JAVA入門第三季——最後練習題撲克牌

玩家類：

package playCards;

import java.util.ArrayList;
import java.util.List;

//建立物件玩家，玩家至少要有ID、姓名、手牌等屬性，手牌為撲克牌的集合

public class Players {
    public int id;
    public String name;
    public List handCards;
    public Players(Integer id,String name) {
        this.id = id;
        this.name = name;
        this.handCards = new ArrayList();
    }
}

卡牌類

package playCards;

//建立物件撲克牌，不考慮大小王
public class Cards {
    public String num;
    public String color;
    public Cards(String num, String color) {
        this.num=num;
        this.color=color;
    }
    public Cards() {

    }
    @Override
    public boolean equals(Object arg0) {
        // TODO 自動生成的方法存根
        return super.equals(arg0);
    }

}

遊戲類（含main方法）

package playCards;

import java.util.ArrayList;
import java.util.InputMismatchException;
import java.util.List;
import java.util.Random;
import java.util.Scanner;

public class PlayGame  {

    private Scanner console;
    public Players player1;
    public Players player2;

        cardsToSelect = new ArrayList();
        cardsToSelectNew = new ArrayList();
        console = new Scanner(System.in);
    }

//新增撲克牌
    public void addCards() {
        System.out.println("建立撲克牌");//預設花色大小：黑桃》紅桃》梅花》方片

第一次寫手記，個人基礎也不好，高階的方法用的很少，比大小的時候也是隻有用原來按大小建立的卡牌的位置來比大小，希望各位大佬多多指教。
