the time compare in Java with other language, before compare other language, show performance Java in time and runtime Java, after select some language to compare with Java, like C language, C++ language, C# language and Python, to compare Java performance with other language and illustrate best execution time performance. Comparing Java with other languages reveals that the latest JDK runs faster and executes tasks more swiftly than older versions of Java JDK.

Programming is one of the most advanced and valuable skills increasingly adopted by students these days. Learning a programming language is important as it helps to improve the ability to automate, collect, handle, correctly interpret data and information. However, some students have difficulties to internalize the concepts and master the programming skills. Consequently, students tend to perceive programming course as a difficult subject. The objective of this paper is to present the design and implementation of a computer game application that focused on JAVA programming and Bloom’s taxonomy to enhance the students’ understanding. To evaluate the JAVA game application, functional and usability testing have been conducted that involved students from the Diploma of Computer Sciences Program in Universiti Teknologi MARA, Perak, Malaysia. The results were very encouraging as majority of students were satisfied with the JAVA game application by means of programming skill improvement and usability acceptance.

This paper presents an approach to support run-time verification of software systems that combines two existing tools, Prospec and Java-MaC, into a single framework. Prospec can be used to clarify natural language specifications for sequential, concurrent, and nondeterministic behavior. In addition, Prospec assists the user in reading, writing, and understanding formal specifications through the use of property patterns and visual abstractions. Prospec automatically generates specifications written in Future Interval Logic (FIL). Java-MaC monitors Java programs at runtime to ensure adherence to a set of formally specified properties. Safety properties of a program are specified in the formal language Meta-Event Definition Language (MEDL). Java-MaC generates runtime components from specifications. The components are used to instrument the target program and determine whether the execution of the program violates any of the safety properties. This paper describes an algorithm for translating FIL formulas into MEDL formulas. It provides the transformation rules used by this algorithm, and it demonstrates the general correctness of the translation.

The performance of operating systems like computers requires the proper functioning of the computer language interpreter. This interpreter follows various types of programming languages that make the performing of computer programming easy and effective. The application of the programming language of Java helps in processing multiple tasks at once. This research analyzes the novelty of Java-based data communication models in advanced computing services. This performance makes the saving of the resources used for the development of the programming language. All these development includes the performing of the multiple threads communication data processing. These multiple threads help distribute the single processed input in the multi-channel language processing, thus helping the work competition in time. It also reduces the cost of maintaining the programming languages reduced. Thus, the implementing cost of resources required for programming performance is reduced. Therefore, this implementation impacts the programmer to become more indented to use the language transformation process of Java. Moreover, it creates a more effective representation of the audio or visual content represented by a multi-tasking operating system. In this process of development in the language transformation of the operating system, the ability of the operating system for data processing improves. The systematic process of this language transformation helps in systematically transforming multiple programs at once.

Full textAbstract:
The syntax of Lisp languages is based on S-expressions, an extremely simple form of structured data representation that is nevertheless fundamental to the development of Lisp syntactic extensions. By adopting a more conventional syntax, the Java language placed itself in a difficult position in regard to user-defined syntax extensions. In spite of the many efforts to provide mechanisms for such extensions, they continue to be more difficult to use than S-expression- based ones. In this paper, we will describe the use of the S-expression syntax in a Java code generation environment. By providing an S-expression based program representation for Java source code, we are able to reuse and extend Lisp macro-expansion techniques to significantly simplify the construction of Java programs. .

Full textAbstract:
Programming is the cornerstone of computer science, yet it is difficult to learn and program. The syntax of a programming language is particularly challenging to comprehend, which makes learning arduous and affects the program's testability. There is currently no literature that definitively gives quantitative evidence about the effect of programming language complex syntax. The main purpose of this article was to examine the effects of programming syntax on the complexity of their source programs. During the study, 298 algorithms were selected and their implementations in Java and Python were analyzed with the cyclomatic complexity matrix. The results of the study show that Python's syntax is less complex than Java's, and thus coding in Python is more comprehensive and less difficult than Java coding. The Mann-Whitney U test was performed on the results of a statistical analysis that showed a significant difference between Java and Python, indicating that the syntax of a programming language has a major impact on program complexity. The novelty of this article lies in the formulation of new knowledge and study patterns that can be used primarily to compare and analyze other programming languages.

AbstractJava is not only a modern, powerful, and frequently used programming language, but together with Java Virtual Machine it represents a novel dynamic approach of writing and executing computer programs. The fact that Java programs are executed in a controlled environment has several important implications that define the nature of the language and makes it different from the traditional C-like languages. Knowing the detailed differences between the two types of languages and execution environments is a part of the holistic education of a computer engineer.In this paper, we present some behind-the-scene details about the Java Virtual Machine and we show how these details could be used in the educational process to demonstrate the differences and to emphasise the advantages of the dynamic programming approach when compared to the static one. After presenting some information about class files and about the internal structure and operation of the Java Virtual Machine we demonstrate the usage of public domain programs that could be used in the educational process to put these theoretical concepts into practice.

Full textAbstract:
Non-interference guarantees the absence of illicit information flow throughout program execution. It can be enforced by appropriate information flow type systems. Much of the previous work on type systems for non-interference has focused on calculi or high-level programming languages, and existing type systems for low-level languages typically omit objects, exceptions and method calls. We define an information flow type system for a sequential JVM-like language that includes all these programming features, and we prove, in the Coq proof assistant, that it guarantees non-interference. An additional benefit of the formalisation is that we have extracted from our proof a certified lightweight bytecode verifier for information flow. Our work provides, to the best of our knowledge, the first sound and certified information flow type system for such an expressive fragment of the JVM.

Programming is not just making a computer program, it can even create and control a computer according to the wishes of the maker. In its manufacture requires a certain language, one of which is the Java programming language. To become a reliable programmer, it should be learned first is about programming fundamentals. The goal is to learn programming fundamentals so that prospective programmers have a strong foundation in building a complex program. The major in vocational schools that study programming is the RPL (Software Engineering) major. To produce graduates who are skilled in programming, what must be taught first is the fundamentals of programming. So in class X, vocational school students are taught the fundamentals of programming with the Java programming language. In its implementation, this community service activity is divided into 4 stages, namely preliminary (field studies and signing of cooperation agreements), preparation of materials, training and quizzes, and evaluation. This training activity uses problem-based learning and project-based learning methods so that students are accustomed to solving problems that occur in the form of computer program projects. Training activities are carried out online through Zoom Meetings, while offline training is carried out at schools during visits at the beginning, middle, and end of the semester. In addition, there are also groups via Telegram as a medium for giving quizzes and discussions. Quiz is made in several models, namely in the form of multiple-choice, guess the output of program code, puzzles, and case studies that must be solved by programming. Each activity is given assessment points, namely online presence, offline activity, quiz answers, completion of challenges, and test scores.

Block-based programming languages (BBLs) have been proposed as a way to prepare students for learning to program in more sophisticated, text-based languages, such as Java. Hybrid BBLs add the ability to view and edit the block commands in auto-generated, text-based code. We compared the use of a non-hybrid BBL (Scratch), a hybrid BBL (Pencil Code), and no BBL across three sections of an introductory CS course that taught Java programming, to determine whether either type of BBL offered cognitive or affective advantages for learning Java. Students in the BBL groups were surveyed about their perceptions of each BBL in terms of ease of use and helpfulness in learning Java, and all three groups were compared on their performance in Java programming. The results showed that, in this introductory CS course, neither type of BBL offered an advantage in preparing students for learning Java. These results held regardless of the students’ level of Java knowledge prior to the course.

