problems with parsing a string into int,

    public static void main(String[] args) throws IOException {

        String firstSlot,
               secondSlot,
               thirdSlot;
        
        int firstPiece,

        int coins = Integer.parseInt(br.readLine());

        System.out.print("\n");

        while (coins != 0) {

            System.out.print("Bet(Max: 1 - 4 Coins): ");
            int bet = Integer.parseInt(br.readLine());

            firstPiece = (int) Math.floor(Math.random() * MAX_PIECES) + 1;

                case 2: firstSlot = "CHERRY"; break;
                case 3: firstSlot = "GRAPE"; break;
                case 4: firstSlot = "------"; break;

                // just in case, there is still an option
                default: firstSlot = "------"; break;
            }

            switch (secondPiece) {

                case 1: secondSlot = "BELL"; break;

                default: secondSlot = "------"; break;
            }

            switch (thirdPiece) {

                case 1: thirdSlot = "BELL"; break;
                case 2: thirdSlot = "CHERRY";; break;
                case 3: thirdSlot = "GRAPE"; break;
                case 4: thirdSlot = "------"; break;

                // just in case, there is still an option
                default: thirdSlot = "------"; break;
            }

            if (firstSlot.equals("BELL") && secondSlot.equals("BELL") && thirdSlot.equals("BELL")) {

                System.out.println("Lucky One!");
            }

            System.out.print("\n");
            System.out.format("%2d %10s %10s %10s", firstSlot, secondSlot, thirdSlot);
            System.out.print("\n\n");

            coins = coins - bet;
        } // end of while loop
    }
}

output:

Enter The Coins: 50

Bet(Max: 1 - 4 Coins): Bet(Max: 1 - 4 Coins):

In

    System.out.format("%2d %10s %10s %10s", firstSlot, secondSlot, thirdSlot);

You pass three arguments but have 4 format specifiers.
