What are some real-world applications of method overriding in programming?

Method overriding is commonly used in object-oriented programming to provide specific implementations of a method in a subclass. For example, in a graphics application, a base class 'Shape' might have a method 'draw()', which is overridden in subclasses like 'Circle' and 'Square' to provide specific drawing logic.

Can you give me another example?

Sure! In a banking application, you might have a base class 'Account' with a method 'calculateInterest()'. The 'SavingsAccount' subclass could override this method to apply a different interest rate compared to a 'CheckingAccount' subclass.

How does overriding improve code maintainability?

Overriding allows for more flexible and maintainable code by enabling subclasses to provide specific behavior without altering the base class. This means you can add new features or modify existing ones without affecting other parts of the codebase.

Are there any performance implications of using method overriding?

Yes, there can be performance implications. Method overriding can introduce a slight overhead due to dynamic dispatch, where the method to be executed is determined at runtime. However, this is often negligible compared to the benefits of code flexibility and maintainability.
