Ich habe eine Klasse wo ich in eine Form ausfüllen muss. Nachdem ich das ausgefüllt habe, habe ich ein Button der das in ein JTabel hinzufügen soll jedoch ist dieser JTabel in einer anderen Klasse. Code habe ich schon geschrieben aber bin jetzt bischen verwirrt um erlich zu sein.
Ich weis jetzt nicht genau wie ich das machen muss.
