Ruby Object Oriented Programming Example

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.

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. Inheritance is one of the solid fundamental characteristics of object oriented programming. No curly braces are used and the end keyword is used to mark the end of a flow control block. For your own classes you have to use new to create objects.

Even a class itself is an object that is an instance of the class class. These features are part of the class and each instance of the class i e. Object oriented programming part ii. Let us understand object creation with the help of an example.

Programming languages have procedural programming functional programming and object oriented programming paradigms. This chapter will take you through all the major functionalities related to. Each object of the class would share these attributes. Though the value of the attribute may vary among different objects.

Take for an example a lily. To comment we use the symbol. A class is like the blue print of an object and describes the attributes and behavior of an object. The attributes of a flower could be the color fragrance or even whether it has thorns.

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

The way objects are created in ruby is by calling a new method on a class as in the example below. Instead of creating that attribute again we can inherit the attribute from the other class. Array hash string. Ruby is an object oriented language with some functional and procedural features.

Ruby file names should be in snake case and reflect the class name. Class car def initialize name color name name color color end. How are you end end ob1 example. Object oriented programming oop is a programming paradigm that uses objects and their interactions to design applications and computer programs.

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. Every value in ruby is an object even the most primitive things. Class example def initialize end def prints puts hello fella. But since these are built into ruby we get special syntax to create them.

Prints ob2 example. Ruby is a pure object oriented language and everything appears to ruby as an object. Object oriented programming in ruby set 1. We now have an object.
