Access modifiers in programming are keywords that set the accessibility or visibility of classes, methods, and other entities. They play a crucial role in encapsulation, which is a fundamental principle of object-oriented programming.

The correct identification of access modifiers includes Public, Private, Protected, and Default. Here's a breakdown of these terms:

  • Public: This modifier allows access from any other class in any package, promoting full visibility of the class or member.

  • Private: This restricts access to the defining class only. No other classes can access private members, which helps protect the internal state and behavior of a class from unintended interference.

  • Protected: Members declared as protected can be accessed by classes in the same package as well as by subclasses, even if those subclasses exist in different packages. This modifier provides controlled access while supporting inheritance.

  • Default (sometimes referred to as "package-private"): When no access modifier is specified, this level of access allows members to be accessible only within classes in the same package. This is useful for grouping related classes together, enabling them to interact without exposing members to the rest of the application.

The other options include terms that do not accurately represent access modifiers:
