感想：
一开始不了解或者说是对JAVA的特性不熟悉，不知道类与类之间的联系，对JAVA的封装，继承，多态不熟悉和没有更好的理解，在以后的学习过程中要掌握并熟悉JAVA的开发习惯，
在写代码过程中还有众多东西没有掌握，靠着老师和同学的帮助完成这次学习，初步了解了JAVA面向对象开发的基本要领。写这个博客以便于自己今后学习，也算是一段美好的回忆吧！
上面是一个类图 表示着写这个程序的只要思路。
Card类:他的下级是cardview上级是player,有着一定的关系
package com.cqvie;
public class Card
{
public int rank,suit;
public int cardIdx;
public CardView cardView;
public Player owner;
public boolean selected=false;
public static String suits[]
=new String[]{"","♠","♥","♣","♦"};
public static String ranks[]
=new String[]{"J","Q","K","A","2","小王","大王"};
public Card(int rank,int suit)
{
this.rank=rank; this.suit=suit;
this.cardView=new CardView(this); //在产生Card对象时，要同步产生CardView对象
}
public String toString()
{
if(rank<=10) //10点或以下
return suits[suit]+rank;
else //10点以上
return suits[suit]+ ranks[rank-11];
}
}

Test类：
package com.cqvie;
public class Test {
public static void main(String[] args) {
GameManager gm=new GameManager();
gm.startGame();
gm.show();
}
}
