Welcome to Day 13! Check out this video

(https://www.youtube.com/watch?v=xSQKDWTahvs&feature=youtu.be)reviewing abstract classes

(https://docs.oracle.com/javase/tutorial/java/IandI/abstract.html), or just

jump into the problem. It's important to understand Inheritance

(https://docs.oracle.com/javase/tutorial/java/IandI/subclasses.html) before

attempting this challenge.

Following is an example of abstract class in java:

abstract class Book{

String title;

String author;

Book(String t,String a){

title=t;

author=a;

}

abstract void display();

}

An abstract class is a class that cannot be instantiated, meaning you cannot

create a new instance of it. Attempting to instantiate an abstract class

(such as abstract class Book, provided for you in the editor) like so:

Book new_novel=new Book("The Alchemist","Paulo Coelho");

results in error: Book is abstract; cannot be instantiated. This type of class

is only meant to serve as a base or blueprint for connecting the subclasses

that inherit it.

To use an abstract class, you must create its subclass and then instantiate

the subclass. Any abstract methods declared in the abstract class (such

as abstract void display() in abstract class Book) must be implemented

by the subclass.

In the editor we have provided the abstract Book class and a Solution class.

In the Solution class we created instance of a class called MyBook. Your

task is to write just the MyBook class. The class MyBook mustn't be public.

Note: Since this is a very specific Object-Oriented topic, we have only

enabled a few languages for which abstract classes make sense. If you

don't find your favorite language, try to experiment with the provided

languages or come back for the upcoming challenges.

Input Format

Input from STDIN is already handled in the code given in the editor. MyBook's

constructor must have the following parameters: String title, String author,

and int price.

Output Format

The void display() method should print and label the respective title, author,

and price of the book's instance (with each value on its own line) like so:

Title: $title

Author: $author

Price: $price

Note: The $ is prepended to variable names to indicate they are placeholders

for variables.

Sample Input

The Alchemist

Paulo Coelho

248

Sample Output

Title: The Alchemist

Author: Paulo Coelho

Price: 248

public class Solution {

public static void main(String[] args) {

/* Instantiate a Scanner class to read standard input */

Scanner stdIn = new Scanner(System.in);

/* Read the title, author and price of the book */

String title = stdIn.nextLine();

String author = stdIn.nextLine();

/* Instantiate a book, passing the information for this book */

Book new_novel = new MyBook(title, author, price);

/* Display the information for this book */
