java - 如何访问对象实例的数组索引

Question

美好的一天!

我想知道如何访问对象实例的数组索引。

我的代码如下:

public class PokerPlayer {

    private String name = null;
    private Card [] cardsOnHand = new Card[5]; 

    //getter and setter
}

我想要的是访问cardsOnHandArray[index]，以便我可以在另一个类上调用它并设置每个索引的值...

public class PokerGame {
      public static void main (String [] Args){
      PokerPlayer players []= new PokerPlayer[4];
      for(PokerPlayer player : players){
          for(int i =0; i<5; i++){
            //ACCESS cardsOnHand index i and store something on it...
          }
        }
    }
}

如有任何建议，我们将不胜感激。我怎样才能改进我的面向对象设计？预先感谢您

Answer 1

public class PokerPlayer {
...
public Card getCard(int index) {
  return this.cardsOnHand[index];
}

public void setCard(int index, Card card) {
  this.cardsOnHand[index] = card;
}
...
}

然后使用:

player.getCard(i);
player.setCard(i,new Card());
