Ich arbeite an einem javaFx Projekt, in dem wir @ verwenden müssObservableList, um Listener hinzuzufügen.ObservableList beinhaltet Personenmodell. Aber ich willGeschäf das GanzeObservableList Objekt in einer Datei durch Serialisierung. Aber es gibt mir eine Ausnahme. Ich habe auch Serialization für das Objekt Model implementiert, aber kein Glück. Gibt es eine Methode, um @ zu serialisiere ObservableList?

package com.company.Model;
