Once a class is defined, create number of objects belonging to that class.
These are used to implement the concept of Abstract Data Type(ADT).
The entire group of data and code of an object can be built as a user defined data types using
A class is a collection of objects of similar type.
Every object has its own value for each of its member variables. It shares the property name
or operations with other instances of the class. Thus ,class defines the characteristics and
