A super class reference can be converted into a subclass
reference but this
subclass reference is not useful to call the methods of any
of the classes. This convention is known as Downcasting.
We can convert the subclass reference to a superclass
reference without using the cast operation compiler because
it will internally take care of the casting. This is known
as Upcasting.
