- Simple - BlueJ has a deliberately smaller and simpler interface than professional environments like NetBeans or Eclipse. This allows beginners to get started more quickly, and without being overwhelmed.
- Designed for teaching - BlueJ is deliberately designed with good pedagogy in mind. There is a popular textbook designed for teaching introductory university/college courses with BlueJ, and a site full of teaching resources.
- Interactive BlueJ - allows you to interact with objects. You can inspect their value, call methods on them, pass them as parameters and more. You can also directly invoke Java expressions without compiling. Thus BlueJ for macOS is a powerful graphical shell/REPL for Java.
- Portable BlueJ - runs on Windows, macOS, Linux and other platforms which run Java. It can also run without installation from a USB stick.
- Mature BlueJ - is over fifteen years old, but continues to be updated and supported by a full-time team. 'We aim to respond to all technical support requests within one working day.'
- Innovative BlueJ - has several features not seen before in other IDEs. Its object bench, code pad, and scope coloring were all original BlueJ features.
BlueJ's editor features unique scope highlighting, where the background of each code block is colored to allow you to visually scan the code much faster. It also helps in spotting misplaced curly brackets. Objects can be inspected while the program is running. The contents of fields are displayed to aid understanding and debugging. As well as allowing inspection of objects while the program is running, objects can be dynamically created, and their methods can be invoked. You can also invoke Java code directly, without compilation, just by typing it in. The result is printed out, and can then be inspected, manipulated, or passed as a parameter to another method call.

Many Adobe applications depend on the Oracle Java Runtime Environment (JRE) for some features to work. Apple recently changed the way it includes Java in Mac OS, and with Lion, Java is no longer preinstalled. It is now an optional install that you must select.
Since current Adobe installers and applications were built before these changes by Apple, Adobe software anticipates that Java is installed. Adobe and Apple have worked together to ensure that you can install Java at OS install time. Or it can be installed later before you install Adobe applications. At runtime, when you launch an Adobe application, you are prompted to install Java if it is not already installed. If you do not install Java before running an Adobe application, there can be missing or improperly behaving features. If you encounter any issues, install Java to correct the problems. Adobe recommends that corporate IT organizations pre install Java (or make sure that Java can be installed through their firewalls/security) to avoid conflicts with Adobe applications.
