Can we call main method explicitly?

Question

public static void main is called by jvm.

Answer 1

It's a static method like any other, so once the program is executing you can call another main method using a static call (i.e. Class.main() )

Answer 2

public class Program
{
static int x = 0;
public static void main(String[] args) {
if (x < 20) {
x++;
main(args);
} else
System.out.println(x);
}
}

Answer 3

Yes, anyone know how?
