Ich bin ein Anfänger Java-Student arbeitet derzeit eine Gui-Aufgabe, die Berechnung der Einkäufe in einem Auto-Werk Garage umfasst, habe ich die Mehrheit abgeschlossen, aber ich bin fest, wenn eine Zusammenfassung Panel-Klasse machen.Die erste Code-Block ist meine Handler-Klasse ohne Probleme und die nächste ist die Zusammenfassung beide enthalten die erforderlichen importierten Pakete, ich kann nicht herausfinden, wie die Variablenwerte aus dem Handler auf die Übersichtsseite übergeben und sie den TextFields zuweisen . Ich entschuldige mich für das Format dieses Post es ist in der Tat meine erste. Bei Bedarf kann ich den Code aus meinen anderen Platten bietenGui Getter und Setter-Methode
