Depending on the operating system, the exit value can be examined by the parent process that started the JVM. For example, if you started a java process via Runtime.exec(...), you can determine the exit value via Process.exitValue(). In windows batch-files, you can use the ERRORLEVEL function to change flow depending on the exit value. In Ant-Scripts, you can use the failonerror attribute in java-tasks to create a failed build when the exit value is not zero. There are many other examples...

Kumar, the System.exit() method does one thing: it makes the following invocation: Runtime.getRuntime().exit(status); Now please, don't ask what that statement does. If you really want to know, open up the $java/src.jar (see note below) and trace through the code yourself. It will be a good learning experience for you.
