Question
Consider and abstract class called Entertainment
1) Define the Entertainment class – it must have at least two attributes and
one appropriate method (constructor and property methods do not count).
2) Define
two
additional
classes
which
both
inherit
directly
from
Entertainment – they must each have two attributes and one appropriate
method each (constructor, property methods, and overridden1) methods do
not count).
3) Using one of the derived classes demonstrate composition. The component
class must consist of two attributes, and one method (constructor and
property methods do not count).
4) Implement your design in a visual basics application
Note that your program should adhere to both encapsulation, abstraction, and modular
principles.

Expected Structure for UML please note the diagram is incomplete.
Expected code should be the same structure as the code:
Check the base class logic
Check the sub class logic (if missing)
Check that that there is Composition
