Java compilation error message.

Attempting to write my first java program that accepts user input.
When I add the listner events to the code it will not compile. Below
is the code along with the error message:


Code:

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

public class LottoEvent implements ItemListener, ActionListener,
Runnable {

}

Compilation Error message:

javac LottoEvent.Java: LottoEvent is not abstract and does not override
abstract method itemStateChanged(java.awt.event.ItemEvent) in
java.awt.event.ItemListener public class LottoEvent implements
ItemListener, ActionListener, Runnable

^

1 error
Any ideas on how to fix it would be appreciated.
