What are the common mistakes in using encapsulation and abstraction?

What are the common mistakes in using encapsulation and abstraction?

Common mistakes include not properly hiding data, overusing getters and setters, and confusing abstraction with inheritance.

Can you explain why overusing getters and setters is a mistake?

Overusing them can lead to exposing internal state, which breaks encapsulation and makes the code harder to maintain.

What is the difference between encapsulation and abstraction?

Encapsulation is about hiding the internal state and requiring all interaction to be performed through an object's methods, while abstraction is about simplifying complex systems by modeling classes based on essential properties.

How can I avoid these mistakes in my code?

To avoid these mistakes, focus on designing clear interfaces, limit the use of public accessors, and prioritize meaningful abstractions.
