Object-oriented programming (OOP) has been around for decades. As the original object-oriented language, Java is a mainstay in the world of computer programming. 

Having a foundation in OOP Java concepts will allow you to write cleaner, more modular, and more reusable code, as well as make it easier for you to understand the codebases of different companies you might be interested in joining.

Starting with the basics and reviewing complex topics like inheritance and polymorphism, this course is filled with illustrations, exercises, quizzes, and hands-on challenges. You’ll walk away with an understanding of classes and objects behavior and be able to easily create simple, efficient, reusable and secure code.

# 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

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

## Sample Output

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



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.
