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. When you create a new class, BlueJ generates a clean but robust template with hints toward what you need to do. As you build a project, you see a "mind map" or flowchart of how your Java files fit together. ![]() BlueJ templatesīlueJ's interface is clean and simple, with just four items in its main menu bar. The University of Kent is sensitive to this beginner-level struggle, so it develops and maintains BlueJ, an open source integrated development environment (IDE) for Java learners. For instance, a Java class often looks something like this: import java.io.Foo Other times, the introductory text is more complex. 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. Before you can get comfortable starting a project, you have to remember the preambles that, in theory, ought to be easy to remember since they're usually relatively short and repetitive. ![]() Whenever you're learning a new programming language, it's easy to criticize all the boilerplate text you need to memorize.
