用集合模擬鬥地主的洗牌的發牌

模擬鬥地主的洗牌和發牌

1)創建一個牌盒
2)裝牌：點數和花色:String類型
3)洗牌
4)發牌
5)看牌

代碼

:

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

public class PokerDemo {
    public static void main(String[] args) {
    //創建一個牌盒（集合）
        ArrayList<String> array = new ArrayList<String>();
    //裝牌
        //創建花色數組
        String[] colors = {"♠","♥","♣","♦"};
        //創建點色數組
        String[] numbers = {"A","2","3","4","5","6","7","8","9",
                "10","J","Q","K"} ;
        //開始裝配
        for(String color : colors){
            for(String number : numbers){
                array.add(color.concat(number));
            }
        }
    //添加大小王：
        array.add("大王");
        array.add("小王");
    //洗牌：隨機置換
        Collections.shuffle(array);
        System.out.println(array);

    //發牌
        ArrayList<String> player1 = new ArrayList<String>();
        ArrayList<String> player2 = new ArrayList<String>();
        ArrayList<String> player3 = new ArrayList<String>();
        ArrayList<String> dipai = new ArrayList<String>();

        for(int x= 0; x< array.size();x++){
            if(x >= array.size()-3){
                dipai.add(array.get(x));
            }else if(x%3 == 0){
                player1.add(array.get(x));
            }else if(x % 3 == 1){
                player2.add(array.get(x));
            }else if(x % 3 == 2){
                player3.add(array.get(x));
            }
        }
        //看牌：
        lookPoker("玩家一",player1);
        lookPoker("玩家二",player2);
        lookPoker("玩家三",player3);
        lookPoker("底牌是",dipai);
    }

    public static void lookPoker(String name,ArrayList<String> array){
        System.out.print(name+"的牌是：");
        for(String s : array){
            System.out.print(s+" ");
        }
        System.out.println();
    }
}
