Passing variable information between classes

This code works, I just want to know if the structure is good or bad?
I want to know your opinions on the best way to pass variable results
between classes.

If I write a class that calculates tax etc and I want to pass that result to another class to be used in an array or another calculation should I do it like this?

Code:

---


public class totalMe {

        private static String word;

        /**
        * @param args
        * @param word
        */
        public static void main(String[] args) {
               
        smallSum sm = new smallSum();
       
       
               
        System.out.print(sm.TheWord(word));       
               
               

        }

}


class smallSum{
       
        public String TheWord(String word){
               
        word ="did it work?";       
       
        return word;
               
               
        }
       
       
       
       

}

Yes, "information passing between the classes" looks good to me. But you should better to practice on Sun's code conventions.
