What will be the output of the program?

for(int i = 0; i < 3; i++) 
{ 
    switch(i) 
    { 
        case 0: break; 
        case 1: System.out.print("one "); 
        case 2: System.out.print("two "); 
        case 3: System.out.print("three "); 
    } 
} 
System.out.println("done");

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");
    }
}
