Ruby Object Oriented Programming Example

Object oriented programming oop is a programming paradigm that uses objects and their interactions to design applications and computer programs.

Ruby object oriented programming example.

Array hash string. 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. 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.

These features are part of the class and each instance of the class i e. Thus in the below example the file name is good dog rb and the class name is gooddog. Each object of the class would share these attributes. Strings numbers and even true and false.

Let us understand object creation with the help of an example. In the above code you can observe that we are creating two objects of class example. Array hash string. Programming languages have procedural programming functional programming and object oriented programming paradigms.

Take for an example a lily. 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. No curly braces are used and the end keyword is used to mark the end of a flow control block. Object oriented programming part ii.

But since these are built into ruby we get special syntax to create them. Sometimes we might need certain features of a class to be replicated into another class. Array hash string. Every value in ruby is an object even the most primitive things.

Ruby is an object oriented language with some functional and procedural features. For your own classes you have to use new to create objects. This chapter will take you through all the major functionalities related to. Though the value of the attribute may vary among different objects.

Prints ob2 example. Even a class itself is an object that is an instance of the class class. Class car def initialize name color name name color color end. We now have an object.

How are you end end ob1 example. Inheritance is one of the solid fundamental characteristics of object oriented programming. 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.

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. In this tutorial you ll learn the fundamental concepts of oop for ruby an object oriented programming language wherein everything is an object. To comment we use the symbol. The way objects are created in ruby is by calling a new method on a class as in the example below.
