Thereof, what is class visibility?
Visibility is a big part of OOP. It allows you to control where your class members can be accessed from, for instance to prevent a certain variable to be modified from outside the class. The default visibility is public, which means that the class members can be accessed from anywhere.
Furthermore, what is package visibility? Interfaces behave like classes within packages. An interface can be declared public to make it visible outside its package. Under the default visibility, an interface is visible only inside its package. The meaning of private protected was to limit visibility strictly to subclasses (and remove package access).
Also to know is, what are the visibility modes of derived class?
The accessibility of base class by the derived class is controlled by visibility modes. The three visibility modes are private, protected and public. The default visibility mode is private.
What is the default visibility of a class in Java?
Java: By default, the classes visibility is package private, i.e. only visible for classes in the same package. The class has no visibility defined like in Java. They are visible if you included them to the compilation unit.
