You begin by instantiating a CubicCurve() instance. Next, the curve's attributes
are specified in any order by utilizing the object's setter methods and passing a single
value to each. Once you're finished specifying values on the CubicCurve() object,
you can add it to the scene graph using the following notation:

root.getChildren().add(cubicCurve);

The ice cream cone shape is created using the javafx.scene.shape.Path
class. As each path element is created and added to the Path object, each element is
not considered a graph node ( javafx.scene.Node ). This means they do not ex-
tend from the javafx.scene.shape.Shape class and cannot be a child node in a
scene graph to be displayed. When looking at the Javadoc (see ht-
tp://docs.oracle.com/javase/8/javafx/api/javafx/scene/
shape/Path.html ) , you will notice that a Path class extends from the Shape
class that extends from the ( javafx.scene.Node ) class, and therefore a Path is a
graph node, but path elements do not extend from the Shape class. Path elements ac-
tually extend from the javafx.scene.shape.PathElement class, which is
only used in the context of a Path object. So you won't be able to instantiate a
LineTo class to be put in the scene graph. Just remember that the classes with To as
a suffix are path elements, not real Shape nodes. For example, the MoveTo and
LineTo object instances are Path elements added to a Path object, not shapes that
can be added to the scene. The following are Path elements added to a Path object to
draw an ice cream cone:
