Swing NetBeans nimmt ActionListener nicht an.

[florilu]

Ich wollte jetzt noch mal in die Swing Programmierung mit NetBeans reinkommen, und wollte eine Art "Eieruhrprogramm" machen, alles funktioniert bis auf den Start Button.

Der Fehlerhafte Code

    timer.addActionListener( new ActionListener() 
  {
    public void actionPerformed( ActionEvent e ) 
    {
      long now = System.currentTimeMillis();
      if ( now >= end )
      {
        remainingMinLabel.setText( "" );
        startButton.setEnabled( true );
        JOptionPane.showMessageDialog( null, "BING!" );
        timer.stop();
      }
      else
          remainingMinLabel.setText( (end – now) / 1000 + " Sekunden" );
    }
  } );

Ab ActionListener fangen die Fehler an.

Also fangen wir an

Der grundsätzliche Fehler lautet:

method addActionListener in class Timer cannot be applied to given types;
  required: ActionListener
  found: <anonymous ActionListener>
  reason: actual argument <anonymous ActionListener> cannot be converted to ActionListener by method invocation conversion
----
(Alt-Enter shows hints)

Bei dem Part:

else
          remainingMinLabel.setText( (end – now) / 1000 + " Sekunden" );

gibt er mir den Fehler aus:

method addActionListener in class Timer cannot be applied to given types;
  required: ActionListener
  found: <anonymous ActionListener>
  reason: actual argument <anonymous ActionListener> cannot be converted to ActionListener by method invocation conversion

illegal character: \8211

not a statement

';' expected

If-Else Statements Must Use Braces
----
(Alt-Enter shows hints)

Und der Compiler Fehler:

Hoffe jemand kann mir helfen

PS:
Bitte gebt mir keine Links zu irgendwelchen Tutorials, ich brauche direkte Hilfe und den verbesserten Code, und warum es fehlerhaft war.

Ok, eine Sache getan.

Dennoch danke für die Hilfe
