/**
* 模仿斗地主洗牌,随机发牌
* 使用TreeMap、ArrayList、TreeSet
* 思想:
* 使用TreeMap存54张牌,每张牌作为值,key为每张牌整数编号1-54,取出键进行乱序牌,
* 之后发给三个人存在TreeSet自动会排序,然后偶循环通过键获得每张牌,斗地主不考虑花色

// 定义点数
String[] point = { "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q",
"K", "A", "2" };
// 定义花色
// String[] fC = { "红心", "方块", "黑桃", "梅花" };
String[] fC = { "♥", "♦", "♠", "♣" };
// 定义扑克集合

// 生成扑克

// System.out.println(mapPoker + "\n");

//获取所有键
Set<Integer> keys = mapPoker.keySet();
//把键个封装到ArrayList集合,便于使用Collections集合工具类洗牌
ArrayList<Integer> poker = new ArrayList<>();
for (Integer integer : keys) {
poker.add(integer);
}
// System.out.println("洗牌前key:" + poker);

// 洗牌
//使用集合工具类洗牌
Collections.shuffle(poker);

// 派牌、码牌(TreeSet),定义了三个人man1、man2、man3,底牌 diPoker

//三方牌装到ArrayList便于每个man遍历打印
