JAVA语言课程设计——扫雷小游戏代码

以下是一个简单的扫雷小游戏的 JAVA 代码，实现了基本的游戏功能：

代码中定义了游戏的行数，列数和雷数，以及用来表示板块状态的字符常量。在 `Minesweeper` 类中，通过二维数组 `board` 和 `bombPositions` 来表示游戏面板和雷的位置。通过 `initBoard` 和 `initBombs` 方法初始化游戏面板和雷的位置。

在 `countAdjacentBombs` 方法中，根据当前位置的周围八个位置计算雷的个数。

在 `playMove` 方法中，根据当前位置是否有雷计算该位置的状态，并根据周围是否有雷递归更新周围的位置状态。

在 `playGame` 方法中，通过 `Scanner` 类读取玩家的输入，并根据输入更新游戏状态，直到游戏结束。

在 `checkWin` 方法中，检查游戏是否胜利。

在 `printBoard` 方法中，输出游戏面板。

在 `main` 方法中，创建 `Minesweeper` 对象并调用 `playGame` 方法开始游戏。
