Flow Control - Programming

Q1:

What will be the output of the program? 
public class Switch2 
{
    final static short x = 2;
    public static int y = 0;
    public static void main(String [] args) 
    {
        for (int z=0; z < 4; z++) 
        {
            switch (z) 
            {
                case x: System.out.print('0 ');
                default: System.out.print('def ');
                case x-1: System.out.print('1 ');  
                            break;
                case x-2: System.out.print('2 ');
            }
        }
    }
}

A 0 def 1

B 2 1 0 def 1

C 2 1 0 def def

D 2 1 0 def 1 def 1

ANS:A - 0 def 1

When z == 0 , case x-2 is matched. When z == 1, case x-1 is matched and then the break occurs. When z == 2, case x, then default, then x-1 are all matched. When z == 3, default, then x-1 are matched. The rules for default are that it will fall through from above like any other case (for instance when z == 2), and that it will match when no other cases match (for instance when z==3).
