用java编写模拟斗地主洗牌发牌程序

package com.practice_1;


import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.TreeSet;


//
public class Pokers {


public static void main(String[] args) {
//创建一个HashMap集合
HashMap pokers = new HashMap();
//创建花色数组
String[] colors = {"♥","♠","♣","♦"};
//创建点数数组
String[] numbers = {"3","4","5","6","7","8","9","10","J","Q","K","A","2"};
//创建一副牌 花色+点数
int count = 0;
//创建一个存储索引的ArrayList集合
ArrayList indexs = new ArrayList();

for (int i = 0; i < numbers.length; i++) {
for (int j = 0; j < colors .length; j++) {
pokers.put(count, colors[j]+numbers[i]);
indexs.add(count);
count++;
}
}
indexs.add(count);
pokers.put(count, "小王");
count++;
indexs.add(count);
pokers.put(count, "大王");

//洗牌，洗的是编号
Collections.shuffle(indexs);
//发牌，发的是编号
//创建四个TreeSet集合分别存储三个人的牌和底牌编号
//（因为TreeSet集合是有序的，可以保证拿到的编号按从小到大排）
