扫雷代码java_JAVA实现扫雷游戏

好的，以下是一个简单的 Java 实现扫雷游戏的代码示例：

    }

            int row = scanner.nextInt() - 1;
            int col = scanner.nextInt() - 1;
            if (row == -2 && col == -2) {

}

这个简单的实现中，我们使用了一个 10x10 的二维字符数组来表示游戏板。我们还有一个相同大小的二维布尔数组，用于跟踪哪些方格上有地雷。在每个游戏回合中，玩家输入要揭开的方格的行和列号，程序将检查这个位置是否有地雷。如果是，游戏结束，否则程序将显示该位置周围的地雷数量，并揭开与该位置相邻的所有空白方格。玩家还可以标记他们认为有地雷的方格。如果玩家揭开了所有不是地雷的方格，游戏结束，玩家获胜。
