使用Swing在Java中创建MasterMind

Question

我是Java的初学者，正在为项目创建游戏。我正在使用Swing创建一个MasterMind版本。

这是我到目前为止有：

package GUI; 

import java.awt.GridLayout; 
import java.awt.event.*; 
import javax.swing.*; 


public class GUIMasterMind implements ActionListener { 
JFrame frame; 
JPanel contentPane; 
JLabel label, prompt, show, blackPegs, whitePegs; 
JButton step, newGame; 
JTextField guessBox; 
private String[] args; 
int guess; 

public GUIMasterMind() { 

    //frame created 
    frame = new JFrame("MasterMind:"); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

    // content pane 
    contentPane = new JPanel();  
    contentPane.setLayout(new GridLayout(0, 2, 10, 5)); 
    contentPane.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10)); 


    prompt = new JLabel("Enter a guess: "); 
    contentPane.add(prompt); 

    guessBox = new JTextField(); 
    guessBox.addActionListener(this); 
    contentPane.add(guessBox); 

    newGame = new JButton("New Game"); 
    newGame.setActionCommand("New Game"); 
    newGame.addActionListener(this); 
    contentPane.add(newGame); 

    step = new JButton("Compare"); 
    step.setActionCommand("Compare"); 
    step.addActionListener(this); 
    contentPane.add(step); 

    show = new JLabel("Results"); 
    contentPane.add(show); 

    blackPegs = new JLabel("Black Pegs: "); 
    contentPane.add(blackPegs); 

    whitePegs = new JLabel("White Pegs: "); 
    contentPane.add(whitePegs); 

    frame.setContentPane(contentPane); 

    frame.pack(); 
    frame.setVisible(true); 


} 

public void actionPerformed(ActionEvent event){ 
    String eventName = event.getActionCommand(); 

    String g1 = guessBox.getText(); 

    if(eventName.equals("New Game")){ 
     GUIMasterMind.main(args); 
    } 
    else if(eventName.equals("Compare")){ 


     String[] guess = new String[4]; 

     for (int i = 0; i < guess.length; i++) { 
      guess[i] = g1.substring(i, i+1); 
      System.out.println(guess[i]); 
     } 

     MMCode MM = new MMCode(guess); 
     show.setText("This was your guess: "+ MM.toHTML()); 

     if(MM.compareTo() == 1){ 
      System.out.println("If you would like to start a new game press the button!"); 
     } 
     else if(MM.compareTo() == 0){ 
      prompt.setText("Guesses remaining: "); 
     } 
     else { 
      prompt.setText("Error"); 
     } 
     guessBox.setText(""); 
     System.out.println("done"); 
     } 
} 


public static void main(String[] args) { 
    javax.swing.SwingUtilities.invokeLater(new Runnable(){ 
     public void run(){ 
      GUIMasterMind game = new GUIMasterMind(); 
     } 
    }); 
} 
} 

目前，当我的游戏运行我有用户输入一个代码和代码是相对于计算机本身生成的代码。然而，我的问题是在actionPerformed（）方法中。我希望这段代码能够保持重新运行而不必创建全新的密码。我尝试过各种循环，但没有成功。任何帮助，将不胜感激。

此外，您可能会忽略白色/黑色挂钩代码，稍后我会解决。我只想让我的程序首先正确运行。这是我的另一堂课。这个类的目的是比较两个数组，猜测和秘密。

package GUI; 


public class MMCode { 
String[] guess = new String[4]; 
String[] secret = new String[4]; 
int num; 

public MMCode(String[] guessess){ 
    for (int i = 0; i < guess.length; i++) { 
     this.guess[i] = guessess[i]; 
    } 

    setSecret(); 

} 

public void setSecret(){ 
    for (int i = 0; i < secret.length; i++) { 
     num = ((int)(Math.random()*6+1)); 
     secret[i] = Integer.toString(num); 
    } 
} 

public String getSecret(){ 
    return ("The secret code is: "+secret[0]+secret[1]+secret[2]+secret[3]); 
} 

public void setGuess(){ 

} 

public String getGuess(){ 
    return ("Your guess is:  "+guess); 
} 

public int compareTo(){ 

    if(guess[0].equals(secret[0]) && guess[1].equals(secret[1]) && guess[2].equals(secret[2]) && guess[3].equals(secret[3])){ 
     System.out.println("Congratulations you've guessed the computer's code!"); 
     return 1; 
    } else if (!(guess[0].equals(secret[0]) && guess[1].equals(secret[1]) && guess[2].equals(secret[2]) && guess[3].equals(secret[3]))){ 
     return 0; 
    } 
    return -1; 
} 

public String toHTML(){ 
    String html = ""; 


    html += guess[0].toString(); 
    html += guess[1].toString(); 
    html += guess[2].toString(); 
    html += guess[3].toString(); 
    return html; 
} 

}

开始通过改变MMCode的构造函数，因此它并不需要猜测...

public MMCode(){ 
    setSecret(); 
} 

添加一个名为setGuess新的方法，例如...

public void setGuess(String[] guessess){ 
    for (int i = 0; i < guess.length; i++) { 
     this.guess[i] = guessess[i]; 
    } 
} 

从actionPeformed方法取MMCode MM = new MMCode(guess);并使其成为实例变量

public class GUIMasterMind implements ActionListener { 
    //... 
    private MMCode mmCode; 
    //... 
    public GUIMasterMind() { 
     //... 
     mmCode = new MMCode(); 
     //... 

然后在actionPerformed方法，你只需要更新的MMCode实例...

public void actionPerformed(ActionEvent event){ 
    //... 
    else if(eventName.equals("Compare")){ 
     String[] guess = new String[4]; 

     for (int i = 0; i < guess.length; i++) { 
      guess[i] = g1.substring(i, i+1); 
      System.out.println(guess[i]); 
     } 

     mmCode.setGuess(guess); 
     //...
