?项目结构
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!
