本文例項為大家分享了java對一副撲克牌建模的具體程式碼，供大家參考，具體內容如下

第一步：使用列舉法對一副撲克牌（52張牌，不包括大小王）進行建模：一副撲克牌共有四種花色分別是：黑桃，方塊，梅花，紅心；而每種花色的牌一共有13張；

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

public class EnumSetTest {
  //列舉型別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：建立2個列舉型別包含這兩類例項。

每張撲克牌Card物件都會有這兩個屬性，建立一個帶有這兩個列舉型別屬性的類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

 * */
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,則認為是同一張牌
 * */
 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;
 }
 
 /* 以數字的方式,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：初始化撲克牌排列順序

public class CardHeap
{
 private Vector<Card> vector=null;
 
 public CardHeap()
 {
 this.initialize(); 
 }
 
 /*初始化13*4=52張牌*/
 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);
 } 
 }
