用java创建一副扑克牌

用java怎么创建一副扑克牌
一张扑克牌有两个属性,一个是花色(suit),一个是点数(rank),下面写一个简单的类Card

package com.syz.card;

import java.io.Serializable;

public class Card implements Serializable{

    private static final long serialVersionUID = -4279016186402068401L;

    private int suit;

    private int rank;

    public static final int SPADE = 0;

    public static final int HEART = 1;

    public static final int CLUB = 2;

    public static final int DIAMOND = 3;

    public static final int BLACK = 4;

    public static final int RED = 5;

    private static final String[] suits = new String[] { "黑桃", "红桃", "梅花", "方块",
            "小", "大" };

    public static final int ACE = 1000;

    public static final int TWO = 1001;

    public static final int THREE = 1002;

    public static final int FOUR = 1003;

    public static final int FIVE = 1004;

    public static final int SIX = 1005;

    public static final int SEVEN = 1006;

    public static final int EIGHT = 1007;

    public static final int NINE = 1008;

    public static final int TEN = 1009;

    public static final int JACK = 1010;

    public static final int QUEEN = 1011;

    public static final int KING = 1012;

    public static final int JOKER = 1013;

    private static final String[] ranks = new String[] { "A", "2", "3", "4",
            "5", "6", "7", "8", "9", "10", "J", "Q", "K", "王" };

    public Card(int suit, int rank) {
        if (suit > -1 && suit < 6) {
            if (suit < 4) {
                if (rank < 1000 || rank > 1012) {
                    throw new IllegalArgumentException("花色或点数参数错误!");
                }
            }
            else {
                if (rank != 1013) {
                    throw new IllegalArgumentException("花色或点数参数错误!");
                }
            }
        }
        else {
            throw new IllegalArgumentException("花色参数错误!");
        }
        this.suit = suit;
        this.rank = rank;
    }

    public int getSuit() {
        return suit;
    }

    public int getRank() {
        return rank;
    }

    @Override
    public String toString() {
        return suits[suit] + ranks[rank - 1000];
    }

}

写完之后,要new一张扑克牌,需要两个参数,suit和rank,而且suit和rank是有关系的黑红梅方可以对应A2345678910JQK,然后黑色小王,红色大王。这个在构造器里做了校验,如果不符合,则抛出参数错误异常。
下面是测试类
CardClient

package com.syz.card;

import java.util.ArrayList;
import java.util.List;

public class CardClient {
    public static void main(String[] args) {
        test2();

    }

    private static void test1() {
        Card c = new Card(Card.BLACK, Card.JOKER);
        System.out.println(c);
    }

    private static void test2() {
        int[] suits = new int[] { Card.SPADE, Card.HEART, Card.CLUB,
                Card.DIAMOND };
        int[] ranks = new int[] { Card.ACE, Card.TWO, Card.THREE, Card.FOUR,
                Card.FIVE, Card.SIX, Card.SEVEN, Card.EIGHT, Card.NINE,
                Card.TEN, Card.JACK, Card.QUEEN, Card.KING };
        List cards = new ArrayList();
        for (int i = 0; i < suits.length; i++) {
            for (int j = 0; j < ranks.length; j++) {
                cards.add(new Card(suits[i], ranks[j]));
            }
        }
        cards.add(new Card(Card.BLACK, Card.JOKER));
        cards.add(new Card(Card.RED, Card.JOKER));
        System.out.println(cards);
    }
}

