Ruby Object Oriented Programming 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.

Ruby object oriented programming example. Ruby file names should be in snake case and reflect the class name. In the above code you can observe that we are creating two objects of class example. Each object of the class would share these attributes. Object oriented programming in ruby set 1.

Thus in the below example the file name is good dog rb and the class name is gooddog. 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. 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.

These features are part of the class and each instance of the class i e. For your own classes you have to use new to create objects. Ruby is an object oriented language with some functional and procedural features. 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.

Sometimes we might need certain features of a class to be replicated into another class. A class is like the blue print of an object and describes the attributes and behavior of an object. Prints ob2 example. Object oriented programming part ii.

No curly braces are used and the end keyword is used to mark the end of a flow control block. How are you end end ob1 example. Class example def initialize end def prints puts hello fella. Let us understand object creation with the help of an example.

But since these are built into ruby we get special syntax to create them. Strings numbers and even true and false. This chapter will take you through all the major functionalities related to. Array hash string.

Array hash string. Class car def initialize name color name name color color end. Instead of creating that attribute again we can inherit the attribute from the other class. The attributes of a flower could be the color fragrance or even whether it has thorns.

Inheritance is one of the solid fundamental characteristics of object oriented programming. 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. We now have an object.

Array hash string. Every value in ruby is an object even the most primitive things. Programming languages have procedural programming functional programming and object oriented programming paradigms. The way objects are created in ruby is by calling a new method on a class as in the example below.
