项目简介
经典小游戏扫雷。游戏目标是在最短的时间内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。左键打开方块，右键标记地雷。点击中间状态重置游戏，滚轮重新选择难度。
项目关键技术
java变量、java数据类型、判断语句、循环结构、数组、Java集合、简单窗口创建、图形图片绘制、双缓存技术、鼠标事件、awt抽象窗口工具包、部分复杂算法、GUI界面、面向对象程序设计等。
开发环境：jdk17
开发工具：IDEA
项目需求分析：
1.鼠标左键点击可翻开方块。
2.鼠标右键点击可标记地雷（插旗）。
3.点击到空白区域可使相连所有空白区域和数字区域被翻开。
4.鼠标滚轮键可返回难度选择页面。
5.标记所有的地雷即胜利，翻到地雷则失败。
