What are some real-world examples of overriding in programming?

Overriding occurs when a subclass provides a specific implementation of a method that is already defined in its superclass. A common example is in object-oriented programming with classes like 'Animal' and 'Dog'. The 'Dog' class can override a method like 'makeSound()' to return 'Bark' instead of the generic 'Animal sound'.

Can you give me another example?

Sure! Consider a class 'Shape' with a method 'area()'. If you have subclasses like 'Circle' and 'Rectangle', each can override 'area()' to provide their specific area calculation formulas.

What about in Java? Any specific examples?

In Java, the 'toString()' method is often overridden. For instance, if you have a class 'Person', you can override 'toString()' to return the person's name and age in a readable format.

Are there any downsides to overriding?

Yes, overriding can lead to issues like reduced performance if not done carefully, and it can also make code harder to understand if overused.
