java设计界面并实现扫雷游戏的代码

好的，下面是Java设计界面并实现扫雷游戏的代码示例：

        }
    }

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

这个代码示例实现了一个10x10的扫雷游戏，其中有10个地雷。玩家可以点击每个方格，如果方格中没有地雷，则会显示周围的地雷数量。如果方格中有地雷，则游戏结束，并弹出“Game over”对话框。如果玩家成功揭开了所有没有地雷的方格，则游戏胜利，并弹出“You win”对话框。玩家可以点击“Restart”按钮重新开始游戏。
