Object class
Definition
The object class is a blueprint or template for creating objects in object-oriented programming. It defines the properties and behaviors that an object of that class will have.
Analogy
Think of the object class as a cookie cutter. Just like how a cookie cutter shapes dough into cookies with specific shapes, the object class shapes data into objects with specific properties and behaviors.

Encapsulation: Encapsulation is the bundling of data and methods within an object. It allows for better organization and control over access to the data.
Polymorphism: Polymorphism refers to the ability of an object to take on many forms. It allows different classes to be used interchangeably through inheritance or interfaces.
