java集合框架(斗地主洗牌发牌)

package dou_di_zhu;

import java.util.ArrayList;
import java.util.Collection;
import java.util.Collections;
import java.util.HashMap;
import java.util.TreeSet;

/**
 * 思路:
 *         A:创建一个HashMap集合
 *         B:创建一个ArrayList集合
 *         C:创建花色数组和点数数组
 *         D:从0开始往HashMap里面存储编号,并存储对应的牌
 *             同时往ArrayList里面存储编号即可
 *         E:洗牌(洗的是编号)
 *         F:发牌(发的也是编号,为了保证编号是排序的,就创建TreeSet集合接收)
 *         G:看牌(遍历TreeSet集合,获取编号,到HashMap中找对应的牌)
