Ruby Object Oriented Programming Example

To comment we use the symbol.

Ruby object oriented programming example.

Array hash string. In the above code you can observe that we are creating two objects of class example. A class is like the blue print of an object and describes the attributes and behavior of an object. Ruby file names should be in snake case and reflect the class name.

Array hash string. Thus in the below example the file name is good dog rb and the class name is gooddog. 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 in ruby set 1.

Ruby is an object oriented language with some functional and procedural features. Sometimes we might need certain features of a class to be replicated into another class. We now have an object. 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. Every value in ruby is an object even the most primitive things. Class example def initialize end def prints puts hello fella. The attributes of a flower could be the color fragrance or even whether it has thorns.

For your own classes you have to use new to create objects. 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. These features are part of the class and each instance of the class i e.

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. Let us understand object creation with the help of an example. Programming languages have procedural programming functional programming and object oriented programming paradigms. 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. Even a class itself is an object that is an instance of the class class. Object oriented programming oop is a programming paradigm that uses objects and their interactions to design applications and computer programs. This chapter will take you through all the major functionalities related to.

Inheritance is one of the solid fundamental characteristics of object oriented programming. How are you end end ob1 example. Strings numbers and even true and false. But since these are built into ruby we get special syntax to create them.

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. Take for an example a lily. Prints ob2 example. Each object of the class would share these attributes.
