通过java集合

通过java集合

在这里值模拟得到斗地主的洗牌，发牌，看牌的功能

先来个Card里来定义一张牌

public class Card {// 每一张牌都是由点数和花色组成的(除大小王外)private String color;private String point;public Card(String color, String point) {super();lor = color;this.point = point;}@Overridepublic String toString() {return color + point;}public String getColor() {return color;}public void setColor(String color) {lor = color;}public String getPoint() {return point;}public void setPoint(String point) {this.point = point;}
}

然后在来一个比较器，便于每个人在看牌的时候牌都是排好序的

import java.util.Comparator;public class ListCompare implements Comparator<Card> {@Overridepublic int compare(Card o1, Card o2) {// TODO Auto-generated method stub//先比较点数，点数如果比不出来，则比较花色Point().Point())) {return getColors(o1)-getColors(o2);	}else {return getPoint(o1)-getPoint(o2);			}}//穿进去一张牌，取他点数对应的一个数字，方便排序public static int getPoint(Card o1) {int count=0;switch (o1.getPoint()) {case "J":count =11;break;case "Q":count =12;break;case "K":count =13;break;case "A":count =14;break;case "2":count =15;break;case "S":count =30;break;case "M":count =40;break;default:count=Integer.Point());}return count;}public int getColors(Card o1) {int count=0;switch (o1.getColor()) {case "♣":count=4;break;case "♥":count=3;break;case "♠":count=2;break;default:count=1;break;}return count;}}
