DrJava

DrJava provides an intuitive programming environment that can assist students in creating their own Java applications. While its main purpose is to help beginners focus on the development process, rather than learning how the application works, it also comes with a set of advanced features designed to meet the requirements of more advanced users.

The main interface is intuitive, providing easy access to all the available tools and enabling you to configure the tabbed panes layout.

You can write, test and debug code interactively using the the source code editor. It features syntax coloring and brace matching, automatic indentation, comment insertion, line numbering, syntax highlighting, auto-completion and clipboard history support. All these characteristics are designed to simplify your work, understand the document structure and identify errors easier.

DrJava enables you to work with multiple documents simultaneously and quickly switch between them. It comes with advanced search and navigation tools, as well as a bookmark manager.

The application can run a document as an applet and includes a handy interaction management tool, which helps you view classpaths and list the current interactions to definitions. Once your projects are finished, you can test it and use the built-in Eclipse compiler to generate the output.

Regular expression support, notifications, remote control, a source level debugger are other advantages that this application comes with. It provides support for the JUnit framework, enabling you to run unit tests.

The interface appearance is fully customizable, as you can change the theme, the toolbar buttons look, the colors and the window positions.

DrJava is a lightweight Java IDE that can combine ease of use with powerful development tools, in order to provide a simple environment for learning introductory programming.
