What are some common mistakes with polymorphism in OOP?

What are some common mistakes with polymorphism in OOP?

Some common mistakes include misunderstanding method overriding, not using interfaces properly, and failing to recognize the importance of type casting.

Can you explain method overriding and why it's important?

Method overriding allows a subclass to provide a specific implementation of a method that is already defined in its superclass, enabling polymorphic behavior.

What about using interfaces? How can that lead to mistakes?

Not implementing all methods from an interface in a class can lead to runtime errors. It's crucial to ensure that all required methods are defined.

How can I avoid these mistakes in my code?

To avoid these mistakes, always review your class hierarchies, use proper design patterns, and conduct thorough testing.
