Question

我开始编写War（卡片游戏）并且方法已经实例化了我需要知道为什么我会一直收到这些错误。

import java.util.*;

public class CardGame {
    public static void main(String[] args) {

        CardDeck CardDeckA = new CardDeck();
        //creates a standard card deck with 52 cards 1 - 10, J, Q, K, A diamond, spade, club, heart


        //Card( int value, int suit)

        int[] player1 = new int[52];
        int[] player2 = new int[52];
        int a = player1.length;
        int b = player2.length;

        for (int i = 0; a <= 26; i++) {
            player1[i].deal(); //Error: int cannot be dereferenced
            //deal( int n):Deals n cards from the top of the CardDeck, returns Card[]
        }

        for (int j = 0; a <= 26; j++) {
            player2[j].deal();//Error: int cannot be dereferenced
        }
    }
}

您应该将方法称为

player = CardDeckA.deal(1)

而不是

player1[i].deal()

由于player1[i]是原始int，因此它没有方法。

deal会返回int[]，具体取决于您使用它的方式，我怀疑它会类似于：

player = CardDeckA.deal(26)

我一直得到错误：int无法解除引用。我如何解决它？
