Hi,
ich will einen Clip Player mit einem Button erstellen. Es wird aber kein Fenster angezeigt und ich weiß nicht wieso. Ich höre immer nur den Clip. Die Buttons sind erstmal egal.
Habe in Zeile 31 ein JFrame erzeugt. Aber das funktioniert nicht.
Hier der komplette Code.
Wäre dankbar wenn mir jemand erklärt wie ich hier ein Fenster erzeugen kann.
