java多线程swing龟兔赛跑

以下是一个使用Java多线程实现的Swing龟兔赛跑的例子：

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

public class Race extends JFrame {
    private JLabel rabbitLabel;
    private JLabel turtleLabel;
    private JButton startButton;

    public Race() {
        setTitle("龟兔赛跑");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 200);
        setLayout(new FlowLayout());

        rabbitLabel = new JLabel(new ImageIcon("rabbit.png"));
        turtleLabel = new JLabel(new ImageIcon("turtle.png"));
        startButton = new JButton("开始赛跑");

        startButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                startRace();
            }
        });

        add(rabbitLabel);
        add(turtleLabel);
        add(startButton);
    }

    private void startRace() {
        Thread rabbitThread = new Thread(new Runnable() {
            @Override
            public void run() {
                for (int i = 0; i <= 100; i += 10) {
                    rabbitLabel.setLocation(i, rabbitLabel.getY());
                    try {
                        Thread.sleep(100);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
                JOptionPane.showMessageDialog(null, "兔子赢了！");
            }
        });

        Thread turtleThread = new Thread(new Runnable() {
            @Override
            public void run() {
                for (int i = 0; i <= 100; i += 5) {
                    turtleLabel.setLocation(i, turtleLabel.getY());
                    try {
                        Thread.sleep(200);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
                JOptionPane.showMessageDialog(null, "乌龟赢了！");
            }
        });

        rabbitThread.start();
        turtleThread.start();
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                Race race = new Race();
                race.setVisible(true);
            }
        });
    }
}

这个例子使用了Java的Swing库来创建一个窗口，其中包含了兔子和乌龟的图片以及一个开始赛跑的按钮。当点击开始赛跑按钮时，会创建两个线程分别控制兔子和乌龟的移动。每个线程都会在一定的时间间隔内移动对应的图片，直到达到终点位置。当其中一个线程到达终点时，会弹出一个对话框显示谁赢了。
