用java写一个打地鼠游戏

以下是一个简单的打地鼠游戏Java实现：

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

public class WhackAMole extends JFrame implements ActionListener {
    private final int ROWS = 5;
    private final int COLS = 5;
    private final int NUM_MOLES = 10;
    private final int TIME_LIMIT = 30;
    private JButton[][] buttons;
    private Timer timer;
    private JLabel scoreLabel;
    private int score;
    private int molesLeft;
    private int timeLeft;

    public WhackAMole() {
        super("Whack-A-Mole");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new BorderLayout());

        JPanel buttonPanel = new JPanel();
        buttonPanel.setLayout(new GridLayout(ROWS, COLS));
        buttons = new JButton[ROWS][COLS];
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                buttons[i][j] = new JButton("");
                buttons[i][j].setActionCommand(i + " " + j);
                buttons[i][j].addActionListener(this);
                buttonPanel.add(buttons[i][j]);
            }
        }

        add(buttonPanel, BorderLayout.CENTER);

        JPanel infoPanel = new JPanel();
        infoPanel.setLayout(new GridLayout(1, 2));
        scoreLabel = new JLabel("Score: 0");
        infoPanel.add(scoreLabel);
        JLabel timeLabel = new JLabel("Time Left: " + TIME_LIMIT);
        infoPanel.add(timeLabel);

        add(infoPanel, BorderLayout.SOUTH);

        pack();
        setLocationRelativeTo(null);
        setVisible(true);

        timer = new Timer(1000, new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                timeLeft--;
                timeLabel.setText("Time Left: " + timeLeft);
                if (timeLeft == 0) {
                    timer.stop();
                    JOptionPane.showMessageDialog(WhackAMole.this, "Game over! Your score is " + score);
                }
            }
        });

        startGame();
    }

    private void startGame() {
        score = 0;
        molesLeft = NUM_MOLES;
        timeLeft = TIME_LIMIT;
        scoreLabel.setText("Score: " + score);
        timer.restart();
        for (int i = 0; i < ROWS; i++) {
            for (int j = 0; j < COLS; j++) {
                buttons[i][j].setEnabled(true);
                buttons[i][j].setText("");
            }
        }
        Random rand = new Random();
        for (int i = 0; i < NUM_MOLES; i++) {
            int row, col;
            do {
                row = rand.nextInt(ROWS);
                col = rand.nextInt(COLS);
            } while (!buttons[row][col].getText().equals(""));
            buttons[row][col].setText("M");
        }
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        String[] tokens = e.getActionCommand().split(" ");
        int row = Integer.parseInt(tokens[0]);
        int col = Integer.parseInt(tokens[1]);
        if (buttons[row][col].getText().equals("M")) {
            buttons[row][col].setText("");
            score++;
            molesLeft--;
            scoreLabel.setText("Score: " + score);
            if (molesLeft == 0) {
                timer.stop();
                JOptionPane.showMessageDialog(this, "You win! Your score is " + score);
            }
        } else {
            score--;
            scoreLabel.setText("Score: " + score);
        }
    }

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

这个游戏界面由一个5x5的按钮网格和一个显示得分和剩余时间的信息面板组成。游戏开始后，随机生成10只地鼠，每只地鼠随机出现在一个按钮上。玩家需要尽可能快地点击出现的地鼠，每击中一只得1分，错过一只扣1分。游戏时间为30秒，时间到后游戏结束，得分高者获胜。
