Shape and Method Overriding Problem Statement

Create a base class called Shape that contains a field named shapeType and a method printMyType.

Implement two derived classes:

Square: This class inherits from Shape and includes an additional field length. It has two methods, calculateArea that returns the area, and printMyType that outputs the type of the object.

Rectangle: This class also inherits from Shape and includes additional fields length and breadth. It includes the same two methods as Square.

Example:

Input:

// No specific input - This is an object-oriented programming task

Output:

Create a Square object with a length of 5:
Square
Area: 25

Create a Rectangle object with a length of 5 and breadth of 4:
Rectangle
Area: 20

Explanation:

In the main method, you should follow these steps:

Create an instance of the Square class with length = 5, use the printMyType method, and then call calculateArea.

Create an instance of the Rectangle class with length = 5 and breadth = 4, use the printMyType method, and then call calculateArea.

Constraints:

Ensure methods and variables are correctly encapsulated within the appropriate classes.

length and breadth are non-negative integers.

Note:

Focus on proper class design and method overriding principles. This problem emphasizes object-oriented programming concepts.
