Question

Create the above hierarchy as follows”

Create Book class having above attributes provide getter, setters and toString() method also make netProfyt() which returns profit by (salePrice- costPrice), and getTax() method which calculates 30% tax on the profit gain above.

Now create EBook which extends Books class and have sizeMB and downloadSite as attributes provide a constructor which will set values of above attributes and attributes of parent class as well, Provide getters /setters also. Now rewrite the getTax() method which will calculate tax on profit 30% + Rs 200 (per EBook ).

Write a class PaperBook which has publication( String) YearOfRelease(String),Provide a constructor which set values of this class members as well as super class attributes.Provide getters/setters. Now rewrite getTax() method which will compute tax by adding Rs. 150 on 30% of profit gained.

Create Test class and make an arrayList of Books, set values, and then calculate profit and tax fpr each book in arraylist. Note Books can be EBooks and paperBook.

ArrayList<Book> books=new ArrayList<Book>();

EBook e=new EBook(“ Ivor Horton”,500,550,”Intro to OOP”,200);

PapaerBookpb=new PaperBook(“Nielson”,600,700,”Intro to SRE”,350);

books.add(e);books.add(pb);

After that using loop call getTax() and netProfit() method, you will see that it will call methods polymorphically depending on type of object calling the method.
