这是我BlackJackGui类。 这个类是问题所在。 他们找不到符号“.dealcard”和“.shuffle” 是否必须更改我的甲板课程还是可以解决问题？ 感谢您的帮助提前。

Answer 1

DeckOfCards有一个名为getTopCard()和shuffleDeck()，不dealCard()和shuffle()方法。

变化

BJDeck.shuffle(); 

到

BJDeck.shuffleDeck(); 

和

dealerHand.addCard(BJDeck.dealCard()); 

到

dealerHand.addCard(BJDeck.getTopCard());
