Program will not read keyboard input.

-----------------------------------

My program won't let the user input any key commands, and I have no clue why. Everything should be working fine, but it doesn't.

public class Worms extends JFrame{
	
	public Worms(){
		super("Ohai Denny");
		setSize(645,505);
		setDefaultCloseOperation(EXIT_ON_CLOSE);
		Menu menu = new Menu();
    	setVisible(true);
    	setFocusable(true);
    	setResizable(false);
    	add(menu);

	}

RE:Program will not read keyboard input.

-----------------------------------

You need to add menu as a KeyListener as well.
After the line
add(menu);

add this line 
addKeyListener(menu);
