java龟兔赛跑图形界面

以下是一个简单的Java GUI程序，用于模拟龟兔赛跑。它使用了Java Swing库来创建图形用户界面，并使用Java多线程来模拟比赛过程。

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

public class TurtleAndRabbitRace extends JFrame {
    private JLabel rabbitLabel, turtleLabel;
    private JButton startButton;
    private JPanel raceTrackPanel;
    private int rabbitPosition, turtlePosition;

    public TurtleAndRabbitRace() {
        setTitle("Turtle and Rabbit Race");
        setLayout(new BorderLayout());

        // 创建兔子和乌龟的标签
        rabbitLabel = new JLabel(new ImageIcon("rabbit.jpg"));
        turtleLabel = new JLabel(new ImageIcon("turtle.jpg"));

        // 将兔子和乌龟标签添加到赛道面板中
        raceTrackPanel = new JPanel();
        raceTrackPanel.setLayout(null);
        raceTrackPanel.setPreferredSize(new Dimension(800, 200));
        raceTrackPanel.add(rabbitLabel);
        raceTrackPanel.add(turtleLabel);
        rabbitLabel.setBounds(0, 0, 100, 100);
        turtleLabel.setBounds(0, 100, 100, 100);

        // 创建开始按钮
        startButton = new JButton("Start");
        startButton.addActionListener(e -> startRace());

        // 将赛道面板和开始按钮添加到主面板中
        add(raceTrackPanel, BorderLayout.CENTER);
        add(startButton, BorderLayout.SOUTH);

        pack();
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible(true);
    }

    private void startRace() {
        // 创建兔子和乌龟的线程
        Thread rabbitThread = new Thread(() -> {
            while (rabbitPosition < 700) {
                int distance = (int) (Math.random() * 10);
                rabbitPosition += distance;
                rabbitLabel.setLocation(rabbitPosition, 0);
                try {
                    Thread.sleep(100);
                } catch (InterruptedException ex) {
                    ex.printStackTrace();
                }
            }
        });

        Thread turtleThread = new Thread(() -> {
            while (turtlePosition < 700) {
                int distance = (int) (Math.random() * 5);
                turtlePosition += distance;
                turtleLabel.setLocation(turtlePosition, 100);
                try {
                    Thread.sleep(100);
                } catch (InterruptedException ex) {
                    ex.printStackTrace();
                }
            }
        });

        // 启动兔子和乌龟的线程
        rabbitThread.start();
        turtleThread.start();
    }

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

运行该程序，点击“Start”按钮即可开始比赛。程序模拟两个线程分别移动兔子和乌龟的位置，直到其中一个到达终点（即赛道的右侧）。
