Long Time No See Ruby!

I studied Ruby 5 years ago.

At the time, I did know object oriented, c++, computer science.
Therefore, I did not understand good elements of Ruby.

Now, I have grown up at that time!
I see document of ruby.

I understand that ruby is good programming language!!

Ruby is ideal object oriented programming.

Next codes are that I wrote yesterday.

#!/usr/bin/ruby

=begin
  Hello !
  Tomorrow, I will install ruby-el in My laptop-machine.
=end

# define my class 
module My
  class Data
 attr_accessor :param, :index

 # This method is original method
    def output
     p @param
     p @index
    end

 # This method is constructor
 def initialize( index, param)
   @index = index
   @param = param
 end

  end
end


# Following codes main thread!
begin


data = My::Data.new(10, "Hello Ruby!!")

p data.param

end
