这是我的 BlackJackGui 类。这个课程就是问题所在。他们找不到符号“.dealcard”和“.shuffle” 我是否必须更改 Deck 课程，还是可以解决这个问题？感谢您的帮助。

Answer 1

DeckOfCards的方法名为getTopCard()和shuffleDeck()，而不是dealCard()和shuffle()。

更改

BJDeck.shuffle();

到

BJDeck.shuffleDeck();

和

dealerHand.addCard( BJDeck.dealCard() );

到

dealerHand.addCard( BJDeck.getTopCard() );

找不到“.dealcard”方法和“.shuffle”方法。
