Method Overriding in Inheritance

Method overriding in object-oriented programming (OOP) is the ability of a subclass to provide its own implementation of a method that is already defined in its superclass. This allows the subclass to customize the behavior of the method without modifying the original implementation.

Diagram:

Superclass (Parent)        Subclass (Child)
   |                            |
   |                            |
 Method                      Method (Overrides)
   |                            |
   |                            |
   V                            V
Implementation              Custom Implementation

Example1:

• Superclass (Parent): Shape
• Subclass (Child): Rectangle
• Method: CalculateArea()

The Shape superclass defines an abstract CalculateArea() method, which serves as a blueprint for calculating the area of different shapes. The Rectangle subclass overrides this method to calculate the area based on its specific formula (i.e., length × width).

This example demonstrates how different subclasses can inherit a common method from a superclass and provide their own custom implementation to suit their unique characteristics.

Example2:

• Superclass (Parent): Shape

• Subclass (Child): Circle

• Method: CalculateArea()

  The Shape superclass has an abstract CalculateArea() method. The Circle subclass overrides this method to calculate the area based on its specific formula (e.g., πr^2).
