Slick2d - How can I rotate a polygon or any other shape ?

I would like to know how can i rotate a 2d polygon. I know that a polygon is made of vertices, so to rotate the polygon, i have to adjust the coordinates of all the vertices. But what if my polygon has 500 points?? :o I need an easier way of rotating a shape instead of adjusting the x and y of all the points one by one :persecutioncomplex: I read the slick documentation and found out that there is a Transform class in slick, I reseached it but i did not understand how to use it ::slight_smile: . From many hours I am searching google and youtube but not getting any useful stuff. All they talk about is 3d.
