In their own words
BlueJ
BlueJ is a free development environment for building Java programs, designed for beginners and teaching. It runs on Windows, macOS and Linux, with current downloads requiring a 64-bit operating system. Its interactive tools let users create and inspect objects, call methods, and evaluate Java expressions without compiling. In the editor, scope highlighting distinguishes code blocks and can help reveal misplaced curly brackets. BlueJ 6.0.0 added Kotlin editing and execution, though some Kotlin features, including code completion, are not supported. Documentation includes a Git teamwork tutorial for BlueJ 4 and later. Third parties can add functionality through an extensions API; the listed extensions page covers BlueJ 4 and older, while BlueJ 5.0.0 rewrote the API. The free Blueroom site offers teaching resources for educators. BlueJ directs software questions to its FAQ, technical support contact and bug database, and says it aims to respond to technical support requests within one working day.
Eclipse IDE
Eclipse IDE is a free development platform for building integrated tools and rich client applications, available for Windows, macOS, and Linux. Its Java Developers package combines a Java IDE with a Git client, XML editor, and Maven and Gradle integration. The 2026-09 release supports Java 26 and includes a compact source file wizard for Java 25 and later projects, plus a quick assist for converting enhanced for loops to forEach statements. Other platform features include regular expression content assistance in find and replace, console zoom controls, and search filters in Problems, Tasks, and Bookmarks views. Packages cover Java, Enterprise Java and web, C/C++, embedded C/C++, PHP, DSLs, and other development areas. Eclipse Marketplace plugins can extend the platform. The Eclipse Foundation provides project security support, and users can seek community help through its chat space or report issues through its problem reporting process. The Foundation’s default project license is the Eclipse Public License unless project documentation says otherwise. The Eclipse Foundation is an international non-profit association based in Brussels.
