What will be the output of the program (in jdk1.6 or above)?

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');
    }
}
