Apache NetBeans vs CS++ Java IDE

Apache NetBeans is a development environment, tooling platform, and application framework for Linux, macOS, and Windows. Its editor highlights code by syntax and meaning and supports refactoring. Editors, wizards, and templates cover Java, PHP, and other languages, with plugins and linked support for JavaFX and JavaScript. The NetBeans Platform is a modular framework for Swing applications, with state saving, menus, toolbars, keyboard shortcuts, and window management. The IDE and Platform are free for commercial and non-commercial use under the Apache License; the listed plan is free. Apache NetBeans 31, dated August 10, 2026, supports running on JDK 26, 25, or 21, with initial support for JDK 27. Downloads include platform-independent binary and source ZIPs, plus linked installers for Windows, macOS, and Linux. Those installers are provided by committers for convenience, not as Apache Software Foundation releases. The release page provides SHA-512 hashes and PGP signatures. Windows/ARM is not fully supported, and older releases are no longer supported.

CS++ Java IDE lets users write and run Java in a browser without installing a JDK. Its custom interpreter handles most of Java and core standard-library features, including classes, generics, collections, lambdas, and streams. A step-through debugger and clear error messages are included for beginners. The runtime does not support threads, writing files, reflection, enums, records, or switch expressions. The browser IDE works on Chromebooks, iPads, phones, Macs, and Windows PCs, including locked-down school devices. Users can begin without an account; signing in is optional and adds cloud saving across devices. Teachers can share starter code and worked examples by link, and use the IDE for demonstrations and homework. It is aimed at beginners and AP Computer Science A students, with supported topics extending beyond the exam to generics, collections, lambdas, and streams. The free plan supports writing, running, and auto-testing Java in a browser without signup to start. The listed pricing note says paid access starts at $9.99, though no paid plan details are provided here.