测试结果:
[黑桃A, 黑桃2, 黑桃3, 黑桃4, 黑桃5, 黑桃6, 黑桃7, 黑桃8, 黑桃9, 黑桃10, 黑桃J, 黑桃Q, 黑桃K, 红桃A, 红桃2, 红桃3, 红桃4, 红桃5, 红桃6, 红桃7, 红桃8, 红桃9, 红桃10, 红桃J, 红桃Q, 红桃K, 梅花A, 梅花2, 梅花3, 梅花4, 梅花5, 梅花6, 梅花7, 梅花8, 梅花9, 梅花10, 梅花J, 梅花Q, 梅花K, 方块A, 方块2, 方块3, 方块4, 方块5, 方块6, 方块7, 方块8, 方块9, 方块10, 方块J, 方块Q, 方块K, 小王, 大王]这样一副扑克就创建成功了。扑克原来有52张,没有大小王,后来才加上了大小王。现在有些扑克会带一张白板牌里面是一些广告什么的,如果把这张牌加入的话,就得改改这个Card类了。下面我们来看看第二种方式创建一副扑克牌,不过这儿的类有些多,好处就是可以扩展。看代码:

1.Suit

package com.syz.pattern.bridge;

public abstract class Suit {
    private Face face;

    public Suit(Face face) {
        this.face = face;
    }

    public void show() {
        face.show(this);
    }

    protected abstract String getName();
}

2.Face

package com.syz.pattern.bridge;

public abstract class Face {

    protected abstract String getName();

    public void show(Suit suit) {
        System.out.println(suit.getName() + this.getName());
    }
}



以上两个抽象类,相互引用。是花色和点数的父类。
Suit的几个子类:

package com.syz.pattern.bridge;

public class Spade extends Suit {

    public Spade(Face face) {
        super(face);
    }

    @Override
    public String getName() {
        return "黑桃";
    }
}

package com.syz.pattern.bridge;

public class Heart extends Suit {

    public Heart(Face face) {
        super(face);
    }

    @Override
    protected String getName() {
        return "红桃";
    }

}

package com.syz.pattern.bridge;

public class Club extends Suit {

    public Club(Face face) {
        super(face);
    }

    @Override
    protected String getName() {
        return "梅花";
    }

}

package com.syz.pattern.bridge;

public class Diamond extends Suit {

    public Diamond(Face face) {
        super(face);
    }

    @Override
    protected String getName() {
        return "方块";
    }

}

package com.syz.pattern.bridge;

public class Black extends Suit {

    public Black(Face face) {
        super(face);
    }

    @Override
    protected String getName() {
        return "小";
    }

}

package com.syz.pattern.bridge;

public class Red extends Suit {

    public Red(Face face) {
        super(face);
    }

    @Override

        return "大";
    }

}

Face的几个子类

    protected String getName() {
        return "A";
    }

}

package com.syz.pattern.bridge;

public class Two extends Face {

    @Override
    protected String getName() {
        return "2";
    }

}

    @Override
    protected String getName() {
        return "3";
    }

}

package com.syz.pattern.bridge;

public class Four extends Face {

    @Override
    protected String getName() {
        return "4";
    }

}

package com.syz.pattern.bridge;

public class Five extends Face {

    @Override
    protected String getName() {
        return "5";
    }

}

package com.syz.pattern.bridge;

public class Six extends Face {

    @Override
    protected String getName() {
        return "6";
    }

}

package com.syz.pattern.bridge;

public class Seven extends Face {

    @Override
    protected String getName() {
        return "7";
    }

}

package com.syz.pattern.bridge;

public class Eight extends Face {

    @Override
    protected String getName() {
        return "8";
    }

}

package com.syz.pattern.bridge;

public class Nine extends Face {

    @Override
    protected String getName() {
        return "9";
    }

}

package com.syz.pattern.bridge;

public class Ten extends Face {

    @Override
    protected String getName() {
        return "10";
    }

}

package com.syz.pattern.bridge;

public class Jack extends Face {

    @Override
    protected String getName() {
        return "J";
    }

}

package com.syz.pattern.bridge;

public class Queen extends Face {

    @Override
    protected String getName() {
        return "Q";
    }

}

package com.syz.pattern.bridge;

public class King extends Face {

    @Override
    protected String getName() {
        return "K";
    }

}

package com.syz.pattern.bridge;

public class Joker extends Face {

    @Override
    protected String getName() {
        return "王";
    }

}
