Hm, there are plenty of ways to connect that classes. In your current 
interface it maybe useful to have the last value in your super class too.

class Dictionary {
   private List keys_;
   private List values_;
   private int last_position_;

   Dictionary() {
   this.keys_ = new List();
   this.values_ = new List();
   }
}



now you can do something like:

public String lookup(String s) {
   int i = keys.locate(s);
   return values.get(i);
}

or (the same but shorter):

public String lookup(String s) {
   retrun values.get(keys.locate(s));
}
