程序分析
使用Java编写的扫雷游戏界面程序，主要内容总结如下：
Frame类继承自JFrame，构建了扫雷游戏的界面。- 包含文本框
text、标签nowBomb和setBomb、按钮start、面板MenuPamel和bombPanel等组件。 - 通过
jbInit方法进行初始化设置，包括布局、组件添加和事件监听等。
- 包含文本框
- 游戏逻辑相关方法：
start_actionPerformed：处理开始按钮的动作，根据设置的地雷数进行相应操作。startBomb：开始布雷，设置地雷位置并计算周围雷数。CountRoundBomb：计算方块周围的雷数。isWin：判断是否挖完了所有的雷。isNull：当选中的位置为空时，翻开周围的地图。turn：翻开方块。actionPerformed：处理左键点击事件。mouseClicked：处理右键点击事件。
- 内部类：
Frame1_start_actionAdapter：处理开始按钮的动作事件。Bomb：表示游戏中的方块按钮，包含相关属性和方法。Bomb_actionAdapter：处理方块按钮的动作事件。Bomb_mouseAdapter：处理方块按钮的鼠标点击事件。
最后，在main方法中创建Frame对象并使其可见，启动游戏界面。
