在正确回答4个连续问题后，您如何让用户选择退出程序？

Question

我试图让用户选择在他/她获得4个乘法问题后退出程序。如果他/她选择继续，我必须给他/她另一次机会退出每次。我希望这是有道理的..我发布的代码有效，但我觉得我必须改变一些东西才能让用户选择终止。

import java.security.SecureRandom; //program will use random numbers
import java.util.Scanner; //program will need user input

public class RandomMultiplication 
{
    public static void main(String[] args)
    {
        while(true)//continues to play game
        {
            question();
        }
    }

    public static void question()
    {
        boolean repeat = false;
        SecureRandom randomNumbers = new SecureRandom();
        //pick random numbers (1-9) for multiplication scenario
        int number1 = randomNumbers.nextInt(10); //first number
        int number2 = randomNumbers.nextInt(10); //second number

        while(!repeat)
        {
            int responseCode = randomNumbers.nextInt(4);
            if(multiplicationProblem(number1,number2))
            {
                switch(responseCode)
                {
                case 0: System.out.println("Very Good!");
                    break;
                case 1: System.out.println("Excellent!");
                    break;
                case 2: System.out.println("Keep up the good work!");
                    break;
                case 3: System.out.println("Nice work!");
                    break;
                }//ends switch
                repeat = true; //stops repeating the same question
            }//end if statement
            else
            {
                responseCode = randomNumbers.nextInt(4);
                switch(responseCode)
                {
                case 0: System.out.println("No. Please try again!");
                    break;
                case 1: System.out.println("Wrong, Try once more!");
                    break;
                case 2: System.out.println("Don't give up!");
                    break;
                case 3: System.out.println("No. Keep trying!");
                    break;
                }//ends switch

            }//ends else condition

        }//ends while loop
    }

    public static boolean multiplicationProblem(int number1, int number2)
    {
        Scanner input = new Scanner(System.in);
        int userInputAnswer;
        int correctCounter = 0;

        System.out.printf("How much is %d times %d?", number1, number2);
        userInputAnswer = input.nextInt();
        if (userInputAnswer == number1 * number2)
        {
            return true;
        }       
        else
        {
            return false;
        }
    }

}
