BlueJ is a free Java Development Environment designed for beginners, used by millions worldwide. Developed mainly for educational purposes, but also suitable for small-scale software development. It runs with the help of JDK (Java Development Kit). It was developed to support the learning and teaching of object-oriented programming, and its design differs from other development environments as a result.

One of my favourite IDEs out there is BlueJ — James Gosling, creator of Java.

The main screen graphically shows the class structure of an application under development (in a UML-like diagram), and objects can be interactively created and tested. This interaction facility, combined with a clean, simple user interface, allows easy experimentation with objects under development. Object-oriented concepts (classes, objects, communication through method calls) are represented visually and in its interaction design in the interface.


The BlueJ interface emphasises class structure (in preference of source code) by showing a UML-like diagram as its main screen. Class structures can be manipulated by the user, and the class relation display is generated automatically from the source code.

Source level structure is visualised through scope highlighting (the visual emphasis of lexical scope through use of graphical frames and background colour).

Interaction and experimentation

Supported interaction features include the ability to create objects interactively for ad-hoc testing and experimentation, and support for interactive invocation of public methods. Parameters may be passed and objects can be composed in interactive calls.

Interactive tests may be recorded and stored as standard unit test classes. Code fragments can be evaluated interactively in the Code Pad, which provides a Java-based REPL.

Supported languages

BlueJ supported programming in Java and in Stride.
