OnClick Image for Robot arm interface

[ApheoXAIO]

Hi Everyone
I have made a java program for a robot arm i am developing at uni with a team of guys and basically we have a web interface that sends an ASCI code 1-10 which the robot uses to perform specific functions. At the moment, i have a single image and using the "mouse capture" thing have managed to establish where the user is clicking and can use that to send the right signal.
I would like it so that when the user clicks on a part of the image for the robot arm the arrow changes color for the same duration as the "ThreadSleep" function goes for, that way, when someone clicks on one of the red arrows, the color changes to green (to show that it is moving) and then dissapears.
The Relevant code is here:

So my question is this
can i add a small image of a green arrow to go on top of the existing arrow when the user clicks the image, and then disapears after a 2 second delay?

Thanks for any responses!

Look at using a timer. Have a boolean flag for the paint to test whether to draw the arrow or not. Set the flag and start a Timer to awaken in 2 seconds to clear the flag and call repaint().

When posting code please enclose the code in code tags.
