二、项目介绍
项目背景
扫雷是一款大众类的益智小游戏。根据点击格子出现的数字找出所有非雷格子，同时避免踩雷，踩到一个雷即全盘皆输。这款游戏有着很长的历史，从扫雷被开发出来到现在进行了无数次的优化，这款游戏通过简单的玩法，加上一个好看的游戏界面，每一处的细节都体现了扫雷的魅力。
功能分析
完成 难度选择，雷随机生成，数字生成，左右键翻开 等功能实现
游戏四种状态： 难度选择、游戏状态、游戏胜利、游戏失败
游戏难度： 初级、中级、高级（不同难度对应不同的雷区大小和雷数量）
游戏核心： 二维数组 的相关操作
其他： 窗口绘制、界面规划、操作计数、重新开始。
三、代码展示
图形界面设计（gui包）
主类：AppWindows类
AppWindow类负责创建游戏的主窗口，该类含有main方法,程序从该类开始执行。

六、设计总结
本次项目设计是通过 Java语言编制一个扫雷游戏，Java语言是当今较为流行的网络编程语言，它具有面向对象、跨平台、分布应用等特点。这次设计，还有利于加深对 Java课程的进一步了解，也可以巩固所学 Java语言基本知识，增进 Java语言编辑基本功，拓宽常用类库的应用。采用面向对象思想的程序，锻炼了面向对象的设计能力，使编程者通过该教学环节与手段，把所学课程及相关知识加以融会贯通，全面掌握 Java语言的编程思想及面向对象程序设计的方法。
