The most helpful aspects of BlueJ are its simple interface, interactive object creation, and lightweight design. It allows beginners to visualize classes, test methods without a `main` method, and debug code easily. Ideal for learning OOP concepts efficiently.

The best thing about BlueJ is how easy it is to use, especially if you're just starting with Java. The interface is super simple and not overwhelming like some of the bigger IDEs. I also love how you can interact with objects directly, like creating instances and calling methods without needing to run a whole program. It really helps understand object-oriented programming better. Also, it’s lightweight and doesn’t need a super powerful computer to run, which is nice.
