本文實例為大家分享了java對一副撲克牌建模的具體代碼，供大家參考，具體內容如下

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; /** * @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,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); } }
