Terminate program with letter Q

Question

I'd like to terminate the program by typing Q whenever. I can't place it in "diceChosen" because it's an integer. I've tried different things but nothing works for me.

Scanner userInput = new Scanner(System.in);

int wins = 0;
int losses = 0;

int diceOne = 0;
int diceTwo = 0;
int diceThree = 0;

int sum = 0;


System.out.println("Välkommen till spelet 12. Du ska slå 1-3 tärningar och försöka få summan 12...");



for (int counter = 0; counter < 3; counter++) {

    System.out.printf("%nAnge vilken tärning du vill slå[1,2,3](avsluta med q): ");

    int diceChosen = userInput.nextInt();

    if (diceChosen == 1)
        diceOne = (int)(Math.random() * 6) + 1;

    if (diceChosen == 2)
        diceTwo = (int)(Math.random() * 6) + 1;

    if (diceChosen == 3)
        diceThree = (int)(Math.random() * 6) + 1;

    sum = diceOne + diceTwo + diceThree;

    if (sum == 12)
        ++wins;

    if (sum > 12)
        ++losses;


    System.out.printf("%d %d %d sum: %d #vinst: %d #förlust: %d", diceOne, diceTwo, diceThree, sum, wins, losses);
}

Answer 1

Since you can not use try and catch other alternative can be by changing your userInput.nextInt() to userInput.nextLine(); so it can detect when Q is pressed if Q is not pressed then we convert String to int so it can calculate the logic with Integer.parseInt(diceChosen);

All the code

    while (true) {
            for (int counter = 0; counter < 3; counter++) {

                System.out.printf("%nAnge vilken tärning du vill slå[1,2,3](avsluta med q): ");


                String diceChosen = diceChosen = userInput.nextLine();
                int diceChosenToInteger = 0;
                if (diceChosen.equalsIgnoreCase("Q")) {
                    System.exit(0);
                } else {
                    diceChosenToInteger = Integer.parseInt(diceChosen);
                }


                if (diceChosenToInteger == 1)
                    diceOne = (int) (Math.random() * 6) + 1;

                if (diceChosenToInteger == 2)
                    diceTwo = (int) (Math.random() * 6) + 1;

                if (diceChosenToInteger == 3)
                    diceThree = (int) (Math.random() * 6) + 1;

                sum = diceOne + diceTwo + diceThree;

                if (sum == 12)
                    ++wins;

                if (sum > 12)
                    ++losses;


                System.out.printf("%d %d %d sum: %d #vinst: %d #förlust: %d", diceOne, diceTwo, diceThree, sum, wins, losses);


            }
        }

    }
   
}
