java----实现简单的21点纸牌游戏
- 游戏设计思路：
电脑和玩家的⽐拼：谁⼿中扑克牌的“点数和”⾸先达到21点为获胜⽅，或者在双⽅都叫停的情况下谁的“点数和”越接近21点且不⼤于21点为获胜⽅，凡是⼤于21点或者“点数和：⼩于对⽅的”点数和“的⼀⽅为输。
⼤⼩王的点数为0；
J,Q,K的点数为10；
其余的点数都与⾃⼰所表⽰的数字⼀样；
设计⽅法：
1.定义⼀个类：设置每⼀张扑克牌所具有的属性，将其点数，花⾊等等设置好；
2.定义⼀个类：设置⼀副扑克牌所具有的属性，⽐如洗牌，加载图⽚等；
3.定义⼀个游戏界⾯类：将整个游戏界⾯显⽰出来，其中包括⼀些游戏逻辑函数，计算得分，绘图等等
操作；
4.定义⼀个游戏开始的⼊⼝类，加载游戏界⾯和⼀些基本的界⾯属性按键，设计游戏整体界⾯的格局；
说多了都是泪（类），直接上代码整！
Cards类：⼀张扑克牌的属性设置，⽐如点数，花⾊等；

简单的java游戏代码public void drawCards(Graphics g, JPanel i)//在⾯板i上⾯画扑克牌对象

public void drawBackgroundCards(Graphics g, JPanel i)

public void print()
{

Poker类：⼀副扑克牌的⼀些基本属性，⽐如牌的图⽚，牌的获取，洗牌等操作；
package cords_21_game;

//import java.util.Random;

for(int j = 0; j < value.length; j++)//⾯值
{
cardsImage[i*value.length + j] = DefaultToolkit().getImage("F:/Image/21_cards\\"+(i+1)+"-"+(j+1)+".png"); }

}
public Poker()
{

{
cards[i*13+j] = new Cards(color[i], value[j], cardsImage[i*13+j]);
}
}

}
public void WashCards()

for(int i = 0; i < cards.length; i++)
{

Cards temp = cards[i];
cards[i] = cards[p];
cards[p] = temp;
}
}
public Cards[] getCard()//获取⼀副扑克对象
{

}
public Cards getOneCard(int n)//获取⼀张扑克牌对象
{

}
public void show()//显⽰所有的牌对象color 和 value信息
