Java and Object-oriented Programming - IT Assignment Help

Assignment Task

Task
The purpose of this first project is simply to refresh your knowledge of Java and object-oriented programming. You task is to create a package BookPrinting, which implements a class hierarchy as follows:
1.Create a base class called Book. It should keep track of the following data items (you need to decide on the data type for each data item):

• Title
• Author
• Publication Year
• Number of pages
• Medium (0 - printed hardcover, 1- printed softcover, 2- electronic, 3 - all)
• Number of copies printed
• Production cost (i.e. the sum of all production expenses such as licensing, royalties, printing cost, etc.)
• Sale price (i.e. what does the book sell for, e.g. $7.95/copy)
• Number of copies sold
• Number of positive reviews
• Number of negative reviews

The class should have appropriate constructors, getters, setters, and a PrintInfo() method.

2.Create a class Textbook, derived from Book. The class inherits everything from the parent class and adds the following data (and appropriate methods):
Field (e.g. “Computer Science”, “Biology”, etc.)
Topic (e.g. “Computer Architecture”, “Molecular Modeling”, etc.)

3.Create a class Novel, derived from Book. The class inherits everything from the parent class and adds the following data (and appropriate methods): Genre (i.e. “Sci-fi”, “Thriller”, etc.)

4.Create an interface called PublicationInfo, which declares methods:
CostEffective(): This method, when implemented in a class should return true if the book is cost-effective, i.e. if the funds received from the sale of the book exceeds the production expenses. Otherwise return false.
GeneratesInterest(): The method, when implemented in a class, should return true if the number of positive reviews exceeds the number of negative review and if the number of sales exceeds a certain threshold (for example, when implemented in the Textbook class, the threshold 80% of the copies printed, whereas for novels, the threshold should be set to a larger number, say 65% of the copies printed).
Both class Textbook and Novel should implement the methods of the PublicationInfo interface.

5.Create a driver class Bookshelf. The class should contain a main method, which:
Opens a file called “data.txt”. Each line in that file will contain data about one book. For example:
“OpenGL”, M. Turner, 2020, 498,  3, 14000, 14995, 5.65, 12412, 581, 233, Computer Science, Computer Graphics
The entries are comma-separated, and listed in the order in section 1 above.
