简易扑克牌游戏 定义了Constants、Main、Player、Poker四个类

这是我自己写的一个简易扑克牌游戏程序，纯手打，实现了视频中的功能，
如果各位有看不懂的地方可以提出来我会加注释后重新上传。

Constants.java

常数类，用来存放卡牌的花色以及数字信息

package com.imooc;

public class Constants {
    public static final String[] pokerNumber = {
            "A", "2", "3", "4", "5", "6", "7",
            "8", "9", "10", "J", "Q", "K"};
    public static final String[] pokerSuit = {
            "黑桃", "红桃", "梅花", "方片", 
    };
}

Main.java

程序的主函数

package com.imooc;

import java.util.Collections;
import java.util.InputMismatchException;
import java.util.List;
import java.util.Random;

        Main main = new Main();
        main.play();
    }

    private void play() {
        System.out.println("-------------创建扑克牌-------------");
        init();

        System.out.println("-----------扑克牌创建成功!-----------");
        System.out.println(pokers.toString());

        System.out.println("-------------开始洗牌--------------");
