java - System.out.print不断循环错误

Question

大家好，我一直在尝试帮助我的 friend 使用这段几乎可以工作的代码。这是一个简单的二十一点游戏，询问用户是否想要另一张牌，写"is"，如果用户写“否”，那么他的回合结束，应该轮到庄家了。我遇到的问题是，当我写“否”来结束我的回合时，它只是不断询问我是否需要在控制台中添加另一张卡。谢谢你的帮助。例如。

Another Card (yes/no)?: nO
Another Card (yes/no)?: no
Another Card (yes/no)?: no
Another Card (yes/no)?: no
Another Card (yes/no)?: nO
Another Card (yes/no)?: no

这是我的代码:

while (playing == true ){
        System.out.print("Another Card (yes/no)?: ");
        anotherCard = keyboard.nextLine(); 


        if (anotherCard.equals("yes")) {

            nextCard = random.nextInt(10) + 1;
            cardTotal += nextCard;
            System.out.println("Card: " + nextCard);
            System.out.println("Total: " + cardTotal);

            if (cardTotal > 21) {               
            System.out.println("You busted, Dealer Wins"); 
            playing = false;       
            }  
            if (cardTotal == 21) {
            System.out.println("Player Wins"); 
            playing = false;
            }

            } 
           if (anotherCard.equals("no")) {
           dealerturn = true;

           if ((dealerturn == true) && (dTotal < 17)) {                           
                nextCard = random.nextInt(10) + 1;
                dTotal += nextCard;

                if (dTotal > 21) {                  
                System.out.println("Dealer Busts, You Win!");
                playing = false;

                }
            }
            else if ((dealerturn == true) && (dTotal > 17))  {
             if (dTotal > 21) {                  
                System.out.println("Dealer Busts, You Win!");
                playing = false;                       
                }
             }
           }
        }
     }

这是因为当用户不想玩时，您没有将 playing 更改为包含 false:

if (anotherCard.equals("yes")) {
    ...
} else { // you should add this case:
    playing = false;
}
