Features and Benefits of BlueJ

BlueJ has several features that make it a good choice for learning Java programming. Here are some of them:

Simple and user-friendly interface

BlueJ has a deliberately smaller and simpler interface than professional IDEs like Eclipse or IntelliJ IDEA. This makes it easier for beginners to get started and avoid being overwhelmed by too many options and menus. BlueJ shows you the class structure of your application in a graphical way, using a UML-like diagram. You can easily create new classes, edit existing ones, or delete them. You can also drag and drop classes to organize them in packages.

Designed for teaching and learning Java

BlueJ is not only an IDE, but also a teaching tool. It comes with a popular textbook called "Objects First with Java: A Practical Introduction Using BlueJ", which is co-written by the developers of BlueJ. The textbook covers the basics of object-oriented programming using Java, and provides many examples and exercises that you can follow along using BlueJ. There is also a website called Blueroom that offers teaching resources and a community of educators who use BlueJ around the world.

Interactive and innovative tools

BlueJ allows you to interact with objects while your program is running. You can create new objects, inspect their values, call their methods, pass them as parameters, or delete them. You can also invoke Java expressions directly without compiling them, just by typing them in the code pad. This way, you can experiment with your code and see the results immediately. BlueJ also has some unique features that are not seen in other IDEs, such as scope coloring, object bench, code pad, and extensions.
