Object
In plain terms
An instance of a class holding state and behavior.
Going deeper
An object is a concrete instance created from a class, bundling its own data with methods that operate on it. It's a living example of a class.
Under the hood
Each object has its own state; identity distinguishes it from others even with equal data.
Examples
myCar = new Car(), instances, state + behavior, OOP, encapsulation.
Think of it like...
Like a specific car built from a blueprint, with its own color and mileage.
