Having trouble with keys for a start menu on a game program

I am following a tutorial on how to make a platformer game and it got to the part where I am making a main menu for the game. I put:
addKeyListener(this);
and
setFocusable(true);
in the "GamePanel.java" class. I made a class for the menu called "MenuState.java" which is:
package pratformturtlestates;
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.event.KeyEvent;
import pratformturtle.GamePanel;
public class MenuState extends GameState {
private String options = {"Start", "Help", "Quit"};
private int currentSelection = 0;
protected MenuState(GameStateManager gsm) {
super(gsm);
}
public void init() {}
public void tick() {
}
public void draw(Graphics g) {
g.setColor(new Color(125, 20, 200));
g.fillRect(0, 0, GamePanel.WIDTH, GamePanel.HEIGHT);
for(int i = 0; i < options.length; i++) {
if(i == currentSelection) {
g.setColor(Color.GREEN);
} else {
g.setColor(Color.WHITE);
}
//g.drawLine(GamePanel.WIDTH / 2, 0, GamePanel.WIDTH / 2, GamePanel.HEIGHT);
g.setFont(new Font("Arial", Font.PLAIN, 72));
g.drawString(options[i], GamePanel.WIDTH / 2 - 75, 100 + i * 200);
}
}
public void keyPressed(int k) {
if(k == KeyEvent.VK_DOWN) {
currentSelection++;
if(currentSelection >= options.length) {
currentSelection = 0;
}
}else if(k == KeyEvent.VK_UP) {
currentSelection--;
if(currentSelection < 0) {
currentSelection = options.length - 1;
}
}
if(k == KeyEvent.VK_ENTER) {
if(currentSelection == 0) {
gsm.states.push(new Level1State(gsm));
} else if(currentSelection == 1) {
} else if(currentSelection == 2) {
System.exit(0);
}
}
}
public void keyReleased(int k) {
}
}
Whenever I run it the menu comes up with the purpleish background color and "start", "help", and "quit" but nothing happens when I hit the arrow keys or the enter key.

How canaddKeyListener(this);compile when your class does not implement the KeyListener interface? Also your keyPressed method,public void keyPressed(int k) {couldn't work since it is not a true override of KeyListener. The parameter should be aKeyEventobject, not an int.
