Question

我正在为一个玩家和计算机正在玩游戏的课程编写程序。游戏包括挑选1,2,3或4个火柴棍。玩家从21输掉最后一根棍子。游戏被操纵，以便计算机永远胜利。

无论如何，我的问题在于结束游戏的逻辑。这是我的代码：

 public static void main(String[] args) {
    Scanner keyboard = new Scanner(System.in);
    String player;
    int matchstick;
    int total = 0;

    System.out.println("Rules of the game: \nThe player and computer take turns picking 1, 2, 3 , or 4 matchsticks."
                        + " \nThe player to pick the last stick out of 21 loses.");
    System.out.print("\nHello player. Please enter your name: ");
    player = keyboard.next();

     while (total < 21) {

        System.out.print("\nHow many matchsticks do you pick, " + player + "? ");
        matchstick = keyboard.nextInt();

        while (matchstick > 4) {
            System.out.print("You have exceeded the limit of 4 matchsticks. Please try again. \n\nHow many matchsticks do you pick? ");
            matchstick = keyboard.nextInt();
        }

        total += matchstick;

        System.out.println(player + " has picked " + matchstick + " matchstick(s) and brings the total to " + total + " matchsticks.");

        if (total == 21) {
            System.out.println("You picked the last matchstick... YOU LOSE!!!");
        }

        System.out.println("\nNow it's the computer's turn.");

        if (matchstick == 1) {
            total += 4;
            System.out.println("The computer chooses 4 matchsticks, bringing the total to " + total + " matchsticks.");
        }
        if (matchstick == 2) {
            total += 3;
            System.out.println("The computer chooses 3 matchsticks, bringing the total to " + total + " matchsticks.");
        }
        if (matchstick == 3) {
            total += 2;
            System.out.println("The computer chooses 2 matchsticks, bringing the total to " + total + " matchsticks.");
        }
        if (matchstick == 4) {
            total += 1;
            System.out.println("The computer chooses 1 matchstick, bringing the total to " + total + " matchsticks.");
        }

    }

}

}

当while循环的条件（总计<21）为假时，如何在System.out.println之后跳过这些行（＆＃34;你选择了最后一根火柴......你丢了!! ！＆＃34）;？在条件满足后有没有办法打破中间循环？或者我的逻辑是完全错误的？

Answer 1

您可以从方法return

中main

  ...
if (total == 21) {
     System.out.println("You picked the last matchstick... YOU LOSE!!!");
     return;
}
  ...

Answer 2

你的逻辑完全错了.bcz已经让你的电脑选择了根据玩家值的值。每次都由玩家开始。所以每次玩家选择一个值然后计算机。每次总时间= 5。

{!terms f=uniqueId}1000,1001,10002,10003

然后玩家必须玩。所以玩家每次都会失败。

当while循环的条件（总计<21）为假时？试试这个。

ex: player play 4 times + computer play 4 times : total =20

但计算机永远胜利
