Hi all,

This is exactly the question that I also wanted to ask, being new to
Ruby. I just registered 5 min ago and see almost the first post is the
very same probem.

What I want to do achieve is: I want a variable known throughout the
scope of the class but that is *not* always the same variable if you
instanciate a new object of the class (I like to achieve what the java
code above does).

For instance:

class Test
     var = 5

     def show
         puts var
     end

     def set(value)
         var = value
     end
end

test1 = Test.new
test1.set 10

test2 = Test.new
test2.set 20

test1.show
test2.show

Should show 10 and 20

How do I do this?
