Question

Language: Java

To be able to code a class structure with appropriate attributes and methods. To demonstrate the concept of inheritance. To be able to create different objects and use both default and overloaded constructors. Practice using encapsulation (setters and getters) and the toString method.

Create a set of classes for various types of video content (TvShows, Movies, MiniSeries). Write a super or parent class that contains common attributes and subclasses with unique attributes for each class. Make sure to include the appropriate setter, getter methods and toString to display descriptions in a nicely formatted output. In addition to default constructors, define overloaded constructors to accept and initialize class data. When using a default constructor, use the setter from the main program to set values. Use a static variable to keep track of the number of objects in the video library. Display the number of items prior to listing them.

Data for movies should contain attributes for the title, release date, genre, studio, and streaming source (Netflix, Prime or Hulu).

Data for TvShow should contain the title, genre (same as others), date of the first episode, number of seasons, network, and running time.

Data for MiniSeries should include attributes for title, genre (same as others), number of episodes, running time, lead actor or actress.

Create a main driver class to create several objects of each type of video content. Use examples of both the default and overloaded constructors. Then display your complete video library with all fields.

All required variables are members of the class. Appropriate use of access specifiers. Encapsulation is implemented with setters and getters. Code is well structured and commented. Code meets standard Java conventions.

There is a default (no-arg) constructor, and an overloaded constructor for each video type. Objects created all have appropriate data content. A static variable is implemented and correctly counts objects created.

Methods are established in the class for all appropriate setters and getters. Inheritance is properly demonstrated with appropriate attributes, methods, and object instantiation.

The VideoLibrary class properly creates all the required objects and displays the entire video library with the number of items and all the data content in a nicely formatted output.
