Java模拟斗地主洗牌发牌

方法一

package mv;

import java.util.*;

public class pk {
public static void main(String[] args){
List puke=new ArrayList<>();
String[] nums={“A”,“2”,“3”,“4”,“5”,“6”,“7”,“8”,“9”,“10”,“J”,“Q”,“K”};
String[] colors={“♥”,“♠”,“♣”,“♦”};

    for(String  color:colors){
        for(String num:nums){
            String pai=color+num;
            puke.add(pai);
        }
    }
    puke.add("大王");
    puke.add("小王");
    System.out.println(puke);
    //洗牌
    Collections.shuffle(puke);
    System.out.println(puke);
    //留3张牌
    List dipai=new ArrayList<>();
    Random random=new Random();
    for (int i=0;i<3;i++){
        int index=random.nextInt(puke.size());
        String pai=puke.remove(index);
        dipai.add(pai);
    }
    System.out.println(dipai);
    System.out.println(puke);
    //发牌
    List wwc=new ArrayList<>();
    List hll=new ArrayList<>();
    List tkh=new ArrayList<>();
    for(int i=0;i

}

                               HashMap pokers) {
