Getting Polygon out of the Area

Question

Hi,
I have an Area and after some transformation I am trying to get the Polygon out of it.
Does anyone know the best way to do it? Here is my code snippet:
int[] tPointsX= {0, 0, 100};
int[] tPointsY= {0, 50, 50};
int tN= 3;
Polygon triangle = new Polygon (tPointsX, tPointsY, tN );
int[] sPointsX= {0, 100, 0, 100};
int[] sPointsY= {0 ,0, 50, 50};
int sN= 4;
Polygon square= new Polygon (sPointsX, sPointsY, sN );
Area a1 = new Area (triangle);
Area a2 = new Area (square);
a2.subtract (a1);
Polygon finalResult = a2. ...? // how to get the polygon from the a2 after it
// has been transformed
Thanks for any hints
-Tom

Area class implements Shape interface, so you really don't need a method like area.getShape()
