While循环永远重复打印语句时

Question

我正在制作一个Hangman游戏，用户可以猜测一种颜色。 我想发生的事情是：如果用户错误地获得了5个以上的错误（通过所有5条提示），它将表明该用户已丢失。 while循环结束后（单词正确或经过所有5条提示），它应该告诉您是否获胜。 这是执行此操作的代码部分：

public static void main(String[] args){
  Scanner in = new Scanner(System.in);
  String color = getColor();
  String result = EmptyStr(color);
  String[] hints = getHints(color);
  System.out.println("Please enter a letter:");
  char letter = in.next().charAt(0);
//-----------------------------------------------------------
  int wrong = 0;
  while (wrong<6){
    if (checkLetter(color, letter)){
      // result was previously defined elsewhere so don't worry about it
      result = Result(color, result, letter);
      System.out.println("Correct guess! here is your word so far: " + result);
      System.out.println("Lifelines left: " + (5 - wrong));
      if (result.equals(color)){
        System.out.println("congratulations! You Won!");
        break;
      }
    }
    else{
      wrong ++;
      System.out.println(hints[0]);
      System.out.println("Lifelines left: " + (5 - wrong));
    }
  }
  // also not sure what to put here after player wins or loses: System.out.println("Sorry! You lost! The correct word was: " + color);

}

但是，一旦我输入了一个字母并且正确无误， result = Result(color, result, letter); System.out.println("Correct guess! here is your word so far: " + result); System.out.println("Lifelines left: " + (5 - wrong)); result = Result(color, result, letter); System.out.println("Correct guess! here is your word so far: " + result); System.out.println("Lifelines left: " + (5 - wrong)); 永远重复。 我想知道：为什么它会永远重复？ 而且，我该如何对其进行修复？

Answer 1

我发现了自己的问题！

问题是，为了重申它并允许我重新输入一个字母， char letter = in.next().charAt(0); 必须在while循环内。 这解决了整个问题！

Answer 2

我想我看到了问题。 当用户正确猜对时，没有迭代，只有在错误猜对时才有迭代。 确保首先添加另一个“错误的++”。 那可能会解决问题。

if (checkLetter(color, letter)){
      // result was previously defined elsewhere so don't worry about it
      result = Result(color, result, letter);
      System.out.println("Correct guess! here is your word so far: " + result);
      System.out.println("Lifelines left: " + (5 - wrong));
      wrong ++;
