Add a timer to the lightbulb ON/OFF program such that the bulb
stays on for 10 seconds after the ON button is pushed and then goes
off. Put a new label on the lightbulb panel that counts
the number of seconds the bulb is on and displays the number of
seconds as it counts up from 0 to 10. THIS IS A JAVA PROGRAM. The
image above is what it should look like.
