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 ');
            }
        }
    }
}
