通常情況下，您可以撥打label.setMinimumSize(new Dimension(width, height))來強制大小。不確定你在這裏試圖做什麼 - 你的SSCCE並不全是short。

有許多問題與發佈代碼：

a）請勿在Swing應用程序中使用AWT組件。所有使用的組件應以「J」開頭（即JLabel，JTextArea，JTextField）

b）您發佈的代碼是從舊的AWT Applet複製的。 Swing Applet的編碼方式不同。首先閱讀關於How to Make Applets的Swing教程中的部分，作爲基本示例。例如，你絕不應該重寫JApplet或JFrame或JDialog中的update（）或paint（）方法。

c）不需要設置JLabel的大小。該標籤將自動成爲添加到其中的圖標的大小。

清理你的代碼，然後發佈SSCCE（http://sscce.org）如果你仍然有問題。我不打算瀏覽一百行代碼來確定你閱讀圖像的位置並將其添加到標籤中。
