What is the difference between an object and a class?

1 Answer

Answer :

Classes and objects are separate but related concepts. Every object belongs to a class and  every class contains one or more related objects.
- A Class is static. All of the attributes of a class are fixed before, during, and after the  execution of a program. The attributes of a class don't change.
- The class to which an object belongs is also (usually) static. If a particular object belongs  to a certain class at the time that it is created then it almost certainly will still belong to  that class right up until the time that it is destroyed.
- An Object on the other hand has a limited lifespan. Objects are created and eventually  destroyed. Also during that lifetime, the attributes of the object may undergo significant  change.
