Habe ein kleines Problem

[pupkin]

Hier ist etwas Falsch:

 import javax.swing.*;
 import java.awt.event.*;
 import java.awt.*;

 class VideoRecorder extends JFrame {
    JButton play = new JButton("Play");
    JButton stop = new JButton("Stop/Eject");
    JButton rewind = new JButton("Rewind");
    JButton fast = new JButton("Fast-Forward");
    JButton pause = new JButton("Pause");
    JButton quit = new JButton("Stop");
    quit.addActionListener(this);
    
    public VideoRecorder() {
        super("Video Recorder");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel pre = new JPanel();
        FlowLayout dek = new FlowLayout(FlowLayout.CENTER);
        setLayout(pre);
        pre.add(play);
        pre.add(stop);
        pre.add(rewind);
        pre.add(fast);
        pre.add(pause);
        add(pre);
        setVisible(true);
    }  
        
    public static void main(String[] arguments) {
        VideoRecorder ise = new VideoRecorder();
        public void actionPerformed(ActionListener quit) {
            Object source = quit.getSource();
            if (source == quitButton) {
                quitProgram();
            }
        }
    }            
 }

Wenn ich es komplimiere erscheint folgender Fehler:
video1.java:31: illegal start of expression
public void actionPerformed(ActionListener quit) {
video1.java:37: ´;´ expected
}
video1.java:12: (identifier) expected
public void actionPerformed(ActionListener quit) {

Im Voraus Danke für Hilfe.

ein schönes Programm voller Fehler

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

class VideoRecorder extends JFrame implements ActionListener {
    JButton play = new JButton("Play");

    JButton stop = new JButton("Stop/Eject");

    JButton rewind = new JButton("Rewind");

    JButton fast = new JButton("Fast-Forward");

    JButton pause = new JButton("Pause");

    JButton quit = new JButton("Stop");

    public VideoRecorder() {
        super("Video Recorder");

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        quit.addActionListener(this);
        JPanel pre = new JPanel();
        FlowLayout dek = new FlowLayout(FlowLayout.CENTER);
        setLayout(dek);
        pre.add(play);
        pre.add(stop);
        pre.add(rewind);
        pre.add(fast);
        pre.add(pause);
        pre.add(quit);
        add(pre);
        setSize(600,300);
        setVisible(true);

    }

    public static void main(String[] arguments) {
        VideoRecorder ise = new VideoRecorder();
    }

    public void actionPerformed(ActionEvent event) {
        Object source = event.getSource();
        if (source == quit) {
            quitProgram();
        }
    }

    private void quitProgram() {
        System.out.println("i'm doing nothing");
    }
}
