Class
Definition
A blueprint for creating objects in object-oriented programming.
Deep Dive
In object-oriented programming (OOP), a class serves as a blueprint or a template for creating objects. It defines the properties (attributes or data) and behaviors (methods or functions) that all objects created from that class will possess. A class doesn't occupy memory itself to store specific data; instead, it describes the structure and functionality that its instances (the objects) will have when they are created.
Examples & Use Cases
- 1A `Car` class defining properties like `color`, `make`, `model`, and methods like `startEngine()` or `accelerate()`
- 2A `User` class with attributes such as `username`, `email`, `password`, and methods like `login()` or `updateProfile()`
- 3A `Product` class specifying `name`, `price`, `description`, and functions like `addToCart()`
