Je suis un débutant à Java Swing/AWT et j'ai ce code après avoir travaillé pour une boîte de dialogue PopUp simple qui se ferme sur l'un des boutons JButtons cliqué, mais affiche réel foutu. Est-ce que quelqu'un a des suggestions sur quoi et comment résoudre?Pourquoi mon simple JFrame est-il bizarre?
