Class is a template or a plan for creating objects.

For example: For construction of building we need a plan.
Without plan we can't construct building. Here plan acts as
class. Building acts as object.Using the same plan we can
build any number of building.

In the same way we can create any number of objects for the
same class.Class tell whats the object state and behaviour.
Basically class tells what the object should have.

Object is an real world entity, which has something and
which know something. It means ojects has state and
behaviour.State of the object is represented by instance
variable. Behaviours are representd by methods.
