Java斗地主小游戏有序版

题目

斗地主综合案例:有序版
1.准备牌:大王小王
52张牌:循环嵌套遍历两个集合,组装52张牌
可以使用Map集合储存牌的索引+组装好的牌。创建一个List集合存储牌的索引
2.洗牌:使用Collections中的方法shuffle(List)
3.发牌:一人一张轮流发牌,每人17张,集合索引%3,剩余3张给底牌.(注意:要先判断底牌 i > 50,即在第51张牌开始给底牌发)
4.排序:使用Collections中的方法sort(List)
5.看牌:可以用查表的方法
遍历一个集合,获取到另外一个集合的key,通过key查找到value
遍历玩家和底牌的List集合,获取到Map集合的key,通过key找到value值
***【注意】***:使用了JDK9及以上版本才可以使用的List.of()。

List<String> colors = List.of("♠","♥","♣","♦");
List<String> numbers = List.of("2","A","K","Q","J","10","9","8","7","6","5","4","3");

如果是JDK9以下的版本,可以建立两个数组:

String[] colors = {"♠","♥","♣","♦"};
String[] numbers = {"2","A","K","Q","J","10","9","8","7","6","5","4","3")};
