2. This is an individual assignment so work submitted should be createddby you
4. Submit java files and the output of the program by adding into word/pdf file onBlackBorad

Develop an application which should generate a bill for the customer when customer buys at least 5 but at the most 10 different books (i.e., different titles) of different category i.e. fiction and nonfiction. Your application should ask the information about a book i.e. title and type. It should continue if user has a book to buy. Your application should use only single array of Book not one for each category. You should createe and use the following classes:

Createe anabstractclass namedBookwith the following features:

2. String type field for book's title
4. A double type field for book's price
6. Provide a constructor that requires the book title and sets the title of the book using the parameter
8. Provide get methods for each attribute i.e. for title and price
10. An abstract method named setPrice()
12. Provide toString() method to return the title and price of the book
14. Provide equals() method to compare two books. Two books will be same if title is same.

Createe two sub classes of Book:FictionBookandNonFictionBook. Each must include the following:

2. setPrice() method that sets the price for all FictionBooks to $24.99 and for all NonFictionBooks to $37.99
4. Write constructor for each subclass that include a call to setPrice() to set the price of book.
6. Override toString() method in each class to return "Fiction" or "NonFiction" with the title and price of the book.

Createe aBillclass with the following features:

2. String type field for customer name.
4. Array of Book, with maximum capacity of 10 to hold books purchased by customer.
6. Double type bill amount for the bill of customer
8. Parameterized constructor to createe a bill object with the customer's name
10. printBill() method to print the details of bill i.e. customer name, all the books purchased and bill amount.
12. addBook() method to add a book purchased by a customer to the book array and update the bill amount.

Createean Assignment4 class with the main() to do the following:

2. Get the name of customer from the user and createea bill object using it.

14. If user choose option 2, to display bill option then it should display the bill of the customer using the printBill() method.
16. If user choose the option 3 then it should terminate the application
18. Any other option should display, "Invalid Choice"
