Open Source Java Integrated Development Environments (IDE) for Linux

IntelliJ Community is the open source upstream of JetBrains’ IntelliJ IDEA, forming the core of a powerful, extensible, and intelligent development environment. It provides foundational features like a robust editor with code completion, syntax highlighting, refactoring tools, version control integrations, terminal, debugger, and plugin architecture. Since it’s open, community developers can contribute to language supports, UI tweaks, and platform enhancements. From this base, JetBrains builds full editions (Ultimate) by layering proprietary features for enterprise frameworks and integrations. IntelliJ Community supports multiple JVM-based languages (Java, Kotlin, Scala, Groovy) and serves as a host for plugin ecosystems that add support for web, database, and cloud tooling. The project emphasizes performance, modularity, and a responsive user experience, maintaining a codebase that balances long-term maintainability with cutting-edge developer features.

PyDev is a Python Development Environment (Python IDE plugin for Eclipse). It features an editor with code completion, code analysis, refactoring, outline view, debugger, mark occurrences and other goodies - check http://pydev.org for more details). It's kept going by community contributions, so, if you think it's a worthy project, please contribute through http://pydev.org

jVi is a vi/vim editor clone built on top of the javax.swing.text package. Available for NetBeans and JBuilder. jVi is designed to quickly and easily integrate into many disparate java based desktop apps, from IDE's to mail-news readers.

Apache NetBeans is much more than a text editor. It highlights source code syntactically and semantically, lets you easily refactor code, with a range of handy and powerful tools. Apache NetBeans provides editors, wizards, and templates to help you create applications in Java, PHP and many other languages. Apache NetBeans can be installed on all operating systems that support Java, i.e, Windows, Linux, Mac OSX and BSD. Write Once, Run Anywhere, applies to NetBeans too.

An IDE to develop real, Gradle-based Android applications on Android devices.

CP Editor is designed for competitive programming. It helps you focus on your algorithms and automates the compilation, execution and testing of your code. It can fetch test cases from different platforms and submit solutions to Codeforces. It automates all that's reasonably possible and allows you to purely focus on your code. Say no to manual efforts of running and testing your code against expected outputs. It can fetch test cases automatically from almost all competitive programming sites. No more copy-pasting! With a single click, you can run your code on multiple test cases and get verdicts. Thanks to CF tools, It can submit your solution directly to codeforces and show you verdict without leaving the editor.

Coded is a graphically oriented source code editor. With the use of class and method wizards, advanced code manipulation via drag-and-drop, automatic code formatting, and autocomplete/completion suggestion, Coded will make the process of editing a breeze

This project was created to show a way to highlight keywords of any language in a simple way. The resource which has been used is ANLTR (www.antlr.org). You are free to adapt it for your language, you just have to define the keywords in the grammar file.

codeSlinger is source code editor / integrated development environment designed for programmers. It is flexible enough to be used with virtually any programming language, yet powerful enough to develop large projects. codeSlinger itself, for instance was
