比较方法

import java.util.Comparator;

public class CardComparator implements Comparator<Card>{

    @Override
    public int compare(Card o1, Card o2) {
        // TODO Auto-generated method stub
        int flag=0;

用户类

import java.util.ArrayList;

public class User {
    public int id;
    public String name;
    ArrayList<Card> handCard;
    public User(int id, String name) {
        super();
        this.id = id;
        this.name = name;
        handCard=new ArrayList<Card>();
    }
}

卡片类

public class Card {
    public String color;
    public String value;
    public Card(String color, String value) {
        super();
        this.color = color;
        this.value = value;
    }
    @Override
    public String toString() {
        return color+value ;
    }

}
