当我尝试编译一个小程序时,我编写了一组卡片并打印它们,我得到6个错误,所有这些都是“找不到符号”的错误。有人可以查看我的代码并找到错误吗?感谢。
编译输出:

您的课程中没有属性deck
,请尝试添加:
class Deck {
private Card[] deck = null;
public Deck () {
deck = new Card[51];
int cardcount = 0;
}
//...
}

你如何访问甲板,它没有定义。
class Deck {
Card deck;
int cardcount;
public Deck () {
deck = new Card[51];
cardcount = 0;
}
