Ruby - OOP

Ruby is a 100% object oriented programming language. When i make this statement you may question me "Your now saying the Ruby is a 100% oop language, but you haven't create a even single object in your hello world demo? ". Here is the answer.

puts "Hello World";

When you run the above code a default main object is created on the memory and puts method is invoked with "Hello World" argument.

Now i briefly explain how to create your own class, method and object.

class MyClass

def saysomething

puts("Hello")

end

end

my_class = MyClass.new

puts my_class.class

my_class.saysomething

Not on the code

-----------------

* class declaration started by class MyClass and ends with end.

* methods are declared using def keyword following method name, ends with end.

* Object is created by invoking the new method of the class. new method is inherited from top most parent class.
