第二篇：扫雷扫雷
扫雷不能不说一款非常经典的游戏，无聊时候可以打发时间，虽然玩了很久，但还不知道它是怎么写的，所以自己就尝试动手做了个。
众所周知，java的swing采用mvc模式，即模型-视图-控制器，所以如果真的了解了这个模式，较c++,用java做个游戏还是比较容易的。下面是我写的扫雷的代码

代码主要包含三个类，MineSweep,MinePanel和Mine类。
MineSweep包含main函数，为程序的入口，此外还负责初始化一个游戏界面的框架。
MinePanel为整个程序的核心，负责响应鼠标事件，游戏逻辑的处理，视图的刷新。其包含的openNear和generateNum方法为逻辑处理的核心。openNear方法主要功能是当被打开的一个方格不包含任何内容时（即它周围不包含雷），则它打开周围不为地雷的方格。这个方法主要用到广度优先搜索算法，用一个队列实现。而generateNum方法目的是初始化地图，即它是生成每个雷周围的数字。 Mine表示每个方格，里面包含每个方格的属性，flag是判断该方格是否被右键标上旗子，open判断该格子是否已经被打开，isMine判断是否是地雷，此外还有其他属性。
整个程序的逻辑流程如下
最后，附上程序包。解压后直接双击扫雷.jar即可运行。
