Is there any Java library for rotating an array of lines (start and endpoints) around a fixed rotation point? I can do it for a simple drawing but it is so much complicated calculus. If someone has already written this 2d graphics rotation library I am going to use it.

Is it called an affine transform? Is there some more theoretically simple mathematical method to do this?

It is easy to use the Path class, add to Path all of the lines and call Path.rotate(x, y, angle), where x,y is the center of rotation.
