Classical Object Oriented Concepts explain a class as a cookie cutter. A class allows you to create objects of the class.

A class can be considered as a specification of how the object of the class should look like and behave.

An object of the class is nothing other than a sequence of bytes at a specific memory location in the memory heap. Thus we can understand that an object is an instance of the class. We can see an illustration of a class.
