Class Activity #$2$

In this activity, you will practice using arrays of objects in Java. This is a crucial concept as it combines understanding of both object$-$oriented programming and array data structures.

Background:

Imagine you are developing a software system for a library to track the books. Each book has attributes such as title, author, and year of publication.

Task:

Create a Java program that does the following:

Define a Book Class: Define a class named Book. It should have three private instance variables: title $($String$),$ author $($String$),$ and year $($int$).$ Include a constructor that allows you to set all three values at once. Also, include getter methods for each of these variables.

Display the Information about a book: Write a method $($in class Book$)$ that prints out the information of a book in the format: "Title by Author $($Year$)".$ The method should use the defined getter methods to access the private variables.

Create an Array of Book Objects: In your Main class, create an array named library that can hold $5$ Book objects.

Populate the Array: Fill the library array with five $(5)$ different Book objects, representing books of your choice. Initialize each Book with appropriate values for title, author, and year.

Display the Information about all books in the library: Write a method $($in class Main$)$ that takes the array of Book objects as a parameter and prints out the information of each book in the format: "Title by Author $($Year$)".$ Use the method to display all books information.
