到目前为止，我正在努力创建一个 JAVA 版本的 uno，我的老师称之为“Singles”。目前，我只是想获得一个可以移除卡片的工作套牌。
不过，我目前的问题是，当我移除一张卡时，没有任何更新。它根本不会重绘。我不知道为什么。
这是面板和框架类。
控制板：

//private static Deck myDeck = new Deck(); //Get a deck!
public CardPanel(Card myOtherCard){
this.setSize(100,150);
this.setPreferredSize(new Dimension(100,150));
myCard = myOtherCard;
//myCard = myDeck.getMainCard(0);

super.paintComponent(g);
