我正在尝试创建一个对OOP友好的Java BlackJack游戏，以增进我的知识。

我碰壁了，我只是不知道该问题。想知道是否有人可以指出我的问题。

另外，在搜索了与此相关的主题之后，我发现人们一次又一次地说使用枚举会更有益，因为建议初学者这样做？还是我暂时应该坚持使用String数组。

谢谢。

我的代码：

public class BlackJack{

BlackJack() {
    Deck deck =  new Deck();
    deck.createDeck();
    System.out.println(deck.deckList);
}

public static void main(String[] args) {

    new BlackJack();


   }
}


public class Card{

private String valueCard;
private String suitCard;

public Card(String value, String suit) {
    this.valueCard = value;
    this.suitCard = suit;
}

public String getValue() {
    return valueCard;
}
public String getSuit() {
    return suitCard;
  }
}

import java.util.ArrayList;


public class Deck {

ArrayList<Card> deckList = new ArrayList<Card>();

String[] value = {"Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten",
        "Jack", "Queen", "King", "Ace"};
String[] suit = {"Hearts", "Clubs", "Spades", "Diamonds"};


Deck() {

    deckList = new ArrayList<Card>();

}

public void createDeck() {
    for (int i = 0; i < value.length; i++) {
        for (int x = 0; x < suit.length; x++) {
            Card card = new Card(value[i], suit[x]);
            deckList.add(card);

          }
      }
  }
}

编辑：目前我从println发出的输出是：[Card @ addbf1，Card @ 42e816，Card @ 9304b1等。。。]这是什么意思？

感谢您的时间。

编辑：将来也需要此答案的任何人：

添加：

    @Override
public String toString(){
    return valueCard + " of " + suitCard;
}
 }

到我的Card类，然后在Deck类中使用它：

import java.util.ArrayList;


public class Deck {

ArrayList<Card> deckList = new ArrayList<Card>();

String[] value = {"Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten",
        "Jack", "Queen", "King", "Ace"};
String[] suit = {"Hearts", "Clubs", "Spades", "Diamonds"};


Deck() {

    deckList = new ArrayList<Card>();

}

public void createDeck() {
    for (int i = 0; i < value.length; i++) {
        for (int x = 0; x < suit.length; x++) {
            Card card = new Card(value[i], suit[x]);
            deckList.add(card);
            card.toString();
        }
    }
}
}

枚举：公共类CardEnum {

public enum Rank { DEUCE, THREE, FOUR, FIVE, SIX,
    SEVEN, EIGHT, NINE, TEN, JACK, QUEEN, KING, ACE }

public enum Suit { CLUBS, DIAMONDS, HEARTS, SPADES }


}


public class Card{

private CardEnum.Rank rank;
private CardEnum.Suit suit;

public Card(CardEnum.Rank rank, CardEnum.Suit suit) {
    this.rank = rank;
    this.suit = suit;
}

public Rank getRank() {
    return rank;
}
public Suit getSuit() {
    return suit;
}

@Override
public String toString(){
    return rank + " of " + suit;
}
}
