Answer 1

Normalement, vous pouvez appeler label.setMinimumSize(new Dimension(width, height)) pour que quelque chose soit forcé à une taille. Je ne sais pas exactement ce que vous essayez de faire ici - votre SSCCE n'est pas tout ce que short.

Answer 2

Il y a de nombreux problèmes avec le code affiché:

a) N'utilisez pas de composants AWT dans une application Swing. Tous les composants utilisés doivent commencer par "J" (par exemple JLabel, JTextArea, JTextField)

b) Le code que vous avez posté a été copié à partir d'une ancienne applet AWT. Les applets Swing sont codées différemment. Commencez par lire la section du tutoriel Swing sur How to Make Applets pour un exemple de base. Par exemple, vous ne devez JAMAIS remplacer les méthodes update() ou paint() dans un JApplet ou JFrame ou JDialog.

c) Il n'est pas nécessaire de définir la taille d'un JLabel. L'étiquette sera automatiquement la taille de l'icône ajoutée.

Nettoyez votre code, puis publiez un code SSCCE (http://sscce.org) si vous avez toujours des problèmes. Je ne suis pas sur le point de regarder à travers une centaine de lignes de code pour comprendre où vous avez lu l'image et l'ajouter à une étiquette.
