Object-oriented programming (OOP) is a fundamental part of Ruby. This course explores OOP and how classes and objects can be used to develop more sophisticated software. Topics include the following: how to describe OOP; create a class and an object; classify objects by mutability; create and use class methods; use an external class or a module. Other areas covered are inheritance, polymorphism, encapsulation, method overriding, and overloading. You will learn how to investigate classes, and add access controls, raise and handle exceptions. Finally, as a review exercise, you will create and use classes and objects in a Ruby app.

Objectives

Ruby Full Stack Development: Object-Oriented Programming with Ruby describe object-oriented programming and how it is ingrained into Ruby create a class and create an object from that class in Ruby classify Ruby objects by their mutability and how that affects how they can be used add class methods and instance methods to a class in Ruby use a class or module from an external file in Ruby use inheritance, polymorphism, and encapsulation to extend or modify a class in Ruby use method overriding and method overloading to expand a class in Ruby use inspect and other calls to get information about classes and instances in Ruby add access controls to the methods of a class in Ruby to control which methods can be accessed raise exceptions within Ruby code handle exceptions in Ruby create and use classes and objects in a Ruby app
