我们的学校项目包括从Internet上获取已经完成的程序（例如游戏），并为其添加一些新功能。我决定从JGameGrid购买纸牌游戏mau-mau，我想添加以下功能：
当某人在中途添加带有数字“ 7”的卡时，下一位玩家必须将2张卡作为罚金。当他在中间放下第二张数字为“ 7”的牌时，他可以避免这种惩罚，因此，随后的玩家必须采取4张牌作为惩罚。直到有人无法放下卡片7为止。此人必须承担全部罚款。
当某人在中间添加数字为“ 8”的卡时，下一位玩家必须暂停一轮。当他放下第二张数字为“ 8”的卡片时，他可以避免这种惩罚。因此，他不必暂停，但随后的玩家必须暂停。直到有人无法放下卡片8为止。此人必须暂停。
当有人在中间添加带有数字“ 9”的卡时，方向将会改变。如果有人放下卡片9，每个人都可以更改方向。
两年以来我一直在学习程序设计，所以Java对我来说相对较新，并且在Stack Overflow上还很新。因此我需要提示如何添加函数。
代码如下：
