Die Fehlermeldung ist folgende:
cannot find symbol
symbol : variable getName
location: class Muellmann
Er denkt getName sei eine Variable, dabei ist es ein Attribut.
Um es leichter zu verstehen habe ich mein Problem leichter dar gestellt, wenn ich nun die Klassen poste muss ich weiter ausholen.
Habe eine Methode in der Klasse MuellKunde, die Methode heisst fuellen():void
das ist der Qeullcode:
