Ruby Object Oriented Programming Example

Though the value of the attribute may vary among different objects.

Ruby object oriented programming example.

Even a class itself is an object that is an instance of the class class. In this tutorial you ll learn the fundamental concepts of oop for ruby an object oriented programming language wherein everything is an object. Programming languages have procedural programming functional programming and object oriented programming paradigms. Strings numbers and even true and false.

The attributes of a flower could be the color fragrance or even whether it has thorns. No curly braces are used and the end keyword is used to mark the end of a flow control block. We now have an object. A class is like the blue print of an object and describes the attributes and behavior of an object.

Class car def initialize name color name name color color end. 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. Array hash string. Prints ob2 example.

Sometimes we might need certain features of a class to be replicated into another class. Thus in the below example the file name is good dog rb and the class name is gooddog.

Ruby file names should be in snake case and reflect the class name. Every value in ruby is an object even the most primitive things.

How are you end end ob1 example. Each object of the class would share these attributes. Object oriented programming part ii. Class example def initialize end def prints puts hello fella.

This chapter will take you through all the major functionalities related to. For your own classes you have to use new to create objects. Take for an example a lily. Object oriented programming oop is a programming paradigm that uses objects and their interactions to design applications and computer programs.

But since these are built into ruby we get special syntax to create them. Array hash string. In the above code you can observe that we are creating two objects of class example. 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.

Ruby is a pure object oriented language and everything appears to ruby as an object. Instead of creating that attribute again we can inherit the attribute from the other class. Ruby is an object oriented language with some functional and procedural features. Object oriented programming in ruby set 1.
