     For context, from your original post:

     public static void main(String[] args) {
         // ...
         CollectVarsVisitor my_visitor = new CollectVarsVisitor();
         // ...
     }

My suggestion was to replace that one line in the middle with the two
I offered.  Now: Would either of those lines be inside a constructor?
(Hint: Is `public static void main(String[] args)' a constructor?)

     I'm going to repeat an observation I've already made elsethread:
Your grasp of Java is not yet firm enough to allow you to use the
language productively.  Back to the books!
