JD Decompiler
JD (Java Decompiler) is a decompiler for the Java programming language. JD is provided as a GUI tool as well as in the form of plug-ins for the Eclipse (JD-Eclipse) and IntelliJ IDEA (JD-IntelliJ) integrated development environments. JD supports most versions of Java from 1.1.8 through 1.7.0 as well as JRockit 90_150, Jikes 1.2.2, Eclipse Java Compiler and Apache Harmony and is thus often used where formerly the popular JAD was operated. Variants In 2011, Alex Kosinsky initiated a variant of JD-Eclipse which supports the alignment of decompiled code by the line numbers of the originals, which are often included in the original Bytecode as debug information. In 2012, a branch of JDEclipse-Realign by Martin "Mchr3k" RobertsonMartin "Mchr3k" RobertsonJDEclipse-Realign.Version 1.1.2 of January 6th, 2013. Accessed March 30th, 2013. Hosted by GitHub. extended the functionality by manual decompilation control and support for Eclipse 4.2 (Juno). See also * JAD (software) Jad ...

Java Decompiler
A decompiler is a computer program that translates an executable file to a high-level source file which can be recompiled successfully. It does therefore the opposite of a typical compiler, which translates a high-level language to a low-level language. Decompilers are usually unable to perfectly reconstruct the original source code, thus frequently will produce obfuscated code. Nonetheless, decompilers remain an important tool in the reverse engineering of computer software. Introduction The term ''decompiler'' is most commonly applied to a program which translates executable programs (the output from a compiler) into source code in a (relatively) high level language which, when compiled, will produce an executable whose behavior is the same as the original executable program. By comparison, a disassembler translates an executable program into assembly language (and an assembler could be used for assembling it back into an executable program). Decompilation is the act of usin ...

Jikes
Jikes is an open-source Java compiler written in C++. It is no longer being updated. The original version was developed by David L. "Dave" Shields and Philippe Charles at IBM but was quickly transformed into an open-source project contributed to by an active community of developers. Initially hosted by IBM, the project was later transferred to SourceForge. Among its accomplishments, it was much faster in compiling small projects than Sun's own compiler, and provided more helpful warnings and errors. Project status the project is no longer being actively developed. The last 1.22 version was released in October 2004 and partially supports Java 5.0 (with respect to new classes, but not new language features). As no further versions were released since, Java SE 6 is not supported. While the free software community needed free Java implementations, the GNU Compiler for Java became the most commonly used compiler. See also * Jikes RVM References External links * {{sourceforg ...

It provides the distributed version control of Git plus access control, bug tracking, software feature requests, task management, continuous integration, and wikis for every project. Headquartered in California, it has been a subsidiary of Microsoft since 2018. It is commonly used to host open source software development projects. As of June 2022, GitHub reported having over 83 million developers and more than 200 million repositories, including at least 28 million public repositories. It is the largest source code host . History GitHub.com Development of the GitHub.com platform began on October 19, 2007. The site was launched in April 2008 by Tom Preston-Werner, Chris Wanstrath, P. J. Hyett and Scott Chacon after it had been made available for a few months prior as a beta release. GitHub has an annual keynote called GitHub Universe. Organizational ...

Branching (revision Control)
Branching, in version control and software configuration management, is the duplication of an object under version control (such as a source code file or a directory tree). Each object can thereafter be modified separately and in parallel so that the objects become different. In this context the objects are called branches. The users of the version control system can branch any branch. Branches are also known as ''trees'', ''streams'' or ''codelines''. The originating branch is sometimes called the ''parent branch'', the ''upstream branch'' (or simply ''upstream'', especially if the branches are maintained by different organizations or individuals), or the ''backing stream''. ''Child branches'' are branches that have a parent; a branch without a parent is referred to as the trunk or the ''mainline''. The trunk is also sometimes loosely referred to as HEAD, but properly head refers not to a branch, but to the most recent commit on a given branch, and both the trunk and each named b ...

Debugger
A debugger or debugging tool is a computer program used to software testing, test and debugging, debug other programs (the "target" program). The main use of a debugger is to run the target program under controlled conditions that permit the programmer to track its execution and monitor changes in computer resources that may indicate malfunctioning code. Typical debugging facilities include the ability to run or halt the target program at specific points, display the contents of memory, CPU registers or storage devices (such as disk drives), and modify memory or register contents in order to enter selected test data that might be a cause of faulty program execution. The code to be examined might alternatively be running on an ''instruction set simulator'' (ISS), a technique that allows great power in its ability to halt when specific conditions are encountered, but which will typically be somewhat slower than executing the code directly on the appropriate (or the same) processor ...

Bytecode
Bytecode (also called portable code or p-code) is a form of instruction set designed for efficient execution by a software interpreter. Unlike human-readable source code, bytecodes are compact numeric codes, constants, and references (normally numeric addresses) that encode the result of compiler parsing and performing semantic analysis of things like type, scope, and nesting depths of program objects. The name bytecode stems from instruction sets that have one-byte opcodes followed by optional parameters. Intermediate representations such as bytecode may be output by programming language implementations to ease interpretation, or it may be used to reduce hardware and operating system dependence by allowing the same code to run cross-platform, on different devices. Bytecode may often be either directly executed on a virtual machine (a p-code machine, i.e., interpreter), or it may be further compiled into machine code for better performance. Since bytecode instructions ar ...

Apache Harmony
Apache Harmony is a retired Open-source software, open source, free Java implementations, free Java implementation, developed by the Apache Software Foundation. It was announced in early May 2005 and on October 25, 2006, the Board of Directors voted to make Apache Harmony a top-level project. The Harmony project achieved (as of February 2011) 99% completeness for J2SE 5.0, and 97% for Java SE 6. The Android (operating system), Android operating system has historically been a major user of Harmony, although since Android Nougat it increasingly relies on OpenJDK libraries. On October 29, 2011 a vote was started by the project lead Tim Ellison whether to retire the project. The outcome was 20 to 2 in favor, and the project was retired on November 16, 2011. History Initiation The Harmony project was initially conceived as an effort to unite all developers of the free Java implementations. Many software developer, developers expected that it would be the project above the GNU, ...

JRockit
JRockit was a proprietary Java virtual machine (JVM) originally developed by Appeal Virtual Machines, acquired by BEA Systems in 2002, and became part of Oracle Fusion Middleware as part of acquisition of BEA Systems in 2008. The JRockit code base was discontinued by Oracle, with some features being integrated into the HotSpot virtual machine as part of the mainline development of the Java platform. JRockit only ever supported Java 6, which is now considered an obsolete release. History Following the finalization of the acquisition of Sun Microsystems, Oracle announced in JavaOne 2010 that the best features of JRockit would be implemented in OpenJDK. In May 2011, Oracle announced that JRockit has become free, and confirmed the plan to port JRockit features on OpenJDK OpenJDK (Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE). It is the result of an effort Sun Microsystems began in 2006. The implementation i ...
