Title
Body
My code is throwing a NullPointerException, even though the object seems to properly exist. public class IrregularPolygon { private ArrayList<Point2D.Double> myPolygon; public void add(Point2D.Double aPoint) { System.out.println(aPoint); // Outputs Point2D.Double[20.0, 10.0] myPolygon.add(aPoint); // NullPointerException gets thrown here } } // Everything below this line is called by main() IrregularPolygon poly = new IrregularPolygon(); Point2D.Double a = new Point2D.Double(20,10); poly.add(a); Why is this happening?
