排序规则类实现

package com.demo;

import java.util.Comparator;
/**

 *数字、花色比对（越靠后的牌越大）
 */
public class Compara implements Comparator<Poker>{
    @Override
    public int compare(Poker arg0, Poker arg1) {
        String color = "黑桃 红桃 梅花 方片";
        String numbers = "2 3 4 5 6 7 8 9 10 J Q K A";
        int result = numbers.indexOf(arg0.getName()) - numbers.indexOf(arg1.getName());
        if(result < 0){
            return -1;
        }else if(result > 0){
            return 1;
        }else {
            int result2 = color.indexOf(arg0.getHuase()) - color.indexOf(arg1.getHuase());
            if(result2 < 0){
                return -1;
            }else if(result > 0){
                return 1;
            }else{
                return 0;
            }
