What is the impact of access modifiers on encapsulation in Java?

Access modifiers in Java (public, private, protected) control visibility and access to class members, enhancing encapsulation.

Can you explain how 'private' access modifier helps in encapsulation?

The 'private' modifier restricts access to class members, ensuring that they can only be accessed within the class itself, thus protecting the internal state.

What happens if I don't use any access modifier?

If no access modifier is specified, the default access level is package-private, meaning the member is accessible only within its own package.

How do 'protected' access modifiers differ from 'private'?

'Protected' allows access to subclasses and classes in the same package, while 'private' restricts access to the defining class only.

Can you give an example of encapsulation using access modifiers?

Sure! For instance, a class 'BankAccount' can have private fields like 'balance' and public methods to deposit or withdraw, ensuring controlled access.
