The parameter in System.exit(status) is just a status. The value of it doesn't afeect anything. By convention, if you set it to non-zer, it means abnormal termination. Eugene Kononov.

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...

We used the exit value in korn shell scripts to conrol email notifications for failed processes.
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.
