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 ");
}}}} 0 def 1
2 1 0 def 1
2 1 0 def def
2 1 0 def 1 def 1
Explanation:
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).
