For example, think of a class called "Car" that describes what a car is, such as its color, brand, and model.    - Now, an object is like a specific instance created from that blueprint. So, if you have a class "Car", you can create objects like "MyCar", "YourCar", each with their own unique characteristics. 2. **Encapsulation:**    - Encapsulation is like putting things in a box and only allowing access through certain ways.
