I used the following code to make a circle. I need to make a button to save the coordinates of the circle. How do I extract these coordinates?

GraphicsContext gc = canvas.getGraphicsContext2D();
gc.setStroke(Color.BLUE);
Random rnd = new Random();
int x = rnd.nextInt((int) canvas.getWidth());
int y = rnd.nextInt((int) canvas.getHeight());
gc.strokeRect(x, y, 100, 100);

Put the coordinates and any other pertinent data into into an ArrayList of custom object or other collection, and then when needed, save the collection however you plan to save your data, be it database, xml, serialization,...
