Subject: Class Instanciation in loop

Hi everyone !

I am a beginner in Ruby and i am faced to a problem I do not understand.

I have two classes: Subset, Parser
Parser class parses an array (tab) which contains worlds from a file and
creates
Subset objects and adds them in two others arrays (@@good, @@bad).

This file looks like:
Good
{
  Subgp1
  {
     file1
  }
}
Bad
{
  Subgp2
  {
     file2
  }
}

For example :

j = tab.find_index("Bad")
i = 1
while i < tab.size do
  c = Subset.new(tab[i])
  i = i + 1
# This method parse is a subparser which parse the containning of SubgpX
# elements (here, file1 and file2) and put them in an Subset class
array.
  i = c.parse(tab, i)
  if tab[i] < j then
    @good << c
  else
    @@bad << c
  end
  i = i + 1
end

When I do a prettyprint of @@good and @@bad, @@good have the same
elements as
in @@bad, and others elements which should be in @@good disappeared.

Here is the output I have:

Good Tests :
  Subgroup name: Subgp2
    File: file2
Bad Tests :
  Subgroup name: Subgp2
    File: file2

Here is the output I want:

Good Tests :
  Subgroup name: Subgp1
    File: file1
Bad Tests :
  Subgroup name: Subgp2
    File: file2

Can you explain me why I have this behaviour in my script ?

Thanks by advance !
