java - Hangman While 循环解决方案

Question

 import java.util.*;
 public class Hangman 
 {
 public static void main(String[] args) 
 {
    Scanner kybd = new Scanner(System.in);
    System.out.println("Please enter word: ");
    String Word = kybd.nextLine();
    String dashWord = Word.replaceAll(".", "-");
    System.out.println(dashWord);

    StringBuilder dashWordB = new StringBuilder(dashWord);

    System.out.println("Please guess a letter: ");
    char letterGuess = kybd.next().charAt(0);
    int lettersGuessed = 0;

// While loop should exit once letterGuessed is equal to Word.length()

 while (lettersGuessed <= Word.length()){
       for (int i=0; i < Word.length(); i++)
    {

       if (Word.charAt(i) == letterGuess)
            {
            dashWordB.setCharAt(i,letterGuess);
            lettersGuessed++;
            System.out.println("letters guessed: " + lettersGuessed);
                System.out.println("word length: " + Word.length());
            }
       if (i == Word.length() - 1)
       {
           i = -1;
           System.out.println(dashWordB);
           System.out.println("Have another guess: ");
           letterGuess = kybd.next().charAt(0);
        }

     }
 }
    System.out.println(dashWordB);
    System.out.println(lettersGuessed);

   }          
 }

当 dashWordB 的所有字母都被正确猜出时，退出 while 循环时遇到问题。非常感谢任何帮助。

只需在 while 循环中添加以下内容:

if(lettersGuessed == Word.length()){
    break;
}

这应该可以帮助您解决问题。

另外，按照其他人的建议，将 while 条件更改为以下内容:

while (lettersGuessed < Word.length())

所以你的 while 循环应该如下:

while (lettersGuessed < Word.length()){
        for (int i=0; i < Word.length(); i++)
        {

            if (Word.charAt(i) == letterGuess)
            {
                dashWordB.setCharAt(i,letterGuess);
                lettersGuessed++;
                System.out.println("letters guessed: " + lettersGuessed);
                System.out.println("word length: " + Word.length());
            }
            if (i == (Word.length() - 1))
            {
                i = -1;
                System.out.println(dashWordB);
                System.out.println("Have another guess: ");
                letterGuess = kybd.next().charAt(0);
            }

            if(lettersGuessed == Word.length()){
                break;
            }

        }
    }
