在JFrame中重複JLabel

我正在用JAVA製作UNO遊戲。我遇到重複標籤的問題。我有一個JFrame。其中有7個JPanel。每個JPanel都有一個JLabel。 JLabels存儲在另一個類的arrayList中。每個JLabel都有一個圖像。 arrayList裏面有重複的JLabel。我正在將JLabel隨機添加到JPanel中。但是，當調用重複的JLabel時，它會被跳過。請幫助。在JFrame中重複JLabel

甲板：

public class Deck { 
    private ArrayList<JLabel> cards;

所有'Components'只能有1個父項。您需要製作重複的JLabels – ControlAltDel

注意圖標可以共享，但是您必須爲每個面板創建一個單獨的標籤。 – camickr

Swing組件不能被多個父共享。

然而，Icon可以共享。

所以你的get()方法需要更改以獲得一個隨機Icon，而不是一個隨機標籤。然後，一旦您檢索到Icon，就會創建一個新的JLabel並將Icon添加到標籤。然後您將標籤添加到表單。
