前言
windows自带的游戏《扫雷》是陪伴了无数人的经典游戏，本程序参考《扫雷》的规则进行了简化，用java语言实现，采用了swing技术进行了界面化处理，设计思路用了面向对象思想。
主要需求
1、要有难度等级，初级，中级，高级
2、由玩家逐个翻开方块，以找出所有地雷为最终游戏目标。如果玩家翻开的方块有地雷，则游戏结束
3、游戏主区域由很多个方格组成。使用鼠标左键随机点击一个方格，方格即被打开并显示出方格中的数字；方格中数字则表示其周围的8个方格隐藏了几颗雷。
4、用户右键可标记雷的位置
5、雷都被标记出来则胜利
主要设计
1、格子格数固定为10*10格
2、难度等级，初级：12，中级：24，高级：36
3、点击格子时，产生没有引爆的地图效果；
4、点击格子时，此格子是雷，则显示所有雷的位置，并递归清空非雷格子，结束游戏
5、实现检查所有的雷是否都被标记出来了，如果是，则胜利算法。
6、实现计时器算法，用来计时显示游戏开始多少秒
7、实现难度等级，雷数的显示
8、实现鼠标左键的实现逻辑
9、实现鼠标右键的标记逻辑

}总结
通过此次的《扫雷》游戏实现，让我对swing的相关知识有了进一步的了解，对java这门语言也有了比以前更深刻的认识。
java的一些基本语法，比如数据类型、运算符、程序流程控制和数组等，理解更加透彻。java最核心的核心就是面向对象思想，对于这一个概念，终于悟到了一些。
