[java] key listener wont work

Please start by defining how it "isn''t working."

when i press a key it doenst do anything, its supposed to print "pressed" "released" or "typed" when a key is pressed

This works:

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

	public class keyTest extends JPanel implements KeyListener {
		
        public static void main(String args[]) {                
        	JFrame frame=new JFrame("key test");                
        	keyTest kt=new keyTest();                
        	frame.getContentPane().add(kt);
        	frame.addKeyListener(kt); //added this               

        	frame.setSize(500, 500);                
        	frame.setVisible(true);       
        }       

		public keyTest() {               
			initKey();        
		}        
		
		public void initKey() {                
		//	this.addKeyListener(this);                

			System.out.println("keylistener added");        
		}        
		
		public void keyPressed(KeyEvent e) {                
			System.out.println("pressed");        
		}        
		
		public void keyReleased(KeyEvent e) {                
			System.out.println("released");        
			}        
			
		public void keyTyped(KeyEvent e) {                
			System.out.println("typed");        
		}
}

thank you very much

Well, I assume the reason was either A) the JPanel cannot recieve a keyListener or B) it cannot recieve focus to know it should be listening for keys, or C) the panel can do both, but you never focused on the panel.
