本程序共封装了六个类，分别是主类GameWin类，绘制底层地图和绘制顶层地图的类MapBottom类和MapTop类，绘制底层数字的类BottomNum类，以及初始化地雷的BottomRay类和工具GameUtil类，用于存静态参数和方法，最后用于难度选择的方法封装在GameSelect类中。
程序界面布局
不同的难度雷区格子数不同！
总结
游戏的设计类似windows扫雷，用户在图形化用户界面内利用鼠标监听事件标记雷区，左上角表示剩余雷的数量，右上角动态显示使用的时间。用户可选择中间组件按钮重新游戏。
为了解决程序窗口闪动的问题，本程序采用了双缓冲技术。 在使用Java编写扫雷小游戏时遇到了很多问题，在解决问题时，确实对java的面向对象编程有了更加深入的理解。虽然GUI现在并没有很大的市场，甚至好多初学者已经放弃了学习GUI，但是利用GUI编程的过程对于培养编程兴趣，深入理解Java编程有很大的作用。
本程序是初学者练习的好项目，欢迎大家指正！
