What is BlueJ?

BlueJ is an integrated Java development environment designed primarily for beginner-level programming, learning and teaching. Suited for small-scale development, the free technology provides  an easy-to-use and interactive interface designed for interactive creation and invocation of objects.

With a design that is notably different from other IDE software, BlueJ was created specifically to promote the learning and teaching of object-oriented programming. Its main screen visually displays the graphic class structure of an application under development, via a UML-like diagram. Users can interactively create and test objects. The interactive functionalities merged with a straightforward and clean user interface results to easy experimentation of objects that are under development.


Overview of BlueJ Benefits

BlueJ is a development environment that is specifically designed to aid in introductory Java programming. Its interface is smaller and simpler compared to professional-level IDE software that tend to overwhelm beginners. The straightforward and basic display help new users get started on basic development more easily and quickly.  

Since it was customized for teaching, BlueJ was created with good principles and methods of instructions in mind. The program has a renowned textbook for teaching introductory universities and college courses with BlueJ, as well as a webpage containing comprehensive teaching resources.

BlueJ allow users to interact with objects – from inspecting their value, calling methods on them, pass them as parameters, and more. Users can also directly invoke Java expressions without compiling, making BlueJ an effective graphical shell/REPL for Java.

BlueJ is portable and supports deployment on a variety of operating systems. The free technology runs on Windows, Mac OS X, Linux and other platforms which run Java. It can also run without installation from a USB stick.

BlueJ has a number of innovative features that are not available in other IDEs. Original BlueJ features include its object bench, code pad, and scope coloring. Unique scope highlighting, where the background of each code block is colored, helps users scan codes more quickly and recognizes misplaced curly brackets.
