Friday, November 30th, 2007Chapter 28 . Programming Environments and Interfaces 765 Figure 28-1: The Eclipse IDE. The code editor view in the center of the screen shows the code for the HelloWorld .java program. Although it isn t visible in the black-and-white figure produced for this book, the code editor performs on-the-fly syntax highlight using color and fontstyle changes. Java keywords are purple; plain comments appear in green; javadocstyle comments appear in a pale blue; strings are colored blue; and normal code is black. The right side of Eclipse displays another feature common among IDEs, a class browser. Class browsers enable developers to see the structure of their programs from the point of view of the code modules that make up the program rather than as mere files in a directory. This feature is not terribly useful for a small program such as HelloWorld.java, but larger programs that consist of dozens of classes or code modules are much easier to navigate using a code or class browser. The bottom of the screen shows various information and status windows. For example, the Problems view shows problems that might have occurred while compiling the program. Eclipse, like many other IDEs, allows you to double-click on an error in the Problems view to jump right to the error in the associated code file (see Figure 28-2).
