简易扑克牌游戏的简易实现-原创手记-慕课网

今天学完了Java入门第三季的最后一课，完成了课后作业，实现了简易扑克游戏。游戏很简单，代码实现也不难，但做了这个很能理解Java面向对象的作用。就这个游戏而言，我主要是分为三个class：Poker，Player，Game。

扑克牌类，包含元素是扑克牌的点数和花色，并且定义扑克牌之间比较大小的规则。
玩家类复杂点，除了玩家的ID和名字，还有所拥有的手牌，在后面发现游戏用到的最大手牌，也设在玩家类里，这样能更好处理对应关系。
主程序main在Game里面，把游戏的整个过程实现出来，分步用成员函数实现：新建整副扑克牌，产生游戏玩家，洗牌，发牌，开始游戏。

程序运行如下图：

剩下的代码来展示，注释比较少，但输出的提示应该够看了。
