Answer / jack
simple analogy for this quest is u declare int x;
and u ask diff between int and x;
Object is an instance of a class.......
--when an object of a class is created the memory for
that class is created...
--U can access the class members using the . operator in
your program....but u r not allowed to access the private
and protected members, which can be accessed by the member
functions only........
Class is the user defined datatype...which contains data
members and member functions.....

Answer / pankaj vashishta
Class is template for creating similar type of entities.
Class doesn't take memory space untill it contains static
members.
In a specific Class, you declare the attributes(field
variables) and its behaviour(functions).
But Class doesn't have any state and identity.
Objects are the real time entity which are created through
their template, thier class.
By real time entity, I mean they would occupy a memory
space in which they will save the values of its atrributes.
These values create a state of an object.
Since Object occupy a space in memory so they have unique
address in memory. This become the identity of an object.
For example : Pen is a class, which has weight and color as
its attribute. They may have behaviour like write().
Still they don't occupy a space in memory.
When I say My pen ,It will be an object of class Pen since
it will have some values for weight like 10 gm and color
like blue. This will occupy some memory to save these
values.
