Object-Oriented Programming (OOP) is built upon four fundamental principles: 1. Encapsulation Encapsulation is the bundling of data (attributes) and methods that operate on that data within a single unit (object). It protects the data from external interference and misuse. 2. Inheritance Inheritance is the mechanism where one class (subclass or derived class) inherits the … Read more
