感想：
第一次写博客，感觉编辑器挺复杂厉害的，感觉自己的内容挺简单的。有什么问题请多多指教！
思路：
1、创建一个扑克牌的实体类poker，设置了四个参数：花色、数字、牌值（判断大小）、是否地主牌，实现getset方法和构造方法；
2、创建一个玩家的实体类player，设置了四个参数： 初始牌集合，排序后牌集合，牌值集合，是否地主，实现getset方法和构造方法；
3、洗牌：循环嵌套花色数组跟数字数组生成52个poker，手动加入大小王poker，放进map(int,poker)里面，利用collections.shuffle随机排序map的key，再根据key生成排序后的poker集合
4、发牌：生成3个玩家对象，拿到洗牌后的集合，前51张牌为玩家牌，后3张为地主牌，在51张牌中随机一张为地主牌，遍历玩家牌分配个每一个player，同时根据玩家牌的牌值生成集合grades存进player对象中，将grades转为int数组并进行升序排序，根据grade取得新poker集合分配给玩家。
