What do you understand by private, protected and public?
In Java programming we use this to display the result: inheritance in private,protected,public etc. To know the concept of inheritance clearly you must have the idea of class and its features like methods, data members, access controls, constructors, keywords this, super etc. The private inheritance is used to define the private class in most restrictive, while public is the least restrictive. However the protected keyword allows visibility to a derived class in a different package.
