ich diese Methode bin mit Daten von bekommen dbObjekt der Klasse Datenbank kann nicht in einem String konvertiert werden

aber ich habe diesen Fehler
‚‘ Abfangbare fatale Fehler: Objekt der Klasse Datenbank nicht in String umgewandelt werden könnte ‚‘

Ich habe die volle Klasse zum Thema :) – acharmat
