What are public/private and protected in object Oriented Programming?

Broadly speaking, public means everyone is allowed to access, private means that only members of the same class are allowed to access, and protected means that members of subclasses are also allowed.

What is public/private and protected?

If the class member declared as public then it can be accessed everywhere. If the class members declared as protected then it can be accessed only within the class itself and by inheriting and parent classes. If the class members declared as private then it may only be accessed by the class that defines the member.

What is difference between protected and private?

The private modifier specifies that the member can only be accessed in its own class. The protected modifier specifies that the member can only be accessed within its own package (as with package-private) and, in addition, by a subclass of its class in another package.

What are public and private keywords?
