OOP is like organizing this world by grouping similar things together and defining how they can interact. Instead of looking at the whole program, we focus on individual, self-contained units called objects.
A class is like a blueprint or a template for creating objects. An object is an instance, or a realization, of that blueprint. If a class is like a recipe, an object is a dish made using that recipe.
Class: Blueprint or template defining how an object should be created.
Object: An instance of a class, representing a specific thing or concept.
