When you start learning about Object-Oriented Programming (OOP), you'll soon come across classes and objects.
Think of a class as a blueprint for building objects. This blueprint shows the attributes (or features) and methods (or actions) that any object created from it will have.
Attributes are like the details that describe the state or characteristics of a class.
For example, if you have a class called Car, some attributes might be:
In a coding example, attributes are defined inside the class. Here is how it would look in Python:
class Car:
def __init__(self, make, model, year, color):
self.make = make
self.model = model
self.year = year
self.color = color
Methods are basically actions that the class can perform. They define what you can do with the object's attributes or how the class interacts with other objects.
Using our Car class example, methods might include:
You can write these methods in your class like this:
class Car:
...
def start_engine(self):
print("Engine started.")
def stop_engine(self):
print("Engine stopped.")
def drive(self):
print("Car is moving.")
Encapsulation is a key idea in OOP. It means putting together the data (attributes) and the methods that work with that data within one unit (the class).
This keeps parts of the object safe from outside access, which helps protect its state and keeps things organized.
Classes can also inherit attributes and methods from other classes. This helps keep things neat and organized.
For example, you could have a main class called Vehicle, and classes like Car, Truck, and Motorcycle could inherit from it.
Polymorphism is another interesting concept. It allows methods to have the same name in different classes but behave in different ways. This means you can use the same method name across various classes while having different outcomes.
In OOP, classes carefully define attributes and methods to create a model that reflects real-life things or ideas. This makes programming easier and more relatable, helping us understand it better.
