大家對于撲克牌都不陌生，畢竟是作為我們?nèi)粘Ｉ钪幸豁椇唵斡腥?，又能促進親朋好友之間關系的游戲。本篇文章將為大家講述如何使用 Java 代碼自己敲一個簡單而有趣的撲克牌小游戲，從而促進 Java 語言的理解。
功能描述
1、創(chuàng)建撲克牌。包括四種花色（黑桃，紅心，梅花，方塊），十三種點數(shù)（2-10，J，Q，K），不考慮大小王。
2、創(chuàng)建兩個玩家。包括玩家id、姓名、手牌等集合，手牌為撲克牌的集合。
3、洗牌。將創(chuàng)建好的撲克牌打亂。
4、發(fā)牌。將洗牌之后的撲克牌集合，從第一張開始，發(fā)給兩個玩家，安裝一人 一張的方式，每人發(fā)兩張。
5、游戲。比較兩名玩家手中的撲克牌。規(guī)則為：去兩名玩家手上點數(shù)最大的牌進行比較，點數(shù)大的贏，若點數(shù)一樣大，就按照色花進行比較。
難點分析：
1、洗牌，如何將撲克牌進行打亂。（主要知識點Random，list.contains()）
2、撲克牌如何進行大小比較。（主要知識點collections.sort() , comparable）
