 As you know, the "getGraphics()" method of a component
returns a "Graphics" object, but in many cases we need to
pass a "Graphics2D" object for "UI" processes.What is the
solution to this?
  I would be very gratefull if you send me a reply.
Thanks in Advance.

Just use type casting;

Graphics g = comp.getGraphics();
Graphics2D g2d = (Graphics2D) g;

This will work...

get the graphics objects(say graphics).
cast it to graphics2D objects, i.e.,
Graphics2D graphics2d = (Graphics2D) graphics;

Tank you for your kindness.
When I cast the object the "getFontRenderContex()" method
returns "null" value.
Is it because of casting?
Thanks in advance.
