扑克牌

package collection;

public class Cards implements Comparable<Cards>{

    String name;
    String number;
    public Cards(String name,String number){
        this.name=name;

}

package collection;

玩家

package collection;

public class Player {
    public String id;
    public String name;

    public Player(String id,String name){
        this.id=id;
        this.name=name;

比较大小用的winCard

package collection;

public class Winner implements Comparable<Winner>{

    String name;
    String number;
    String nameWinner;

    public Winner(String nameWinner,String name,String number){
        this.name=name;

    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((name == null) ? 0 : name.hashCode());
        result = prime * result + ((number == null) ? 0 : number.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (!(obj instanceof Winner))
            return false;
        Winner other = (Winner) obj;
        if (name == null) {
            if (other.name != null)
                return false;
        } else if (!name.equals(other.name))
            return false;

                return false;
        } else if (!number.equals(other.number))
            return false;
        return true;
    }

    @Override
    public int compareTo(Winner o) {
        // TODO Auto-generated method stub
        return this.number.compareTo(o.number);
    }
}

package collection;

import java.util.Comparator;
