Explain how a subclass can can access its parent classes private instance variables and methods.

What will be an ideal response?


A subclass can access private instance variables and methods of its parent class, but only indirectly. There
must be public methods that access the private data and methods directly. These public methods can then be called by the
subclass, which gives indirect access to the private variables and methods of the parent class.
