    def __init__(self, title, author, price):
        self.title = title
        self.author = author
        self.price = price
        
    def display(self):
        print(f"Title: {self.title}")
        print(f"Author: {self.author}")

    javascript

    class MyBook extends Book{
    
    /**   
    *   Class Constructor
    *   
    *   @param title The book's title.
    *   @param author The book's author.
    *   @param price The book's price.
    **/
    // Write your constructor here
    constructor(title, author, price){
        super(title, author)
        this.price = price
        
    }
    /**   
    *   Method Name: display
    *   
    *   Print the title, author, and price in the specified format.
    **/
    // Write your method here
    display(){
        console.log(`Title: ${this.title}\nAuthor: ${this.author}\nPrice: ${this.price}`)
    }
// End class
}

    import java.util.*;

    abstract class Book { String title; String author;

    Book(String title, String author) {
    this.title = title;
    this.author = author;
}

abstract void display();

    }

    class MyBook extends Book{ int price; MyBook(String title, String author,int price){ super(title,author); this.price=price;

    }
 void display(){
   System.out.println("Title: " + this.title);
   System.out.println("Author: " + this.author);
   System.out.println("Price: " + this.price); 
}

    }

    public class Solution {

    public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    String title = scanner.nextLine();
    String author = scanner.nextLine();
    int price = scanner.nextInt();
    scanner.close();

    Book book = new MyBook(title, author, price);
    book.display();
}

    }
