What happens when this Java program is executed? class IntRef { final int n; = n; n; } IntRef (int n) (this.n= } class C ( IntRef r; C (IntRef r) { this.r = r; } } public class Foo ( static void f (C c) { } c.r = new IntRef (c.r.n * 3); public static void main(String[] args) {\ Int Ref = new IntRef (2); C c = new C (s); f (c); System.out.println (s.n c.r.n);