In this paper we have discussed one of the greatest features of the general purpose computer programming language –Java. This paper represents concepts of Synchronization possibilities and features in Java. Today's operating systems support concept of "Multitasking". Multitasking achieved by executing more than one task at a same time. Tasks runs on threads. Multitasking runs more than one task at a same time. Multitasking which means doing many things at the same time is one of the most fundamental concepts in computer engineering and computer science because the processor execute given tasks in parallel so it makes me think that are executing simultaneously. Multitasking is related to other fundamental concepts like processes and threads. A process is a computer program that is executing in a processor, while a thread is a part of a process that has a way of execution: it is a thread of execution. Every process has at least one thread of execution. There are two types of multitasking: process – based and thread – based. Process-based multitasking, means that on a given computer there can be more than one program or process that is executing, while thread-based multitasking, which is also known as multithreading, means that within a process, there can be more than one thread of execution, each of them doing a job and so accomplishing the job of their process. When there are many processes or many threads within processes, they may have to cooperate with each other or concurrently try to get access to some shared computer resources like: processor, memory and input/output devices. They may have to, for example: print a file in a printer or write and/or read to the same file. We need a way of setting an order, where processes and/or threads could do their jobs (user jobs) without any problem, we need to synchronize them. Java has built-in support for process and thread synchronization, there are some constructs that we can use when we need to do synchronization.This paper, a first phase discussed the concept of Parall Programming, threads, how to create a thread, using a thread, working with more than one thread.

Full textAbstract:
Source code comments can improve the efficiency of software development and maintenance. However, due to the heterogeneity of natural language and program language, the quality of code comments is not so high. So, this paper proposes a novel method Code2tree, which is based on the encoder-decoder model to automatically generate Java code comments. Code2tree firstly converts Java source code into abstract syntax tree (AST) sequences, and then the AST sequences are encoded by GRU encoder to solve the long sequence learning dependency problem. Finally, the attention mechanism is introduced in the decoding stage, and the quality of the code comment is improved by increasing the weight of the key information. We use the open dataset java-small to train the model and verify the effectiveness of Code2tree based on common-used indicators BLEU and F1-Score.

About 5–10% of software engineers suffer from repetitive strain injury, and it would be better to provide an alternative way to write code instead of using a mouse and keyboard and sitting on a chair the whole day. Coding by voice is an attractive approach, and quite a bit of work has been done in that direction. At the same time, dictating plain Java text with low accuracy through the existing voice recognition engines or providing complex panels controlled by the voice makes the coding process even more complex. We argue that current programming languages are suitable for programming by hand, not by mouth. We try to solve this problem by designing a new programming language, VoiceJava, suitable for dictating. A Java program is constructed in a syntax-directed way through a sequence of VoiceJava commands. As a result, users do not need to dictate spaces, parentheses, and commas, reducing the vocal load.

In the field of computer science the efforts made in solving a problem are to use systematic, logical, and strategic flow and steps. These steps are known as algorithms. So many algorithms exist for solving a particular problem. In connection with this paper the algorithm discussed is about the data sorting algorithm, among the few known are: Merge, Selection, Insertion, Bubble, Quick, Heap, Shell. All of these algorithms have advantages and disadvantages of each. One interesting algorithm to be implemented on 2 models of data sorting variants is the Bubble Sort algorithm, the reason is that this algorithm has a fairly long and detailed process flow to produce sequential data sequences from previously unsordered data sequences. And the purpose of implementing them using the language of the program is to be able to provide a translation picture of a complicated and long Bubble Sort algorithm that becomes easier and concise to solve using the program language, which in this case uses the Java program language. For ascending sequencing moving from left to right the method is by shifting the larger values to the right position in sequence, so that finally the smaller values are on the left, whereas for descending sorting moving from left to right the method is by shifting the smaller values to the right position in sequence, so that finally the larger values are on the left. And the programming technique differs only in relation operators that are used against the data being compared.

