Hi, if the status argument of System.exit(int status) is a non-zero number,what does it mean?
As far as I know ,the non-zero argument here means abnormal exit,but is there specific meaning of different int arguments?

You can set different ints to mean different things in your *.bat file that called the java app. Traditionally zero indicates a successful exit with no errors while one indicates something went wrong and the program exited abnormally.

Most of the time (unless you're writing GUI stuff) you won't need to deal with System.exit at all.
