Every object has : state, behavior and identity - 
 Question Submitted By :: OOAD
I also faced this Question!!     Answer Posted By  
# 1

Identity : Every instance of a class should be unique. e.g.
in memory, every object has its own memory address. This is
part of the unique id, other than which a user can have
member variables uniquely identifying the instance of the class.

State : Every object, at any given point of time would have
to have a set of attributes defining its State.

Behavior : Every object based on its state and optionally
identity will have particular behavior.
