What will be the output of the program?

class A 
{
    final public int GetResult(int a, int b) { return 0; } 
} 
class B extends A 
{ 
    public int GetResult(int a, int b) {return 1; } 
} 
public class Test 
{
    public static void main(String args[]) 
    { 
        B b = new B(); 
        System.out.println("x = " + b.GetResult(0, 1));  
    } 
}

class Super
{ 
    public int i = 0; 

    public Super(String text) /* Line 4 */
    {
        i = 1; 
    } 
} 

class Sub extends Super
{
    public Sub(String text)
    {
        i = 2; 
    } 

    public static void main(String args[])
    {
        Sub sub = new Sub("Hello"); 
        System.out.println(sub.i); 
    } 
}

public class BoolTest 
{
    public static void main(String [] args) 
    {
        Boolean b1 = new Boolean("false");
        boolean b2;
        b2 = b1.booleanValue();
        if (!b2) 
        {
            b2 = true;
            System.out.print("x ");
        }
        if (b1 & b2) /* Line 13 */
        {
            System.out.print("y ");
        }
        System.out.println("z");
    }
}
