使用java对一副扑克牌建模

本文实例为大家分享了java对一副扑克牌建模的具体代码，供大家参考，具体内容如下

第一步：使用枚举法对一副扑克牌（52张牌，不包括大小王）进行建模：一副扑克牌共有四种花色分别是：黑桃，方块，梅花，红心；而每种花色的牌一共有13张；

import java.util.EnumMap;
import java.util.EnumSet;

public class EnumSetTest {
 //枚举类型Suit
 enum Suit{"HEART ","SPADE ","DIAMOND ","CLUB "};
 enum Rank{"A","2","3","4","5","6","7","8","9","10","J","Q","K"};
 }

第二步：创建2个枚举类型包含这两类实例。

每张扑克牌Card对象都会有这两个属性，创建一个带有这两个枚举类型属性的类Card

`package com.Cards.model;

package com.Cards.model;
 

public class Card
{
 
 private String color = null;
 private String num = null;
 
 private boolean visible = false;
 private boolean red = false;
 
 public Card(String color, String num)
 {
 this.color = color;
 this.num = num;
 
 // if the color is diamond or heart ,then red is true,else false
 if (color.equals(CardSetting.COLOR[CardSetting.INDEX_HEART])
 || color.equals(CardSetting.COLOR[CardSetting.INDEX_DIAMOND]))
 this.red = true;
 else
 this.red = false;
 }
 
 
 public boolean equals(Object obj)
 {
 Card anotherCard = (Card) obj;
 return this.color.equals((anotherCard.color))
 && this.num.equals(anotherCard.num);
 
 }
 
 public void setVisiable(boolean visible)
 {
 this.visible = visible;
 }
 
 public boolean isVisible()
 {
 return visible;
 }
 
 public boolean isRed()
 {
 return red;
 }
 

 public String toString()
 {
 if (this == null)
 return "EMPTY";
 else
 {
 if (this.isVisible())
 {
 return (color + " " + num + " ");
 }
 
 else
 return "███ ";
 }
 
 }
 
 public String getColor()
 {
 return color;
 }
 
 
 public int getNum()
 {
 char ch = num.charAt(0);
 switch (ch)
 {
 case 'A':
 return 1;
 case 'J':
 return 11;
 case 'Q':
 return 12;
 case 'K':
 return 13;
 default:
 return Integer.parseInt(num);
 }
 
 }
 
 
 public String getNumInString()
 {
 return num;
 }
}

第三步：初始化扑克牌排列顺序

public class CardHeap
{
 private Vector vector=null;
 
 public CardHeap()
 {
 this.initialize(); 
 }
 
 
 public void initialize()
 {
 vector=new Vector();
 Card tmp=null;
 for (int i = 0; i < 13; i++)//13 cards in Color Heart
 {
 tmp=new Card(CardSetting.COLOR[CardSetting.INDEX_HEART], CardSetting.NUM[i]);
 tmp.setVisiable(false);
 vector.add(tmp);
 }
 for (int i = 0; i < 13; i++)//13 cards in Color SPADE
 {
 tmp=new Card(CardSetting.COLOR[CardSetting.INDEX_SPADE], CardSetting.NUM[i]);
 tmp.setVisiable(false);
 vector.add(tmp);
 }
 for (int i = 0; i < 13; i++)//13 cards in Color DIAMOND
 {
 tmp=new Card(CardSetting.COLOR[CardSetting.INDEX_DIAMOND], CardSetting.NUM[i]);
 tmp.setVisiable(false);
 vector.add(tmp);
 }
 for (int i = 0; i < 13; i++)//13 cards in Color CLUB
 {
 tmp=new Card(CardSetting.COLOR[CardSetting.INDEX_CLUB], CardSetting.NUM[i]);
 tmp.setVisiable(false);
 vector.add(tmp);
 } 
 }
