System.exit and return.

[dmjpro]

Have a look at my code.

clas MainClass{
public static void main(String a[]){
 int a = 10;
 if(a==10) System.exit(0);
}
}

2nd version....

clas MainClass{
public static void main(String a[]){
 int a = 10;
 if(a==10) return;
}
}

When you run a class file using JVM then JVM starts up and automatically shuts down when main method terminates. Here in both cases at line 4 the main method terminates. So here return & System.exit doing same thing?

return stops the execution of the current method. If that method is the main method then the program exits. I would have expected that to be rather obvious to you.

Ah .............. Actually only the main method stuck to my mind. I didn't consider the usage of return in another methods;)
