当我尝试编译一个小程序时，我写了一个纸牌数组并打印出来的程序，我得到6个错误，所有这些都是“找不到符号”错误。有人可以检查我的代码并找到错误吗？谢谢。

编译输出:

6 errors

Deck.java:

package carddeck;
class Deck {
    public Deck () {
        deck = new Card[51];
        int cardcount = 0;
    }
     public void buildDeck () {
        for (Card.Rank rankit: Card.Rank.values()) {
            for (Card.Suit suitit: Card.Suit.values()) {
                this.deck[cardcount] = new Card(suitit,rankit);
                cardcount++;
            };
        };
    };
}

最佳答案

您在类中没有属性deck，尝试像这样添加它:

class Deck {
    private Card[] deck = null;
    public Deck () {
        deck = new Card[51];
        int cardcount = 0;
    }
//...
}
