When we talk about Object-Oriented Programming (OOP), two big ideas come up: classes and objects.
To really get OOP, it’s important to understand these two concepts because they help us model things we see in the real world and how they interact with each other.
A class is like a blueprint or a guide for making objects. It tells us what features (called attributes) and actions (called methods) the objects will have.
For example, think about a class called Car. This class might have these attributes:
A class also tells us what actions are possible. These actions are called methods. For the Car class, the methods might include:
start(): This action starts the car.stop(): This action stops the car.drive(distance): This action drives the car a certain distance.An object is a specific example of a class. When we make an object, we’re creating a real version of the blueprint the class provides.
For instance, if we have the class Car, we could create an object named myCar. Here’s how that might look in code:
myCar = Car()
myCar.make = "Toyota"
myCar.model = "Camry"
myCar.year = 2020
In this case, myCar is a particular example of a Car, with its own details for each attribute.
Let’s say we have a class called Dog that has attributes like name, breed, and age, along with actions like bark() and fetch(). You can create different objects, such as myDog and neighborDog, each with their own unique information:
myDog = Dog("Rex", "Labrador", 5)
neighborDog = Dog("Buddy", "Beagle", 3)
In simple terms, classes and objects are the building blocks of OOP. They help developers write code that is organized and reusable by representing real-world things and how they work together.
