Call stack

As you know, a very long stack may lead to StackOverflowError.

In this problem, you need to invoke a method to create the shortest stack. Your program should print "Hello" exactly three times.

public class MyClass {
    public static void main(String args[]) {
        // What to invoke here to get the shortest stack?
    }
    
    public static void f() {
        System.out.println("Hello!");
        q();
    }
    
    public static void g() {
        System.out.println("Hello!");
        System.out.println("Hello!");
        System.out.println("Hello!");
    }
    
    public static void h() {
        g();
    }
    
    public static void q() {
        System.out.println("Hello!");
        System.out.println("Hello!");
    }
}
