Subject: Re: Class with Multi Constrcutor ( initialize )

Hello Mido,

There are several solutions to this problem.

The first one is this equivalent of vaargs in C language

def initialize(*args)
  args.each do |a|
    puts a.class.inspect
  end
end

The second one is to pass a hash or an array in parameter.

And the third is to put default values to your args:

def initialize(var1='', var2=0, var3=nil)
end

Hope i helped !

Kind regards
