The examples in this article share the specific code for implementing Simple Landlord in Java for your reference. The specific content is as follows

* 项目编码格式：
* 1.GBK:只支持简体中文
* 2.GB2312:支持简体和繁体
* 3.UTF-8:国际通用的编码格式
*
* 模拟实现斗地主发牌的过程实现步骤
* 1.准备一副扑克牌
* a.定义一个Map集合用来存放54张扑克 map的key(下标)对应的是map的值(扑克)
* b.定义一个list集合 用来保存map集合的key(map集合的key就对应map集合的值)
* c.定义一个String类型的数组 用来构建牌的花色[♥,♠,♦,♣]
* d.定义一个String的数组 用来保存扑克具体的值[3,4,5,6,7,8,9,10,J,Q,K,A,2]
* e.把大王和小王添加到Map集合中
* 2.洗牌
* 通过集合的一个操作类Collections提供的一个相关方法实现洗牌的操作
* 3.发牌的过程
* a.定义三个玩家和一个接收底牌的集合容器
* b.遍历ArrayList集合中 如何实现每个玩家轮流拿牌
* 【J,Q,9,10,2,A........Q】
* 【0,1,2,3,4,5.........53】
* 发牌思路分析：
* 如果当前的下标大于等于51 剩下的牌留作底牌
* 可以使用下标对3求余数 0%3 = 0 把J给玩家1 1%3 = 1 把Q给玩家2 2%3 = 2 把9给玩家3 3%3 =0 把10给玩家1 4%3 = 1
* 4.排序
* 5.看牌
* 实现每个玩家的牌输出展现
*

/*
* 思路总结：
* 根据下标排序，所以用map，key就是下标，对应值就是扑克(花色+数)
* 洗牌的shuffle,排序的sort方法只能对list管用
* 所以用list集合盛放key,对key洗牌，然后对key排序
* 用key去map里去对应的值
