What are the common mistakes in encapsulation?

What are the common mistakes in encapsulation?

Common mistakes in encapsulation include exposing internal state, improper use of access modifiers, and lack of validation.

Can you explain why exposing internal state is a mistake?

Exposing internal state can lead to unintended side effects and makes it difficult to maintain and modify the code.

What are access modifiers and how should they be used?

Access modifiers define the visibility of class members. Use 'private' for internal use, 'protected' for subclasses, and 'public' for external access.

How can I validate data in encapsulated classes?

You can validate data by implementing setter methods that check the values before assigning them to the internal state.

Are there any best practices for encapsulation?

Yes, best practices include keeping your classes focused, using clear naming conventions, and ensuring that your methods are cohesive.
