why main returns nothing always in java

[David O'Meara]

Compared to C?

[Jesper de Jong]

Because that's how the people who invented Java made it...

If you need to return a return value to the operating system (so that you can use it in for example a batch file or shell script), use System.exit(n); to end your Java program (where n is the return code).

[Rob Spoor]

In C and C++, the return value of the main method can be used by the calling shell (e.g. bash). In Java, you use System.exit to give this value back to the calling shell.
