What are some common mistakes when working with complex types in programming?

Some common mistakes include not understanding type hierarchies, misusing generics, and failing to handle null values.

Can you explain how misusing generics can lead to issues?

Sure! Misusing generics can lead to type safety issues, where you might accidentally pass the wrong type, causing runtime errors.

What about null values? How can they cause problems?

Null values can lead to null reference exceptions if not properly checked, which can crash your application.

Are there best practices to avoid these mistakes?

Yes, always validate inputs, use type assertions carefully, and leverage type-checking tools to catch errors early.
