KeyListener wont work for me... please help.

starting from the ground up on a project for university, but i need to start with a keyListener, which i just cant get to work...

heres the demo i have put together of a key listener...

i get the following error :

"addKeyListener(java.awt.event.KeyListener) in java.awt.Component cannot be applied to ()..."

Code:

---


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

public class keyListenerDemo implements KeyListener
{

        public static void main(String [] args)
        {
                javax.swing.SwingUtilities.invokeLater(new Runnable()
                {
                        public void run()
                        {
                                createGUI();
                        }
                });
        }
       
        public static void createGUI()
        {
                JFrame frame = new JFrame("hello");
                       
                frame.addKeyListener(this); //ERROR ON THIS LINE!
                frame.setSize(700,700);
                frame.setVisible(true);
        }
   
   
    public void keyTyped(KeyEvent e)
    {
            System.out.println("got here");
    }
   
    public void keyPressed(KeyEvent e)
    {
            System.out.println("got here");
    }
   
    public void keyReleased(KeyEvent e)
    {
            System.out.println("got here");
    }
   
}

i really need help with this... thanks in advance :)

I think the problem is that you are trying to add (this) to the action listener but an actual instance of "this" hasn't been created.

Inside of run() try putting:

keyListenerDemo kld = new keyListenerDemo();
kld.createGUI();
