Object-Oriented Principles


OOP is governed by four main principles, as follows. Throughout the rest of this lesson, we will delve further into each of these principles:

  • Inheritance: We will learn how we can reuse code by using hierarchies of classes and inheriting behavior from derived classes

  • Encapsulation: We will also look at how we can hide the implementation details from the outside world while providing a consistent interface to communicate with our objects through methods

  • Abstraction: We will look at how we can focus on the important details of an object and ignore the other details

  • Polymorphism: We will also have a look at how we can define abstract behaviors and let other classes provide implementations for these behaviors
