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");
}
}
