Doubt:control flow working

public class Rainbow {
2.       public static void main(String[] args) {
3.           int count = 0;
4.           String[] colours = {"red", "orange", "yellow", "green",
5.               "blue",  "indigo", "violet"};
6.           start: for (int i = 0; i < 5; i++) {
7.               switch (i) {
8.                   case 0:
9.                       count--;
10.                      break;
11.                  case 3:
12.                      continue start;
13.                  case 4:
14.                      count--;
15.                  break start;
16.                  default:
17.                      count++;
18.                  break;
19.              } // switch end
20.              count++;
21.          }
22.      System.out.println(colours[count]);
23.     }
24.  }
1.	Standard output will display 'red'. 
2.	Standard output will display 'green'. 
3.	Standard output will display 'indigo'. 
4.	Standard output will display 'violet'. 
5.	An ArrayIndexOutOfBoundsException will be thrown, halting the program.

can some please explain the working of this code?

thanks,
Piya

Actually the output what iam geting is
Green

and my explanation is dat

while your i becomes 3 continue from start...but at that time i will remain 3 won't reinitialize and it becomes
4 because of i++
then count becomes 3 and break start means control will leave out of the iterator..i mean control will go to the code just after that for loop..

now it will print the colours[3] and its green

I hope you are not trying to tell us that labelled continue is good programming practice.
