Task: Create 2 Java classes Book BookDemo → contains the main() method Instructions: First create a class called Book The class Book DOES NOT HAVE a main method Create instance variables for: title: a String that contains the title of the book. author: a String that contains the name of the author publisher: a String that contains the name of the publishing house numCopiesSold: an int that holds the number of book copies sold. This must be a nonnegative value. yearOfRelease: an int that contains the year of the book's release. Only consider books released during 1950 – 2020. Create the Default Constructor – sets everything to default values and has no parameters. Create a Parameterized Constructor – with 5 parameters Create Accessors and Mutators for each instance variable MAKE SURE THE MUTATORS CHECK FOR VALID VALUES! Create the following Methods toString(): returns a String that contains the values of all instance variables for a particular Book object. equals(): takes in another instance of a Book and returns true only if the both book objects contain the same values for all instance variables. Finally create a class called BookDemo This class DOES HAVE a main method Create at least 3 different types of books Test if the accessors, mutators, and other methods work as intended.
In java preferably eclipse
Task: Create 2 Java classes
Book
BookDemo → contains the main() method
Instructions: First create a class called Book
The class Book DOES NOT HAVE a main method
Create instance variables for:
title: a String that contains the title of the book.
author: a String that contains the name of the author
publisher: a String that contains the name of the publishing house
numCopiesSold: an int that holds the number of book copies sold. This must be a nonnegative value.
yearOfRelease: an int that contains the year of the book's release. Only consider books released during 1950 – 2020.
Create the Default Constructor – sets everything to default values and has no parameters.
Create a Parameterized Constructor – with 5 parameters
Create Accessors and Mutators for each instance variable
MAKE SURE THE MUTATORS CHECK FOR VALID VALUES!
Create the following Methods
toString(): returns a String that contains the values of all instance variables for a particular Book object.
equals(): takes in another instance of a Book and returns true only if the both book objects contain the same values for all instance variables.
Finally create a class called BookDemo
This class DOES HAVE a main method
Create at least 3 different types of books
Test if the accessors, mutators, and other methods work as intended.
Sample Output:
Creating the first book object!
Printing the default values of the first book object:
Book Title: title unknown
Author: unknown
Number of Copies Sold: 0
Year of Release: 2020

Number of Copies Sold: 500000000
Year of Release: 1997
Enter the title of the second book: Harry Potter and the Deathly Hallows
Enter the author of the second book: J K Rowling
Enter the number of copies sold: 8300000
Enter the year of release of the second book: 2007
Creating the second book object...
