這篇文章主要為大家展示了如何使用java對一副撲克牌建模，內容簡而易懂，希望大家可以學習一下，學習完之后肯定會有收獲的，下面讓小編帶大家一起來看看吧。
第一步：使用枚舉法對一副撲克牌（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 {
//枚舉類型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：創建2個枚舉類型包含這兩類實例。
每張撲克牌Card對象都會有這兩個屬性，創建一個帶有這兩個枚舉類型屬性的類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;
}
/*
* 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);
}
