用java编写一个完整的拼图游戏界面

好的，以下是一个用Java Swing编写的拼图游戏界面的示例代码，仅供参考。

import java.awt.event.ActionListener;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

            }
        }

        timer = new Timer(1000, new ActionListener() {
            @Override

                    JOptionPane.showMessageDialog(this, "恭喜您，拼图成功！", "游戏结束", JOptionPane.PLAIN_MESSAGE);
                }

        }
    }

    private boolean isAdjacent(int index1, int index2) {
        int row1 = index1 / COLS;

        }

            return true;

        return false;
    }

    private boolean isWin() {
        for (int i = 0; i < ROWS * COLS - 1; i++) {
            JButton button = puzzleButtonList.get(i);
            if (button == null || !button.getText().equals(String.valueOf(i + 1))) {
                return false;
            }
        }
        return true;
    }

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

这个示例代码实现了一个3x3的拼图游戏界面，包括拼图块的随机排列、计时、计步等功能。如果你想要实现更大的拼图游戏，可以根据这个示例代码进行扩展。
