javase模拟斗地主洗牌和发牌(54)

1、使用Arraylist集合:

package com.it18zhang.day08;

import java.util.ArrayList;
import java.util.Collections;

public class PokerDemo {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        //牌合
        ArrayList<String> al = new ArrayList<>();
        String[] colors={ "♠", "♥", "♣", "♦" };
        String[] nums={ "A", "2", "3", "4", "5", "6", "7", "8", "9", "10",
                "J", "Q", "K" };
        for (String color : colors) {
            for (String num : nums) {
                String pai=color.concat(num);
                al.add(pai);
            }
        }
        al.add("大王");
        al.add("小王");
        ArrayList<String> p1 = new ArrayList<>();
        ArrayList<String> p2 = new ArrayList<>();
        ArrayList<String> p3 = new ArrayList<>();
        ArrayList<String> dipai = new ArrayList<>();
        Collections.shuffle(al);
        for(int i=0;i<al.size();i++){
            if(i>=al.size()-3){
                dipai.add(al.get(i));
            }
            else if(i%3==0){
                p1.add(al.get(i));
            }
            else if(i%3==1){
                p2.add(al.get(i));
            }
            else if(i%3==2){
                p3.add(al.get(i));
            }
        }
            lookPoker("p1", p1);
            lookPoker("p2", p2);
            lookPoker("p3", p3);
        }
    public static void lookPoker(String name,ArrayList<String> array){
        System.out.println(name+"的牌是：");
        for (String string : array) {
            System.out.print(string+" ");
        }
        System.out.println();
    }
}

2、使用HashMap集合

package com.lianxi1;

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

public class PokerDemo {

    public static void main(String[] args) {
        //牌盒，用于存放牌及编号
        HashMap<Integer, String> map = new HashMap<>();
        //集合，用于存放编号
        ArrayList<Integer> list = new ArrayList<>();
        //花色数组
        String[] colors={"♠", "♥", "♣", "♦"};
        //点数数组
        String[] nums={"3", "4", "5", "6", "7", "8", "9", "10", "J", "Q",
            "K", "A", "2", };
        int index=0;
        //分别存放牌及编号到集合中
        for (String color : colors) {
            for (String num : nums) {
                String pork=color.concat(num);
                map.put(index, pork);
                list.add(index);
                index++;
            }
        }
        map.put(index, "小王");
        list.add(index);
        index++;
        map.put(index, "大王");
        list.add(index);
        //洗牌(对编号集合进行）
        Collections.shuffle(list);
        //定义四个集合，用于存放底牌及玩家的手牌编号（由于排序，使用treeSet)
        TreeSet<Integer> dipai = new TreeSet<>();
        TreeSet<Integer> p1 = new TreeSet<>();
        TreeSet<Integer> p2 = new TreeSet<>();
        TreeSet<Integer> p3 = new TreeSet<>();
        //发牌，实际是编号
        for(int i=0;i<list.size();i++){
            if(i>=(list.size()-3)){
                dipai.add(list.get(i));
            }
            else if(i % 3==0){
                p1.add(list.get(i));
            }
            else if(i % 3==1){
                p2.add(list.get(i));
            }
            else if(i % 3==2){
                p3.add(list.get(i));
            }
        }
        //看牌
        lookPork("p1", p1, map);
        lookPork("p2", p2, map);
        lookPork("p3", p3, map);
        lookPork("dipai", dipai, map);
        
    }
    //对人的牌进行遍历
    public static void lookPork(String name,TreeSet<Integer> ts,HashMap<Integer, String> map){
        System.out.println(name+"的手牌是：");
        for (Integer key : ts) {
            System.out.print(map.get(key)+" ");
        }
        System.out.println();
    }
}
