Hi, bin dabei Hangman zu programmieren. Aktuell habe ich mehrere Klassen für eine grafische Realisierung erstellt (Hangman als Konsolenversion habe ich bereits erfolgreich zum laufen bekommen).

Die Hangman.java startet das Programm, in diesem Fenster soll dann der Spieler Optionen auswählen und das Spiel starten können. Nun kommt mein Anliegen. Die Hangman.java besitzt eine Menge Panels (Ich bin froh das es so aussieht). Wenn der Spieler das Spiel startet soll aber kein neues Fenster geöffnet werden, sondern der Fensterinhalt neu geschrieben werden (Zur Veranschaulichung habe ich HangmanPlay.java geschrieben, so soll das Fenster danach aussehen). Ich hab Informationen darüber gefunden es entweder mit der repaint-Methode oder den CardLayouts zu machen. Was ist bei so vielen Panels zum empfehlen? Ich habe mich schon an das Probleme gewagt, hatte aber nur mäßigen Erfolg. Jetzt werden die vielen Panels zu einem echten Problem...
Ich wäre euch für Anregungen, Hilfe und anderen Kommentaren sehr dankbar. Einen schönen Abend noch

Gruß
