Ich habe viele Stunden an der Erstellung eines neuen JFram mit actionlistener gearbeitet, aber ich kann die Hintergrundfarbe meines Frames nicht ändern. Ich habe Panels, getContentPane() usw. ausprobiert. Momentan zeigt das Buy-Fenster alles an, was ich will, aber der Hintergrund ist weiß und ich habe versucht, es in Grau zu ändern.Ich erstelle einen neuen JFrame mit Aktion Listener, kann aber die Hintergrundfarbe nicht ändern
Unten ist mein Code.

ist es besser, nur Pakete mit allen Klassen zu importieren: import javax.swing. *; import java.awt.event. *; import java.awt. *; – GlacialMan
Standardfarbe aller Felder, und Rahmen sind grau, Farbe ändern – GlacialMan
Ich würde nicht mit @GlacialMan übereinstimmen, dass es besser ist, Pakete zu importieren. Wenn Sie Klassen importieren (und die IDE es automatisiert), ist es viel einfacher herauszufinden, wo Sie Verweise auf eine bestimmte Klasse mit 'git grep' oder ähnlichem haben. Natürlich, wenn Sie keine IDE haben, ist es wahrscheinlich mühsam, dies zu tun. – AlBlue
