Object-oriented programming (OOP) has been around for decades. As the original object-oriented language, Java is a mainstay in the world of computer programming. 

Having a foundation in OOP Java concepts will allow you to write cleaner, more modular, and more reusable code, as well as make it easier for you to understand the codebases of different companies you might be interested in joining.

Starting with the basics and reviewing complex topics like inheritance and polymorphism, this course is filled with illustrations, exercises, quizzes, and hands-on challenges. You’ll walk away with an understanding of classes and objects behavior and be able to easily create simple, efficient, reusable and secure code.

**Abstraction** in Object-Oriented Programming refers to showing only the essential features of an object to the user and hiding the inner details to reduce complexity. It can be put this way that the user only has to know *"what an object does?"* rather than *"how it does?"*.
