Challenge 1: Implement an Abstract Method in a Base Class

Can you implement an abstract method of a base class? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first.

Problem Statement

There is a Book class which has an abstract method getDetails(), a parameterized constructor, and three protected fields:

  • name
  • author
  • price

Write a MyBook class that inherits from the Book class and has a parameterized constructor taking these parameters:

  • String title
  • String author
  • String price.

Implement the Book class getdetails() method in the MyBook class so that it returns the MyBook details.

Input

Calls the constructor by passing name, author, and price.
Calls the `getDetails()` method to return the details of a book.

Output

Returns the details of a book.

Sample Input

Book myBook = new MyBook("Harry Potter", "J.k. Rowling", "100");

Sample Output

"Harry Potter, J.k. Rowling, 100"
