java - 如何以新值退出 while 循环？

Question

对于我的一项作业，我们应该首先生成一个 1 到 13 之间的随机数字，然后我们询问用户是否愿意抽取另一个数字。如果他们这样做，我们应该在 1-13 范围内添加另一个随机数，而不超过 21。我所坚持的是如何在添加 1 个新随机数后退出 while 循环，并询问用户是否要添加另一个随机数。我尝试使用中断；这是我到目前为止所拥有的:

int randCard = 1 + (int) (Math.random() * ((13 - 1) + 1));
    int playerHand = 0 + randCard;
    System.out.println("START GAME #" + gameNum);
    System.out.println("Your card is a " + randCard + "!");
    System.out.println("Your hand is: " + playerHand);
    System.out.println("\n1. Get another card");
    System.out.println("2. Hold hand");
    System.out.println("3. Print statistics");
    System.out.println("4. Exit");
    System.out.print("\nChoose an Option: ");
    int selectedOption = menuOptions.nextInt();

 if (selectedOption == 1) {

             do {
                 int newRandCard = 1 + (int) (Math.random() * ((13 - 1) + 1));

                 System.out.println("Your card is a " + newRandCard + "!");
                 System.out.println("Your hand is: " + (playerHand + newRandCard));

                 playerHand = (playerHand + newRandCard);


                break;

             }
                 while (playerHand <= 21) ;

////////IDEALLY IT SHOULD PRINT LIKE THIS//////
Your card is a 4!
Your hand is: 4
1. Get another card
2. Hold hand
3. Print statistics
4. Exit
Choose an option: 1
Your card is a 9!
Your hand is: 13
1. Get another card
2. Hold hand
3. Print statistics
4. Exit

Answer 1

如果您只需要添加一次随机数，则再次为用户提供菜单选项

System.out.println("START GAME #" + gameNum);
int randCard = 1 + (int) (Math.random() * ((13 - 1) + 1));
System.out.println("Your card is a " + randCard + "!");
int playerHand = 0 + randCard;
System.out.println("Your hand is: " + playerHand);
do {
  System.out.println("1. Get another card");
  System.out.println("2. Hold hand");
  System.out.println("3. Print statistics");
  System.out.println("4. Exit");
  System.out.println("Choose an Option: ");
  int selectedOption = menuOptions.nextInt();

  if (selectedOption == 1) {
      randCard = 1 + (int) (Math.random() * ((13 - 1) + 1));
      System.out.println("Your card is a " + newRandCard + "!");
      System.out.println("Your hand is: " + (playerHand + newRandCard));
      playerHand = (playerHand + randCard);
  }
   ...other options to select
} while (playerHand <= 21) ;
