Challenge 1: Implement the Rectangle Class Using the Concepts of Encapsulation

Can you implement the rectangle class using the concepts of encapsulation? 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

You are given a partially completed code of a Rectangle class in the editor. Add two fields i.e. length and width and modify the default and parametrized constructors which assign parameters to the length and width fields of the Rectangle class. In the end, Implement the getArea() method which returns the area of the rectangle.


Calls the constructor by passing length and width.
Calls the `getArea()` method to return the area.


Returns the area of a rectangle.
