Ruby Object Oriented Programming Example

This chapter will take you through all the major functionalities related to.

Ruby object oriented programming example.

Every value in ruby is an object even the most primitive things. No curly braces are used and the end keyword is used to mark the end of a flow control block. Programming languages have procedural programming functional programming and object oriented programming paradigms. Let us understand object creation with the help of an example.

Take for an example a lily. In the above code you can observe that we are creating two objects of class example. Class car def initialize name color name name color color end. To comment we use the symbol.

These features are part of the class and each instance of the class i e. Ruby is an object oriented language with some functional and procedural features. How are you end end ob1 example. A class is like the blue print of an object and describes the attributes and behavior of an object.

Ruby is a pure object oriented language and everything appears to ruby as an object. Each object of the class would share these attributes. Array hash string. The attributes of a flower could be the color fragrance or even whether it has thorns.

Sometimes we might need certain features of a class to be replicated into another class. Object oriented programming part ii. Thus in the below example the file name is good dog rb and the class name is gooddog. But since these are built into ruby we get special syntax to create them.

Class example def initialize end def prints puts hello fella. 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. For your own classes you have to use new to create objects. Array hash string.

Object oriented programming oop is a programming paradigm that uses objects and their interactions to design applications and computer programs. 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. Instead of creating that attribute again we can inherit the attribute from the other class. Ruby file names should be in snake case and reflect the class name.

We now have an object. 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. In this tutorial you ll learn the fundamental concepts of oop for ruby an object oriented programming language wherein everything is an object. Array hash string.

Prints ob2 example. Strings numbers and even true and false. Object oriented programming in ruby set 1. The way objects are created in ruby is by calling a new method on a class as in the example below.
