如何在Java中通过按一下按钮来显示新的随机图像？

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

public class RandomImageDisplay extends JFrame {
    private JLabel imageLabel;
    private JButton randomButton;
    private String[] imageFiles = {"image1.jpg", "image2.jpg", "image3.jpg"}; // 随机图像文件列表

    public RandomImageDisplay() {
        setTitle("Random Image Display");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 400);

        // 创建图像标签和按钮
        imageLabel = new JLabel();
        randomButton = new JButton("Random Image");

        // 添加按钮点击事件监听器
        randomButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // 随机选择一个图像文件
                Random random = new Random();
                int index = random.nextInt(imageFiles.length);
                String selectedImage = imageFiles[index];

                // 加载并显示图像
                ImageIcon imageIcon = new ImageIcon(selectedImage);
                imageLabel.setIcon(imageIcon);
            }
        });

        // 设置布局并添加组件
        setLayout(new BorderLayout());
        add(imageLabel, BorderLayout.CENTER);
        add(randomButton, BorderLayout.SOUTH);
    }

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