Question

Add the following private attributes: String publisher

String title
String ISBN
String imageName double price

Create getter/setter methods for all data types

Create a constructor that takes in all attributes and sets them

Remove the default constructor

Override the toString() method and return a String that represents the book object that is

formatted nicely and contains all information (attributes)

In the main class:

Create a main method that throws FileNotFoundException

Import java.io libraries

Import java.util.Scanner

Create a loop to read the file

Add and ArrayList to your main program to hold your books be sure to import java.util.ArrayList

Within your loop (each iteration)

Read a line of data into variables for publisher, title, ISBN, image name and price.

Instantiate a "Book" object using the constructor you created sending in the

information read from the file.

Add the book into the array list

Once your loop is complete, use a for each loop to print each book (using the book’s toString() method) in the ArrayList to the console.

       String line;

           //since we might have names containing spaces i used ','(comma) as delimiter in the text file
           String[] info = line.split(",");
           //store book information in their respective variables
