#Help with Polygon Creation (Based on inputs from button panel)

So I am trying to get inputs from my code, which then creates a polygon with Input for sides, lengh,ID and color. I have created the main part in which the input is gained From a panel button. The ID system might work, however I couldnot check if it works because of the main problem, actually drawing the polygon.

For Some reason I cannot seem to create an actual polygon at all, let alone based on the inputs. So im just looking for a bit of help with this. The drawn polygon should look like the figure below where I have labelled how
each of the attributes relate to it.

I also use intelliJ for my coding.
attached is code files as there is more files in use

Suppose you have n sides. every inner angle is 2pi / n radians.
So something like this should work:

double innerAngle = 2* Math.PI / n;
for (int i = 0; i < n; i++) {
  double x = cenX + Math.cos(i * innerAngle) * radius;
  double y = cenY + Math.sin(i * innerAngle) * radius;
}
#

the x and y coordinates are the vertices. Just draw lines between them.
