| Aufgabe | In einem Dialogfenster soll man Klausuren selektieren können und zu jeder Klausur Studenten hinzufügen können.
In einem anderen Dialogfenster soll man beim selektieren der Klausuren die Studenten sehen können, die hinzugefügt wurden. |
Guten Tag,
ich habe zunächst zwei ArrayList erstellt in der Klasse Prufungsamt indem Klausur und Studentenobjekte enthalten sind.
Dann habe ich zwei Klassen erstellt "Klausuranmelden" und "Anmeldeliste" und es geschafft, dass die ArrayLists in Tabellen ausgegeben werden.
Weiter bin ich dann leider nicht gekommen.
Hier die Klasse Klausuranmelden:
