This is a Java Programming.

-> Create a class ReadingMaterial.

b) Create a subclass of RM called Newspaper - should call superclass constructors.

c) Create a subclass of RM called Manga - should call superclass constructors.

d) Create a subclass of RM called Book - should call superclass constructors.

-> Create a class Book.

a) Create a subclass of Book called Textbook - should call superclass constructors.

b) Create a subclass of Book called Novel - should call superclass constructors.

-> Create a class ReadingFactory. ReadingFactory should create a newspaper, a manga, a textbook and a novel.

a) ReadingFactory should contain a method that demonstrates polymorphism by displaying the object sent to it. b) ReadingFactory should have an arraylist of all the instantiated objects - sort the collection, and then use the display method. c) Demonstrate casting an object back to its original data type (e.g. cast a ReadingMaterial back to a Novel.)

8) Be sure all methods and JavaDocs included.
