【游戏】java入门 -- 使用LinkedLIst完成一个【洗牌】游戏

import java.util.LinkedList;

import java.util.Random;

/*

* Collection

* ------| List 实现了List集合接口的类，特点是有序不可重复

*-----------| ArrayList 内部维护了一个对象数据，增删慢，但是查询块

*-----------| LinedList 内部是一个链表的数据结构，增删改块，查询慢

*-----------| Vector

* ------| Set 实现Set集合接口的类，特点是无序不可重复
