将 object 分配给数组时需要的标识符
[英]identifier expected when assigning object to array
问题描述
将我在卡 class 中创建的对象分配给此数组时，获取预期的标识符。 有什么方法我必须设置数组构造函数来接受来自卡 class 的对象？ （更新了完整的 Main 类）
public class Main {
public Main(Card){ // Main constructor
是否需要在主构造函数的主体中添加一些内容以接受卡 class object？
}
public static void main(String[] args) {
Card card0 = new Card();
Card card1 = new Card();
Card card2 = new Card();
Card card3 = new Card();

card44, card45, card46, card47, card48, card49, card50, card51,
};
} }
下面是卡片 class 和构造函数：
public class Card {
int face = 0;
int suit = 0;
String faceText;
String faceValue;
String suitValue;
String suitText;
public Card() // card constructor, initially generates card number and suit
{
int face = 0;
int suit = 0;
Random generator = new Random();
face = generator.nextInt(13) + 1;
suit = generator.nextInt(4) + 1;
}
