Mehrere Bildschirm Java Applet hat Tasten, die nicht funktionieren

Question

Ich mache ein Programm, das 2 Bildschirme, einen Titel und einen Spielbildschirm hat. Wenn der Benutzer auf "Wiedergabe" klickt, kann er mit dem nächsten Bildschirm fortfahren. Wenn jedoch auf dem nächsten Bildschirm der Benutzer versucht, den Knopf "Keep Going" zu drücken, passiert nichts. Ich möchte wissen, warum das so ist und ob es jemand reparieren kann. Danke, und hier ist mein Code:

Vielleicht sollten Sie einen genaueren Blick auf diese beiden Blöcke haben ...

JButton keepgoing = new JButton("kg", createImageIcon("keepgoing.jpg")); 
keepgoing.addActionListener(this); 
keepgoing.setActionCommand("kg"); 


JButton stopscore = new JButton("ss", createImageIcon("stopAndScore.jpg")); 
keepgoing.addActionListener(this); 
keepgoing.setActionCommand("ss"); 

Sehen Sie etwas komisch?
