What are the best practices for using access specifiers in programming?

Best practices for access specifiers include using 'private' for internal methods, 'protected' for inherited methods, and 'public' for methods that need to be accessible from outside the class.

Why is it important to use access specifiers?

Using access specifiers helps encapsulate your code, protecting the internal state of objects and reducing the risk of unintended interference.

Can you give an example of when to use 'protected'?

Sure! Use 'protected' when you want to allow subclasses to access certain methods or properties while keeping them hidden from the outside world.

What happens if I don't use access specifiers?

If you don't use access specifiers, all members of a class are public by default, which can lead to poor encapsulation and increased risk of bugs.

Are there any exceptions to these best practices?

Yes, in some cases, such as with data transfer objects or certain frameworks, you might choose to expose more members for simplicity.