In this sense, we present a catalog with a set of refactorings to deal with lambda expressions in Java. A case study evaluates the applicability of the proposed refactorings in a set of open source projects, using an Eclipse-based tool for searching for refactoring opportunities dealing with lambda expressions.

Full textAbstract:
The most severe problem in cross-programming languages is feature extraction due to different tokens in different programming languages. To solve this problem, we propose a cross-programming-language vulnerability detection method in this paper, IRC-CLVul, based on intermediate representation and combined features. Specifically, we first converted programs in different programming languages into a unified LLVM intermediate representation (LLVM-IR) to provide a classification basis for different programming languages. Afterwards, we extracted the code sequences and control flow graphs of the samples, used the semantic model to extract the program semantic information and graph structure information, and concatenated them into semantic vectors. Finally, we used Random Forest to learn the concatenated semantic vectors and obtained the classification results. We conducted experiments on 85,811 samples from the Juliet test suite in C, C++, and Java. The results show that our method improved the accuracy by 7% compared with the two baseline algorithms, and the F1 score showed a 12% increase.

Cross-study courses are one of the programs of the Independent Campus Free Learning Curriculum. One of the courses offered across study programs by the Javanese Language and Literature Education Study program is the Macapat Song Arts Course. As a beginner learner in a song course, students will of course experience several problems, namely:1) The tone in the song is different from the tone of modern music (diatonic) which is usually heard and sung. Songs use pentatonic, so adjustments need to be made. 2) There are two types of tunings that students must also master, namely pelog and slendro with a different tone too. 3) Men's and women's voices have different ranges so they require different treatment. 4) the types of cengkok/types of songs in Macapat vary greatly, making it more difficult to memorize. In effort to ensure that students outside the Javanese Language and Literature Education study program need special treatment so that it is easier for them to take courses. Researchers in this case will design an Electronic Module for the Song Arts Course so that it can help students outside the Java study program learn Macapat songs. This research using the R&D Level 1 model, namely researching, producing designs, but not testing and producing them. Validation carried out by Javanese language material experts with a score of 3.7 and validation by design experts received a score of 3.78.

Full textAbstract:
Over the long history of the Internet, JavaScript has been the primary programming language in web development. Because of its simple syntax and support in all popular browsers, the language has gained popularity among the developers. However, as computer power and user demands evolved, simple sites turned into the web applications that are full-fledged analogues of the desktop applications. As capabilities grew, so did the performance requirements of such programs. Browser engines have developed ways to optimize the code they run, and intense competition between browsers has contributed to a qualitative increase in performance. Despite all the ways to increase the speed of execution of JavaScript code, the main stopping factor was the dynamic typing of the language. Because of dynamic typing, the browser engine needs to check each time the program is executed whether the variable is an integer, a float, or any other valid type. Thus, each JavaScript instruction has to go through several type checks and conversions, which slows down the execution. This led to the idea of using languages with strict typing, which could compensate for this drawback. But the browser engines cannot execute the code of other languages, that is why there appeared the technology WebAssembly. It allows writing code in languages with static typing, and then parses it into
a more native and machine-readable format, which speeds up execution of programs compared to JavaScript. The technology is cross-platform and supports the main programming languages: C++, C, Java, C#. WebAssembly is also implemented using JavaScript, which allows to use the concise JavaScript syntax and computing power of WebAssembly together.

Purpose The purpose of this paper is to find the most efficient assembly line balancing solution across many heuristic line balancing methods, in assistance with a developed computer program. Design/methodology/approach In this paper, assembly line balancing problem was analyzed using t-shirt and knitted pants data. A computer program using MATLAB software for the solution of assembly line balancing problems has been developed. In this study, following heuristic assembly line balancing methods were applied: Hoffman method; position weight method; COMSOAL method; and Kilbridge and Wester method. A MATLAB program has been developed by taking into account of theoretical solution of all these methods. Later the program is developed further by analyzing solutions made manually and is made to verify the developed program. Findings Pre-studies which were conducted in order to decide which programming language would be the best choice for line balancing methods’ application came out with the result that MATLAB, from between C, C++, C# and Java, would be the best software choice. The main reason for this choice is that MATLAB is a powerful matrix operation software with a powerful user interface designing tool and has the tools to make development program to be used universally in every computer. Originality/value When the researches were investigated, it is clearly seen that, this study is the first research on using computer program for solving assembly line balancing problem.

