Unable to implement KeyListener

[Peter Nicholson]

Hi all,

firstly please advise if I've posted incorrectly as this is my first post.

Consider the following files :

Grandparent - public class

Parent - public abstract class extends Grandparent

Child - public abstract class extends Parent


I cannot change the class type or extensions in these files as these are a structure I did not create.

My issue is I am trying to create a KeyListener in a subclass of Child - I'll call Egg:

import java.awt.event. KeyListener

Egg public class extends Child implements KeyListener

I have tried various ways of achieving this:

- addKeyListener( keyListener)

- KeyListener listener = new KeyListener()

but end up with a "symbol not found ....KeyListener " when compiling.

I can create a working key listener in it's own separate file, I just can't seem to get it into this structure.

Any suggestions ?

And as I said please point out if I am posting incorrectly.

Thank you.

as Egg implements the KeyListener it can handle the KeyEvents.

So the following code should do the task:

addKeyListener( new Egg());

NOTE : if the component to which you want to make key event sensitive is there in the Egg class then write :
addKeyListener( this);

Pls ask if u ve any doubt......
