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;

/**
 * @author Rock Lee
 * @version 2012-10-21 16:51:49
 * @see CardSetting.java
 * @proposal Build A Class Contain All the info for ONE Card in the poker
 * @fix 2012-12-12 13:01:04
 * */
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;
 }

 /*
 * 若花色,牌面大小相同,则认为是同一张牌
 * */
 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;
 }

 /* 以数字的方式,返回牌面的大小 */
 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);
 }

 }

 /* 以String的方式,返回牌面的大小 */
 public String getNumInString()
 {
 return num;
 }
}

第三步：初始化扑克牌排列顺序

public class CardHeap
{
 private Vector<Card> vector=null;

 public CardHeap()
 {
 this.initialize();
 }

 /*初始化13*4=52张牌*/
 public void initialize()
 {
 vector=new Vector<Card>();
 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);
 }
 }