This study investigates out-of-Java students’ perceptions of their self-efficacy in English-speaking skills. To figure out their perceptions, the researchers formulated two research questions: (1) To what extent do out-of-Java students’ educational backgrounds impact their perceptions of self-efficacy in English speaking skills? (2) How do students cope with the challenges of speaking English? Participants in this study were the third-semester students from English Language Education Study Program. Written reflections and semi-structured interviews were chosen as the primary data collection methods. In analyzing the data, Thematic Analysis was employed in this study. The researchers described the participants’ self-reflections and transcribed their interviews. This study revealed two important results. First, there was an influence of participants' educational backgrounds on their perception of self-efficacy in English-speaking skills. Second, the participants had their strategies in overcoming the difficulties that they experienced in speaking. The results of the study showed that out-of-Java students have high self-efficacy beliefs which increase with their time at university and can improve their English-speaking skills by applying some learning strategies.

AbstractTesting is a vital part of the software development process. Test Case Generation (TCG) is the process of automatically generating a collection of test-cases which are applied to a system under test. White-box TCG is usually performed by means of symbolic execution, i.e., instead of executing the program on normal values (e.g., numbers), the program is executed on symbolic values representing arbitrary values. When dealing with an object-oriented (OO) imperative language, symbolic execution becomes challenging as, among other things, it must be able to backtrack, complex heap-allocated data structures should be created during the TCG process and features like inheritance, virtual invocations and exceptions have to be taken into account. Due to its inherent symbolic execution mechanism, we pursue in this paper that Constraint Logic Programming (CLP) has a promising application field in tcg. We will support our claim by developing a fully CLP-based framework to TCG of an OO imperative language, and by assessing it on a corresponding implementation on a set of challenging Java programs.

elPrep is an extensible multithreaded software framework for efficiently processing Sequence Alignment/Map (SAM)/Binary Alignment/Map (BAM) files in next-generation sequencing pipelines. Similar to other SAM/BAM tools, a key challenge in elPrep is memory management, as such programs need to manipulate large amounts of data. We therefore investigated 3 programming languages with support for assisted or automated memory management for implementing elPrep, namely C++, Go, and Java. We implemented a nontrivial subset of elPrep in all 3 programming languages and compared them by benchmarking their runtime performance and memory use to determine the best language in terms of computational performance. In a previous article, we motivated why, based on these results, we eventually selected Go as our implementation language. In this article, we discuss the difficulty of achieving the best performance in each language in terms of programming language constructs and standard library support. While benchmarks are easy to objectively measure and evaluate, this is less obvious for assessing ease of programming. However, because we expect elPrep to be regularly modified and extended, this is an equally important aspect. We illustrate representative examples of challenges in all 3 languages, and give our opinion why we think that Go is a reasonable choice also in this light.

