yup..dat is the only problem...i know this..but i dont know how to add it in jpanel in this code..
see i m just a starter in java so...dont know much

I suggest that you get rid of the generated code and start with a small class that extends JFrame. Create a class that extends JPanel and override the paintComponent method in that class.
Add your new class to the JFrame.
And go from there.

ok..will do this
