translation in Java 2D

[me]

Hello

I would be very grateful if someone could advise as to how to perform a
translation (translate(...)) on a Graphics2D object, using the center of
the graphic object as the rotation point.

(I ask because the object is rotating, and I've only just today started
looking at this API).

Thanks very much

Regards

J

Here is the algorithm:

Translate by -center.x, -center.y
Rotate by theta radians
Translate by center.x, center.y