Full textAbstract:
ABSTRACTA set of computer programs has been developed to draw chemical-equilibrium diagrams. This new software is the Java-language equivalent to the Medusa/Hydra software (developed some time ago in Visual basic at the Royal Institute of Technology, Stockholm, Sweden). The main program, now named “Spana” calls Java programs based on the HaltaFall algorithm. The equilibrium constants that are needed for the calculations may be retrieved from a database included in the software package (“Database” program). This new software is intended for undergraduate students as well as researchers and professionals.The “Spana” code can be easily applied to perform radionuclide speciation and solubility calculations of minerals, including solubility calculations relevant for the performance assessment of a nuclear waste repository. In order to handle ionic strength corrections in such calculations several approaches can be applied. The “Spana” code is able to perform calculations based on three models: the Davies equation; an approximation to the model by Helgeson et al. (HKF); and the Specific Ion-Interaction Theory (SIT). Default SIT-coefficients may be used, which widens the applicability of SIT significantly.A comparison is made here among the different ionic strength approaches used by “Spana” (Davies, HKF, SIT) when modelling the chemistry of radionuclides and minerals of interest under the conditions of a geological repository for nuclear waste. For this purpose, amorphous hydrous Thorium(IV) oxide (ThO2(am)), Gypsum (CaSO4·2H2O) and Portlandite (Ca(OH)2) solubility at high ionic strengths have been modelled and compared to experimental data from the literature. Results show a good fitting between the calculated values and the experimental data especially for the SIT approach in a wide range of ionic strengths (0-4 M).

Computer simulations provide students the opportunity to observe and interact in realistic biological experiences. This designed simulation, “The Trio of Genetic Diversity,” made it easier for students to grasp the reasons for genetic diversity. During and after meiosis, the three processes (crossing over, independent assortment, and random fertilization) that occur are the primary sources of diversity. A separate module was designed for each of the three processes and presented in the order of occurrence. It will take three to five minutes for student to try each module. The simulation in this study was developed using Java programming language in the NetBeans IDE 8.2 development environment, along with the Swing GUI module. Java was used in the simulation so that it can be run easily in almost every operating system; furthermore, the interface is included in the Java library. The NetBeans IDE 8.2 software allowed the simulations to show the range of possibilities for genetic diversity. Chromosome images were created and converted into a transparent structure, and the coding process was started. The images and button actions in the simulation interface were carefully designed so that the user could understand them easily. This article introduces the simulation program and its features.

VisibleZ models IBM’s z/Architectureand allows direct interpretation of mainframe assembly language objectcode in a graphical user interface environment that was developed in Java.The VisibleZ emulator acts as an interactive visualization tool to simulateenterprise computer architecture. The provided architectural componentsinclude main storage, CPU, registers, Program Status Word (PSW), andI/O Channels. Particular attention is given to providing visual clues tothe user by color-coding screen components, machine instruction execution,and animation of the machine architecture components. Students interact with VisibleZ by executing machine instructions in a step-by-stepmode, simultaneously observing the contents of memory, registers, and changes inthe PSW during the fetch-decode-execute machine instruction cycle. Theobject-oriented design and implementation of VisibleZ allows students todevelop their own instruction semantics by coding Java for existing specificz/Architecture machine instructions or design and implement new machineinstructions. The use of VisibleZ in lectures, labs, and assignments is describedin the paper and supported by a website that hosts an extensivecollection of related materials.

The Open Microscopy Environment Remote Objects (OMERO) is an open source image manager used by many biologists to store, organize, view and share microscopy images, while the open source software ImageJ/Fiji is a very popular program used to analyse them. However, there is a lack of an easy-to-use generic tool to run a workflow on a batch of images without having to download them to local computers; and to automatically organize the results in OMERO. To offer this functionality, we have built three tools in Java language: “Simple OMERO Client”, a library to communicate with an OMERO database from Java softwares ; an ImageJ/Fiji plugin to run a macro-program on a batch of images from OMERO and “OMERO Macro extensions“, a dedicated vocabulary to interact with OMERO in macro-programming. The latter is intended for developers, with additional possibilities using tag criteria, while the “Batch OMERO plugin” is more geared towards non-IT scientists and has a very easy to use interface. Both tools are illustrated with a use case.

