Answer / sandeep choudhary

inheritance is the ability for a class to inherit of
properties and the behavior from a parent class by extending it.

while containership is the ability of a class to contain the
another objects as member data.

if a class is extended, it inherits all the public and
protected properties and the behaviors and those behavior
may be overridden by the sub class.but if a class is
contained in another, container class does not have the
ability to add and modify of contained.
