Java 扫雷游戏

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：

1. 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。
2. 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。
3. 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。
