模拟斗地主发牌并排序

题目

模拟斗地主发牌，并对其进行排序

分析

将牌盒定义为一个双链结合，为每个来建立一个索引;
然后为每个索引建立一个集合，洗牌和发牌都是使用索引；
将每个人各自的集合定义为 TreeSet 集合可以进行排序

程序代码

        int index = 0;

        }
        //看牌
        lookPoker("刘备", 刘备, pokerBox);

    }

    private static void lookPoker(String name, TreeSet<Integer> set, HashMap<Integer, String> pokerBox) {
        System.out.println(name);
        for (Integer key : set) {