Programming languages are a vital domain for Computer and Information Technology engineering. The programming languages like C, C++, Java, Python, Mobile Application Development, and Web Technologies are important programming courses in CSE and IT curriculum. Understanding the programming courses includes a basic understanding of the syntax of programming language, logical & critical thinking to solve the problem, use of various editors to write and execute the program. Effective delivery of the programming course creates a great deal of influence on student’s interest in programming and software development. The students lose their interest in programming due to the inefficient delivery of these courses which leads to a gap in technical competency required by the IT sector. The current Covid 19 pandemic exposed the limitation of traditional teaching methods for programming courses. Teaching such programming courses on online mode becomes a big challenge for faculty by considering the skillset required to inculcate amongst the students for learning programming courses. The primary objective of this paper is to overcome these challenges by the effective use of a pedagogical approach for teaching programming courses. The various active learning methods and tools are discussed in this paper that was used to teach the programming language. The result shows that by implementation of such methods & tools you can retain the interest of students in programming courses and thus increase their performance and improve the skillset required in IT industry.

Crime statistics from the US Bureau of Justice and the FBI Uniform Crime Report show a gap between reported and unreported crime. For police to effectively prevent and solve crime, they require accurate and complete information about incidents. This article describes the evaluation of a crime reporting and interviewing system that witnesses can use to report crime incidents or suspicious activities anonymously while ensuring the information received is of such quality that police can use it to begin an investigation process. The system emulates the tasks that a police investigator would perform by leveraging natural language processing technology and the interviewing techniques used in the Cognitive Interview. The system incorporates open-source code from the General Architecture for Text Engineering (GATE) program developed by researchers at the University of Sheffield, Web and database technology, and Java-based proprietary code developed by the author. Findings of this evaluation show that the system is capable of producing accurate and complete reports by enhancing witnesses' memory recall and that its efficacy approximates the efficacy of a human conducting a cognitive interview closer than existing alternatives. The system is introduced as the first computer application of the cognitive interview and proposed as a viable alternative to face-to-face investigative interviews.

Abstract. Computer programming has become a relevant element of the modern era. Practically it is involved in all sectors of modern society. Currently, many universities around the globe offer bachelor’s degree programs that contain computer programming related courses. In order to gain insight into how computer programming is taught in Ecuadorian Higher Education Institutions (HEIs), we have conducted the first national survey on teaching computer programming in undergraduate CS programs. In this survey participated 53 respondents from 13 Ecuadorian HEIs. We report on programming paradigms, programming languages, integrated development environments and teaching strategies used in the programming learning process. We found that the object-oriented paradigm along with the Java programming language are the most often used. The NetBeans integrated development environment is the most commonly used among the respondents. Concerning teaching strategies, e-learning platforms are commonly used as part of computer programming courses. More than half of the respondents use collaborative strategies such as pair programming in their courses. Finally, a half of the respondents use traditional computer labs for teaching programming; however, other approaches such as mobile devices, games and simulations, Arduino kits and robots start to be used as a teaching strategy. Our findings can serve as a starting point for addressing reforms in computer programming courses taught in Ecuadorian CS undergraduate programs.

We used PHP and Java Script as the program languages, PostgresSQL as the database management system on an Apache web server and Linux as the operating system. A system which allows for user input and searching within inputted items and creates tests was constructed. We performed an ability estimation on each test based on a Rasch model and 2- or 3-parametric logistic models. Our system provides an algorithm for a web-based CAT, replacing previous personal computer-based ones, and makes it possible to estimate an examinee?占퐏 ability immediately at the end of test.

The manipulation of components and composition operations at the programming language level allows for the compile time verification, by a type system, of safety structural properties of ComponentJ programs. This work is based on earlier fundamental results where the main concepts are presented and justified in the form of a core component calculus. .

