What is true about private fields of a class? They must be used with private methods. They are accessible from anywhere inside or outside of a class. They can never be used in a class. They can be accessed only by methods inside the class they are associated with.

You will define three objects class Person, BookAuthor, and Book.  Class Person involves a person's identity. Class BookAuthor involves a collection of books or book titles. Class Book involves the number of books in stock , book title and price. Design the three classes:   The classes must use an appropriate inheritance relationship.   Each class must have a constructor. Each class has at least two private data members and you must include accessors.  You must test your classes by creating a BookAuthor object and printing the Person, Book and BookAuthor values from a function you create inside of BookAuthor. Make sure you use the book object correctly and put it inside of BookAuthor. in pytgi

Use the Animal class file given on the final exam module. Use Inheritance and Polymorphism concepts to create the following classes and functions. Create the following classes that derive from the Animal class. Monkey Kangaroo Create a derived class named Spider Monkey whose base class is Monkey. Create constructors for each class. Create destructors for each class. All classes will have the following private instance fields, including Animal legs that will initialize to 0 boolean swim that will initialize to false; All classes will have the following polymorphic methods, including Animal getLegs( ) – this returns the number of legs the animal has makeSount( ) – this outputs the type of sound the animal makes makeSound( ) method will be a virtual function in the Animal class Create an exception in the getLegs( ) method that makes sure the number of legs are valid (only allow positive number amount of legs) Create a main method to demonstrate the all functions including the…
