Java – use system exit(0)

public class WrapperTest {

public class WrapperTest {
    static {
        print(10);
    }

    static void print(int x) {
        System.out.println(x);
        System.exit(0);
    }
}

In the above code, system Exit (0) is used to stop the program What parameters does the method take? Why do we take it as 0 Can anyone explain this concept?
