Question

每当我的用户正确猜到这个词时，我都无法弄清楚如何终止循环。

我可以做这样的事情，或者使用子字符串函数逐个取出单词的字母。

这是我到目前为止所做的：

package mcneil;

import java.util.Scanner;
import java.util.Random;

public class HangmanGame
{

public static void main(String[] args)
{
    Scanner ui = new Scanner(System.in);
    Random rnd = new Random();      
    String words[] = {"Mac", "Windows", "DOS", "Linux", "Solaris"};
    String man[] ={"  ______\n"
                 + "  |    |\n"
                 + "  |\n"
                 + "  |\n"
                 + "  |\n"
                 + "_____",

                   "  ______\n"
                 + "  |    |\n"
                 + "  |    O\n"
                 + "  |\n"
                 + "  |\n"
                 + "_____",

                   "  ______\n"
                 + "  |    |\n"
                 + "  |    O\n"
                 + "  |    |\n"
                 + "  |\n"
                 + "_____",

                   "  ______\n"
                 + "  |    |\n"
                 + "  |    O\n"
                 + "  |    |/\n"
                 + "  |\n"
                 + "_____",

                   "  ______\n"
                 + "  |    |\n"
                 + "  |    O\n"
                 + "  |   \\|/\n"
                 + "  |\n"
                 + "_____",

                   "  ______\n"
                 + "  |    |\n"
                 + "  |    O\n"
                 + "  |   \\|/\n"
                 + "  |   /\n"
                 + "_____",

                   "  ______\n"
                 + "  |    |\n"
                 + "  |    O\n"
                 + "  |   \\|/\n"
                 + "  |   / \\\n"
                 + "_____"};
    String guess;
    int guesses = 0;
    String guessedLetters = " ";

    boolean wordGuessed = false;

    System.out.println(man[0]);
    String answer = words[rnd.nextInt(words.length)];

    System.out.println("I'm thinking of a word that contains "
                        + answer.length() +  " letters\n");

    do
   {           
       for(char letter : answer.toCharArray())
       {
           if(guessedLetters.indexOf(letter)== -1)
           {
               System.out.print('*');
           }
           else
           {

               System.out.print(letter);
           }

       }
       System.out.println("\nPlease enter a letter: ");
       guess = ui.next();

       guessedLetters += guess + " ";

       System.out.println("You have guessed the letters: " 
               + guessedLetters);

       // not a good guess
       if(!answer.contains(guess))
       {
           System.out.println(man[guesses + 1]);
           guesses++;
           //some kind of counter
       }
       else {
       }if(answer.length() == 0)
       {
            wordGuessed = true;
       }
   }while(!wordGuessed && guesses < 6);            
    }    
}

您有条件表明单词中是否包含猜测，以及答案中的字母是否在猜测字母中。你需要一些跟踪答案是否完整的东西。也许你可以计算猜测答案的非*字母。或者还有其他方法。

如果有正确的用户输入（Hangman Game），如何摆脱循环？
