Ruby Object Oriented Programming Example

Even a class itself is an object that is an instance of the class class.

Ruby object oriented programming example.

Each object of the class would share these attributes. Programming languages have procedural programming functional programming and object oriented programming paradigms. A class is like the blue print of an object and describes the attributes and behavior of an object. Class example def initialize end def prints puts hello fella.

Strings numbers and even true and false. Ruby is a pure object oriented language and everything appears to ruby as an object. The attributes of a flower could be the color fragrance or even whether it has thorns. This chapter will take you through all the major functionalities related to.

Ruby file names should be in snake case and reflect the class name. Object oriented programming oop is a programming paradigm that uses objects and their interactions to design applications and computer programs. In the above code you can observe that we are creating two objects of class example. Class gooddog end sparky gooddog new in the above example we created an instance of our gooddog class and stored it in the variable sparky.

Name def initialize name name name end end in this example ruby is able to both read and write the name instance variable since it was passed to attr reader and attr writer as a symbol. Thus in the below example the file name is good dog rb and the class name is gooddog. No curly braces are used and the end keyword is used to mark the end of a flow control block. Class car def initialize name color name name color color end.

In this tutorial you ll learn the fundamental concepts of oop for ruby an object oriented programming language wherein everything is an object. Object oriented programming part ii. Object oriented programming in ruby set 1. Sometimes we might need certain features of a class to be replicated into another class.

Take for an example a lily. Ruby is an object oriented language with some functional and procedural features. But since these are built into ruby we get special syntax to create them. Every value in ruby is an object even the most primitive things.

These features are part of the class and each instance of the class i e. How are you end end ob1 example. We will be using ruby since one of its defining attributes in addition to its elegant syntax and readability is how it implements oop techniques. For your own classes you have to use new to create objects.

Array hash string. Instead of creating that attribute again we can inherit the attribute from the other class. Prints ob2 example. Array hash string.

The way objects are created in ruby is by calling a new method on a class as in the example below. Array hash string. Though the value of the attribute may vary among different objects. Inheritance is one of the solid fundamental characteristics of object oriented programming.
