Error message Lat1 isn't abstract method

[ethaniel landfough]

I'm adding KeyListener and ActionListener to a JTextField class. Can i add KeyListener and ActionListener together.. And i got this error :

C:\Users\ERIE\Desktop\CROSSJAVA\Lat1.java:5: Lat1 is not abstract and does not override abstract method keyTyped(java.awt.event.KeyEvent) in java.awt.event.KeyListener
public class Lat1 extends JFrame implements KeyListener, ActionListener {

I wonder why this happen? Can someone help me pointed out, what did i do wrong?Thank's..

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

public class Lat1 extends JFrame implements KeyListener, ActionListener {

	final int ROWS = 12;
	
	final int COLS = 12;
	
	final static int topLeftNum[][]= {
		{-1, 1, 0, 2, 0, 0, 3, -1, 4, 0, 5, 0},
	    {6, 0, 0, 0, -1, -1, 0, -1, -1, -1, 0, -1},
	    {-1, 0, -1, 0, -1, 7, 0, 0, 8, -1, 0, -1},

	    {0, -1, -1, 12, 0, 0, 13, -1, 0, -1, -1, -1},
	    {0, -1, 14, -1, 0, -1, 0, -1, 15, 0, 0, 16},
	    {17, 0, 0, 18, 0, -1, 19, 20, 0, -1, -1, 0},
	    {0, -1, 0, 0, -1, 21, 0, 0, 0, -1, -1, 0},
	    {22, 23, 0, 0, -1, 0, -1, 0, -1,24, 0, 0},
	    {-1, 0, -1, 25, 0, 0, -1, 0, -1, 0, -1, -1},

Sorry, sorry. After i checked it again, i found what was wrong. I mismatch the typed of KeyTyped instead of keyTyped. So, it's already works now..
