用JAVA写一个简单游戏

以下是一个简单的Java游戏示例，名称为“Whack-a-Mole”（打地鼠）：

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

public class WhackAMole extends JFrame implements ActionListener {
    private static final int NUM_BUTTONS = 9;
    private static final int GAME_TIME = 30;
    private JButton[] buttons;
    private int score;
    private JLabel scoreLabel;
    private Timer gameTimer;
    private int timeLeft;

    public WhackAMole() {
        setTitle("Whack-a-Mole");
        setSize(300, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new GridLayout(3, 3));
        buttons = new JButton[NUM_BUTTONS];
        for (int i = 0; i < NUM_BUTTONS; i++) {
            buttons[i] = new JButton(" ");
            buttons[i].setActionCommand(Integer.toString(i));
            buttons[i].addActionListener(this);
            add(buttons[i]);
        }
        score = 0;
        scoreLabel = new JLabel("Score: " + score);
        add(scoreLabel);
        gameTimer = new Timer(1000, new TimerListener());
        timeLeft = GAME_TIME;
        gameTimer.start();
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        int buttonIndex = Integer.parseInt(e.getActionCommand());
        if (buttons[buttonIndex].getText().equals("M")) {
            score++;
            scoreLabel.setText("Score: " + score);
        }
    }

    private class TimerListener implements ActionListener {
        public void actionPerformed(ActionEvent e) {
            timeLeft--;
            if (timeLeft == 0) {
                gameTimer.stop();
                JOptionPane.showMessageDialog(null, "Time's up! Final score: " + score);
                System.exit(0);
            } else {
                int randomIndex = (int) (Math.random() * NUM_BUTTONS);
                for (int i = 0; i < NUM_BUTTONS; i++) {
                    if (i == randomIndex) {
                        buttons[i].setText("M");
                    } else {
                        buttons[i].setText(" ");
                    }
                }
            }
        }
    }

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

这个游戏有9个按钮，每秒钟随机一个按钮上会出现一个“M”（地鼠），玩家需要在游戏时间内尽可能多地点击出现的地鼠，最后显示分数。
