编写一段Java九宫格拼图游戏gui的代码

好的，以下是一个简单的Java九宫格拼图游戏GUI的代码，使用Java Swing库实现：

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

public class PuzzleGUI extends JFrame {
    private JPanel puzzlePanel;
    private JButton newGameButton;
    private JButton quitButton;

    public PuzzleGUI() {
        super("Puzzle Game");

        // Create the panel to display the puzzle
        puzzlePanel = new JPanel(new GridLayout(3, 3));
        puzzlePanel.setPreferredSize(new Dimension(300, 300));
        add(puzzlePanel, BorderLayout.CENTER);

        // Create the new game button
        newGameButton = new JButton("New Game");
        newGameButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                // Start a new game
                startNewGame();
            }
        });

        // Create the quit button
        quitButton = new JButton("Quit");
        quitButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                // Exit the game
                System.exit(0);
            }
        });

        // Add the buttons to the frame
        JPanel buttonPanel = new JPanel(new FlowLayout());
        buttonPanel.add(newGameButton);
        buttonPanel.add(quitButton);
        add(buttonPanel, BorderLayout.SOUTH);

        // Set the frame properties
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        pack();
        setLocationRelativeTo(null);
        setVisible(true);
    }

    private void startNewGame() {
        // TODO: Implement the new game logic
        // Add the puzzle pieces to the panel
        for (int i = 1; i <= 9; i++) {
            JButton button = new JButton("" + i);
            button.setPreferredSize(new Dimension(100, 100));
            puzzlePanel.add(button);
        }
        puzzlePanel.revalidate();
        puzzlePanel.repaint();
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                new PuzzleGUI();
            }
        });
    }
}

这段代码创建了一个包含一个面板和两个按钮的窗口。面板用于显示九宫格拼图，按钮用于开始新游戏和退出游戏。在开始新游戏按钮的监听器中，我们向面板添加了九个按钮，每个按钮代表拼图中的一个块。当用户点击这些按钮时，您需要实现拖动和交换拼图块的功能。
