Introduction This tutorial is for students who are currently taking a Java course that uses Eclipse and for Java programmers who want to develop Java projects using Eclipse. Eclipse is an open source supported by IBM. You can use JDK command line utility to write Java programs. The JDK command line utility consists of a set of separate programs, such as compiler and interpreter, each of which is invoked from a command line. Besides the JDK command line utility, there are more than a dozen Java development tools on the market today, including Borland JBuilder, NetBeans, Sun ONE Studio (a commercial version of NetBeans), Eclipse, and WebGain Visual Café. These tools support an integrated development environment (IDE) for rapidly developing Java programs. Editing, compiling, building, debugging, and online help are integrated in one graphical user interface. Using these tools effectively will greatly increase your programming productivity. This brief tutorial will help you to become familiar with Eclipse. Specifically, you will learn how to create projects, create programs, compile, and run programs.
