PA Book

Week $8$

A Book has a title, author, publishing company $($all Strings$).$

Create a Java Class for Book:

Open your BlueJ project.

Add a new Java class named Book.

Define Class Attributes:

Inside the Book class, declare three private instance variables:

title:A string representing the book title.

author: A string representing the author's name.

publishingCompany: A string representing the publishing company.

Write Constructors:

Create two constructors for the Book class:

No$-$argument constructor:

Initialize all three attributes $($title$,$ author, and publishingCompany$)$ to empty strings.

Parameterized constructor.

Accept three arguments: title $($String$),$ author $($String$),$ and publishingCompany $($String$).$

Set the attributes based on the provided values.

Setter Methods:

Write setter methods to modify the book attributes:

setTitle$($String title$)$: Sets the book title.

setAuthor$($String author$)$: Sets the author's name.

setPublishingCompany$($String company$)$: Sets the publishing company.

Getter Methods:

Implement getter methods to retrieve the book details:

getTitle$()$: Returns the book title.

getAuthor$()$: Returns the author's name.

getPublishingCompany$()$: Returns the publishing company.

Example Usage:

In a separate class $($e$.$g$.,$ BookTester$),$ create a Book object using both constructors.

Set the attributes using setter methods.

Retrieve and print the book details using getter methods.

Remember to submit the code files $($Book$.$java and BookTester.java$)$ along with an output screenshot.

Note ${?}^{*****}$ You will find the java files in the project folder.
