/**
 * 目标：斗地主游戏的案例开发。
 * <p>
 * 业务需求分析:
 * 斗地主的做牌，洗牌，发牌,排序（拓展知识）, 看牌
 * 业务:总共有54张牌。
 * 点数: "3","4","5","6","7","8","9","10","J","Q","K","A","2"
 * 花色: "♠", "♥", "♣", "♦"
 * 大小王: "👲" , ""
 * 点数分别要组合4种花色，大小王各一张。
 * 斗地主：发出51张牌，剩下3张作为底牌。
 * <p>
 * 功能：
 * 1.做牌。
 * 2.洗牌
 * 3.定义3个玩家。
 * 4.发牌。
 * 5.排序（拓展，了解）
 * 6.看牌。
 * <p>
 * 用面向对象设计案例：
 * a.定义一个牌类，代表牌对象。 一个牌对象代表一张牌。
 * b.定义一个集合存储54张牌，集合只需要一个(因为牌只需要一副)