Full textAbstract:
Education is one of the aspects affected by the Covid-19 pandemic. The online learning that has been taken since the outbreak began in March 2020 has an impact on the effectiveness of the learning outcomes themselves. This research is a qualitative research that aims to obtain a description of online learning for the Learning Evaluation course at the Javanese Language and Literature Education Study Program, Faculty of Language and Arts, Universitas Negeri Semarang, even semester 2020/2021. Online learning at Unnes uses the Elena system to support optimizing lecture outcomes. The technique of collecting data in this study used a questionnaire technique with 92 respondents in the sixth semester of the Java Language and Literature Education Study Program who took the Learning Evaluation course. The data analysis technique uses the Miles & Huberman (1994) technique which consists of three stages, namely data reduction, data display, and drawing conclusions and reflections. The results of this study indicate that online learning has been effective in achieving the learning objectives of the course, but it needs to be improved so that it is more structured in providing online material. The results of this study are used as guidelines for improving online learning, especially in the Learning Evaluation course in the coming semester and online learning in all courses in general.

This study investigated how prospective English as a foreign language teachers perceived the role of their teachers in online learning and how those roles contributed to their experiences in a low-tech online learning context. This study surveyed 285 prospective teachers at seven universities across provinces with English Language Education programs in Indonesia (East Java, North Sumatera, Central Sulawesi, West Kalimantan, West Papua, East Nusa Tenggara and Bali) and interviewed 10 prospective teachers to provide a deeper understanding of their experiences. The results showed that the cognitive role is the most important teacher role perceived by prospective teachers in a low-tech online learning context. Three themes emerged from the results: the teacher’s cognitive sub-roles in providing learning assistance and recommendation, managerial sub-roles in leading, controlling and organizing the learning process and affective sub-roles in creating an enjoyable, relaxing learning environment and catching students’ attention in online learning. The discussion focuses on the different effects of the roles on creating a positive online learning environment for students. In conclusion, teaching skills related to the three roles of teachers in online learning must be taught explicitly in a teacher-training program through scenario-based learning activities. The implications of teacher-training programs are discussed further in this paper.

Design patterns are generic solutions to common programming problems. Design patterns represent a typical example of design reuse. However, implementing design patterns can lead to several problems, such as programming overhead and traceability. Existing research introduced several approaches to alleviate the implementation issues of design patterns. Nevertheless, existing approaches pose different implementation restrictions and require programmers to be aware of how design patterns should be implemented. Such approaches make the source code more prone to faults and defects. In addition, existing design pattern implementation approaches limit programmers to apply specific scenarios of design patterns (e.g. class-level), while other approaches require scattering implementation code snippets throughout the program. Such restrictions negatively impact understanding, tracing, or reusing design patterns. In this paper, we propose a novel approach to support the implementation of software design patterns as an extensible Java compiler. Our approach allows developers to use concise, easy-to-use language constructs to apply design patterns in their code. In addition, our approach allows the application of design patterns in different scenarios. We illustrate our approach using three commonly used design patterns, namely Singleton, Observer and Decorator. We show, through illustrative examples, how our design pattern constructs can significantly simplify implementing design patterns in a flexible, reusable and traceable manner. Moreover, our design pattern constructs allow class-level and instance-level implementations of design patterns.

ABSTRACT A new computer program, called Mallard, is presented for screening entire 16S rRNA gene libraries of up to 1,000 sequences for chimeras and other artifacts. Written in the Java computer language and capable of running on all major operating systems, the program provides a novel graphical approach for visualizing phylogenetic relationships among 16S rRNA gene sequences. To illustrate its use, we analyzed most of the large libraries of cloned bacterial 16S rRNA gene sequences submitted to the public repository during 2005. Defining a large library as one containing 100 or more sequences of 1,200 bases or greater, we screened 25 of the 28 libraries and found that all but three contained substantial anomalies. Overall, 543 anomalous sequences were found. The average anomaly content per clone library was 9.0%, 4% higher than that previously estimated for the public repository overall. In addition, 90.8% of anomalies had characteristic chimeric patterns, a rise of 25.4% over that found previously. One library alone was found to contain 54 chimeras, representing 45.8% of its content. These figures far exceed previous estimates of artifacts within public repositories and further highlight the urgent need for all researchers to adequately screen their libraries prior to submission.
