Im Aktions Ereignis-Listener oben ich diese JFrame ausblenden möchten, während es die anderen jFrames schafft. Ich habe versucht, das Jframe zu instanziieren und zu verstecken, aber das erstellt eine neue Instanz. Ich habe auch das "this.setVisible (false)" versucht, das auch nicht funktioniert.Java verstecken JFrame, die

1) Siehe [Die Verwendung mehrerer JFrames, gute/schlechte Praxis?] (Http://stackoverflow.com/q/9554636/418556) 2) Siehe [Erkennung/Behebung für die hängende, nahe Klammer eines Codeblocks ] (http://meta.stackexchange.com/q/251795/155831) für ein Problem, das ich nicht länger stören könnte. 3) Bitte lerne die übliche Java-Nomenklatur (Benennungskonventionen - z. B. 'EachWordUpperCaseClass',' firstWordLowerCaseMethod() ',' firstWordLowerCaseAttribute', es sei denn, es ist ein 'UPPER_CASE_CONSTANT') und benutze es konsistent. –
