Java的hang子手如何累计添加字母

Question

我正在写一个Java hang子手游戏，到目前为止我已经得到了代码来一次替换一个。我需要的是每次都要替换，直到这个词被猜出。下面是它如何工作的一次一个：

 for(int i = 0; i < GuessWord.length(); i++) { 
     foundword = words[randvalue].replaceAll("[^" + xletters + "]", "_ "); 
     } 
      GuessedLetters = xletters.toString().toUpperCase(); 
      WordLabel.setText(foundword.toUpperCase()); 
      GuessedLabel.setText(GuessedLetters); 
      GuessText.setText(null); 
      GuessText.requestFocusInWindow(); 

这是我的，没有工作这么好其他的尝试：

 //replace underscores with letters as they are guessed while the word is not solved 
     do { 
     foundword = words[randvalue].replaceAll("[^" + xletters + "]", "_ "); 
     } 
     while (!SetMain.equals(GuessWord)); 
      //set results to labels 
      WordLabel.setText(foundword.toUpperCase()); 
      GuessedLabel.setText(GuessedLetters); 
      GuessText.setText(null); 
      GuessText.requestFocusInWindow(); 

这是我的全部代码为那些谁需要它：

import java.util.Random; 
    import java.util.Scanner; 
    import javax.swing.JOptionPane; 

    public class MainFrame extends javax.swing.JFrame { 

     public MainFrame() { 
      initComponents(); 
     } 
    static String SecretWord = ""; 
    double Result = 0; 
    StringBuilder mainword = new StringBuilder(); 
    String[] words = {"technology", "computer", "camera", "graphic design", "digital", "media", "technician", "photography", "troubleshoot", "pixels", "application", "download"}; 
    Random r = new Random(); 
    int randvalue = r.nextInt(11); 
    String GuessWord = words[randvalue]; 
    int errors = 0; 

     private void GoButtonActionPerformed(java.awt.event.ActionEvent evt) {           

     for(int i = 0; i < GuessWord.length(); i++) { 
      mainword.append("_ "); 
     } 
      mainword.append(SecretWord); 
      String SetMain = mainword.toString(); 
      WordLabel.setText(SetMain); 
      GuessButton.setEnabled(true); 
      GoButton.setEnabled(false); 
     }           

     private void GuessButtonActionPerformed(java.awt.event.ActionEvent evt){            
     String strGuess = GuessText.getText(); //user input 
     StringBuilder xletters = new StringBuilder(strGuess); // letters guessed 
     String GuessedLetters = null; 
     String foundword = null; 

     //replace underscores with letters as they are guessed 
     for(int i = 0; i < GuessWord.length(); i++) { 
     foundword = words[randvalue].replaceAll("[^" + xletters + "]", "_ "); 

     } 
      //set to labels to display results 
      GuessedLetters = xletters.toString().toUpperCase(); 
      WordLabel.setText(foundword.toUpperCase()); 
      GuessedLabel.setText(GuessedLetters); 
      GuessText.setText(null); 
      GuessText.requestFocusInWindow(); 

所以我希望代码能够累积取代字母，也就是说，如果这话您好：

硒CRET字：_ _ _ _ _ 猜到è....

密语：_é_ _ _ 猜到Ø....

密语：_é_Ø 猜中的。 ...

密语：_é_Ø 猜^ h ....

塞里特词：他_Ø 猜到升....

密语：你好 恭喜！

我需要这个在Netbeans IDE 7.2中工作，它必须为JLayeredPane工作，而不是System.out.print方法。谢谢！

我不知道，如果这entirly你之后，但它可能给你一些想法...

public class TestHangMan { 

    public static void main(String[] args) { 
     new TestHangMan(); 
    } 

    public TestHangMan() { 
     String word = "Testing"; 
     String mask = "_______"; 

     mask = checkGuess(word, mask, 'a'); 
     System.out.println(mask); 
     mask = checkGuess(word, mask, 't'); 
     System.out.println(mask); 
     mask = checkGuess(word, mask, 'e'); 
     System.out.println(mask); 
     mask = checkGuess(word, mask, 's'); 
     System.out.println(mask); 
     mask = checkGuess(word, mask, 'g'); 
     System.out.println(mask); 
     mask = checkGuess(word, mask, 'n'); 
     System.out.println(mask); 
     mask = checkGuess(word, mask, 'i'); 
     System.out.println(mask); 
    } 

    protected String checkGuess(String word, String mask, char guess) { 
     guess = Character.toLowerCase(guess); 
     StringBuilder sb = new StringBuilder(mask); 
     for(int index = 0; index < word.length(); index++) { 
      if (Character.toLowerCase(word.charAt(index)) == guess) { 
       sb.setCharAt(index, word.charAt(index)); 
      } 
     } 
     return sb.toString(); 
    } 

} 

将会产生...

_______ 
T__t___ 
Te_t___ 
Test___ 
Test__g 
Test_ng 
Testing 

您可以检查掩码，看看用户是否已经通过简单的使用mask.toLowerCase().contains(stringGuess.toLowerCase())

希望它有帮助。
