By using colored backgrounds, BlueJ helps you visualize the structure of the code you're writing. It can be nearly impossible to tell a variable apart from a keyword that's a part of the language, and even with the assistance of indentation and braces and semicolons, it all starts to blur together.īlueJ is designed to clear away this confusion. It doesn't help that when you're learning to program, most of the code you type looks and feels basically the same: it's all vaguely meaningful, yet oddly similar, with words that seem to make as much sense whether you read them backward or forward. If you're new to programming-or just new to Java, it can be difficult to understand advanced concepts like variable scoping and loops and conditionals.
It uses a subdued color scheme to keep different code elements separate from one another, so it's easy to tell a class from a method or a comment.

For example, a shell script opens with a simple "shebang": #!/bin/sh In practice, though, boilerplate text is too obscure in meaning to become an easy habit, but it's essential for a program to run.
