What are access modifiers and how do they affect code design?

Access modifiers are keywords in programming that set the accessibility of classes, methods, and other members. They help in encapsulating data and controlling how it can be accessed or modified.

Can you give examples of different access modifiers?

Sure! Common access modifiers include 'public', 'private', 'protected', and 'internal'. Each one defines different levels of access for class members.

How do these modifiers impact code maintainability?

Using access modifiers properly enhances code maintainability by reducing dependencies and protecting the internal state of objects, making it easier to manage changes.

Are there any best practices for using access modifiers?

Yes, a best practice is to use the most restrictive access level that makes sense for a member. This minimizes exposure and potential misuse.
