Java Programming

hey guys, im new here its my first post
can you check out this code and tell why the key listener isn't working even though its implemented in exactly the same way that the mouse listener is

import java.awt.Color;
import java.awt.Dimension;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

import javax.swing.JPanel;


public class KeyListenerTest extends JPanel {
	
	

	public KeyListenerTest(){
		addKeyListener(new KeyListenerTestKeyListener());
		addMouseListener(new KeyListenerTestMouseListener());
		
		setBackground(Color.WHITE);
		setPreferredSize(new Dimension(400,400));
	}

	public class KeyListenerTestKeyListener implements KeyListener {

		public void keyPressed(KeyEvent arg0) {
			System.out.println("key pressed");

		}

		public void keyReleased(KeyEvent arg0) {}

		public void keyTyped(KeyEvent arg0) {}

	}
	
	public class KeyListenerTestMouseListener implements MouseListener {

		public void mouseClicked(MouseEvent arg0) {
			System.out.println("Mouse clicked");
		}

		public void mouseEntered(MouseEvent arg0) {}

		public void mouseExited(MouseEvent arg0) {}

		public void mousePressed(MouseEvent arg0) {}

		public void mouseReleased(MouseEvent arg0) {}

	}
	
}
