Can you explain when to use polymorphism in programming?
Polymorphism allows methods to do different things based on the object it is acting upon. It's useful when you want to define a common interface for different data types.
Can you give me an example of polymorphism in action?
Sure! In a shape class, you can have a method draw()
. Both Circle
and Square
classes can implement this method differently, but you can call draw()
on a shape reference without knowing the specific type.
What are the benefits of using polymorphism?
The main benefits include code reusability, easier maintenance, and the ability to introduce new classes with minimal changes to existing code.
Are there any downsides to using polymorphism?
Yes, it can introduce complexity and may lead to performance overhead due to dynamic method resolution.
