Object-Oriented Programming (OOP) is a great way to keep our code organized and allow us to use it again without rewriting everything. Let’s break it down simply.

1. Classes and Objects

In OOP, we use classes and objects.

Think of a class as a template for creating objects.

For example, let’s say we have a class called Car.

This class can have different features like:

• color
• model
• year

And it can have actions like:

• start()
• stop()

2. Encapsulation

Encapsulation means we can keep data and functions together in a class.

Once we create the Car class, we can make many Car objects with different features.

For example, we might have:

• myCar as a red 2022 Toyota
• friendCar as a blue 2019 Ford

Both of these cars are made from the same class but have different details. This makes it super easy to use the Car class again without changing any code for every different car.

3. Inheritance

Inheritance lets new classes borrow features from existing classes.

If we make a class called ElectricCar that comes from the Car class, the ElectricCar can use everything from Car but add its own special features too, like chargeBattery().

This saves us time and helps us avoid repeating ourselves.

4. Polymorphism

Polymorphism means we can use one method in different ways.

For example, if both Car and ElectricCar have a method called start(), we can call start() on any car, no matter what kind it is.

This makes our code more flexible and easier to work with.

Conclusion

In short, OOP makes it easier to reuse code by using encapsulation, inheritance, and polymorphism. This helps make our programming simpler and more efficient!
