Day13-Abstract-Classes

Problem:

Objective
Today, we're taking what we learned yesterday about Inheritance and extending it to Abstract Classes.
Because this is a very specific Object-Oriented concept, submissions are limited to the few languages that use this construct.
Check out the Tutorial tab for learning materials and an instructional video!

Task
Given a Book class and a Solution class, write a MyBook class that does the following:

Inherits from Book
Has a parameterized constructor taking these 3 parameters:
1. string title
2. string author
3. int price
Implements the Book class' abstract display() method so it prints these 3 lines:
Title:, a space, and then the current instance's title.
Author:, a space, and then the current instance's author.
Price:, a space, and then the current instance's price.
Note: Because these classes are being written in the same file, you must not use an access modifier (e.g.: public)
when declaring MyBook or your code will not execute.

Solution:

// Declare your class here. Do not use the 'public' access modifier.
class MyBook extends Book {
    // Declare the price instance variable
        private int price;

    public int getPrice() {
        return price;
    }

    public void setPrice(int price) {
        this.price = price;
    }
    /**   
    *   Class Constructor
    *   
    *   @param title The book's title.
    *   @param author The book's author.
    *   @param price The book's price.
    **/
    // Write your constructor here
        MyBook(String title, String author, int price) {
        super(title, author);
        setPrice(price);
    }
    /**   
    *   Method Name: display
    *   
    *   Print the title, author, and price in the specified format.
    **/
    // Write your method here
        @Override
    void display() {
        // TODO Auto-generated method stub
        System.out.println("Title: " + this.title);
        System.out.println("Author: " + this.author);
        System.out.println("Price: " + this.price);
    }
}
// End class
