表达式的类型必须是数组类型，但它已解析为Card

Question

我几乎完成了我的项目，我收到了这个错误：

“表达式的类型必须是数组类型，但它已解析为卡”

它的内容如下：deck[i] = newCard[i];以下是代码：

public class Deck
{
    //nextCard is used to keep count of which number card you are on in the deck.
    public int nextCard;
    private static final int DECK_SIZE = 52;

    //deck is used to represent an entire deck of cards.
    Card[] deck;
    //hand is a pair of 7 cards; is generated by dealACard();
    Card[] hand;

    /**
     * Default Constructor        
     *
     * <hr>
     * Date created: Feb 17, 2014 
     *
     * 
     */
    public Deck ( )
    {
        int i;
        nextCard = 0;

        for(i=0;i<DECK_SIZE;i++)
        {
            Card newCard = new Card(i);

            deck[i] = newCard[i];
        }
    }

我做错了什么？

Answer 1

删除数组括号以使用刚刚创建的Card实例

deck[i] = newCard;
                 ^

Answer 2

代码

deck[i] = newCard[i];

意思是：

Put the object at index i from my Array newCard into index i in my Array deck

你真正想要的是

Put this object newCard into index i in my Array deck

因为newCard不是数组，所以它是Card对象，它是您的数组deck所拥有的类型。只需将您的代码更改为：

deck[i] = newCard;
