I am writing a program where if the user clicks, it should draw a point. The following code does not seem to work properly. If I click, it draws a point but vanishes later on. I tried using paint and paint component but I am not able to use them. Please help!!

Please use the "Code" tags when posting code.

You can start with the Swing tutorial on Custom Painting for a working example that you can modify.

just remove repaint() in you method mousePressed() and try again.but it's not a good way.
if you want your points stay and not vanishes.you must save them in a collection .everytimes you press ,repaint all point which in you collection.

I think this discussion ought to be moved to our GUIs forum
 
Don't get me started about those stupid light bulbs.
