Looping a switch/case and adding a variable each time

-----------------------------------

This is the portion of code that I'm having trouble with
[code]System.out.println("Your starting hand is: " + playerCard1 + " + " + playerCard2);
    playerHand = playerCard1 + playerCard2;
    System.out.println("Press 1 to hit, press 2 to fold, press 3 to stay");
    action = input.nextInt();
    switch (action) {
    case 1: playerCard3 = (cards.nextInt(9+1)); playerHand = playerHand + playerCard1 + playerCard2 + playerCard3; System.out.println("You were dealt: " + playerCard3); break;
    case 2: System.out.println("You lose!"); break;
    case 3: break;[/code]
This is my Blackjack game, what I want to do is loop the options and the switch and case. I want to create an i variable, and re-write case 1 as something like
[code]case 1: i++; playerCardi = (cards.nextInt(9+1)); playerHand = playerHand + playerCard1 + playerCard2 + playerCardi; System.out.println("You were dealt: " + playerCardi); break;[/code]
In addition, I need a way to add another + playerCardi every time the player chooses to hit. How would I do this? (All the variables have already been declared)

I'm not sure what you mean looping cases? You would just construct it as any other loop.

If you can give more information to exactly what your attempting to do maybe I could help more :)

[code]
public class CaseLoop {
    
    public static void main(String args[]) {
        
        int loopTimes = 5;
        
        do {
            switch (getInput(loopTimes)) {
                case 0 : System.out.println("Case ZERO is EVEN @ "+loopTimes);
                    break;
                case 1 : System.out.println("Case 1 is ODD! @ "+loopTimes);
                    break;
                default: System.out.println("Defaults are good!");
                    break;
            }
            loopTimes--;
        }while (loopTimes > 0) ;
    }
    
    public static int getInput (int loopLeft) {
            return loopLeft % 2;
        }
}
[/code]
