Java rotate, drag RoundRectangle2D problem please help me!!!

Question

Hi,
i have 2 program, the first program can rotate a RoundRectangle2D, and the secend program can create new RoundRectangle2D and drag them around.
The problem is that i want the rotate and the drag functions in one file, could any wone plese help me with this??
The code has been orginally written by phillips75. i have modified it.
The first program that rotates a Rectangle2D
