Classes and objects from the essential part of Object-oriented programming, where a class can be considered as a construct that encapsulates a group of variables and methods; whereas, an object acts as member or instance of that class.
Lets us differentiate between these two:
|A class is a blueprint from which you can create the instance, i.e., objects.||An object is the instance of the class, which helps programmers to use variables and methods from inside the class.|
|A class is used to bind data as well as methods together as a single unit.||Object acts like a variable of the class.|
|Classes have logical existence.||Objects have a physical existence.|
|A class doesn't take any memory spaces when a programmer creates one.||An object takes memory when a programmer creates one.|
|The class has to be declared only once.||Objects can be declared several times depending on the requirement.|
