JUSTIFYING TEXT! ANY help NEEDED

Question

hello,
I am writing a program for a high school java class, and our teacher is asking us to use the stringtokenizer to manipulate text being inputted(sp) by right-justifying it as an output. I have managed to use the stringtokenizer to seperate each word into an array, but I am a little confused as to how I should go about arranging my words with spaces using for loops etc.....hereis what i have so far:
import Keyboard;
import java.io.*;
import java.util.*;
class Justify {
// This method is passed a string 's' that contains several
// words separated by spaces. It creates an array called
// 'list' that contains each word in 's.'
public static void pullApartWords (String s, String[] list) {
     // Make 's' a StringTokenizer object
     StringTokenizer words = new StringTokenizer (s);
     // Create an array to hold the tokens
     // ** Note that we cannot do "new" here, or else it loses
     // the reference from the main method. **
     // list = new String[words.countTokens()];
     int count =0; // Counts each token
     // As long as there are more tokens in 'words,' put
     // the next token into the 'list'
     while (words.hasMoreTokens()) {
          list[count] = new String (words.nextToken());
          count++;
     // This method shows how the 'pullApartWords' method could be
// used. It creates a string, and calls the 'pullApartWords' method
// to create an array containing the words in this string. It
// then prints out the words in this string.
public static void main (String[] args)
throws java.io.IOException
     //String line= Keyboard.readString();
     System.out.println("Please enter text to justify");
     String line = Keyboard.readString();
     String sentence = "This is the sentence to be broken up into tokens.";
     String[] tokenArray; // This array will store the tokens
     tokenArray = new String[new StringTokenizer(line).countTokens()];
     // Takes each token in 'sentence' and puts it into the 'tokenArray'
     pullApartWords (line, tokenArray);
     // Output Section
     System.out.println ("The sentence is:");
     System.out.println (" "+line);
     System.out.println ();
     System.out.println ("There are "+tokenArray.length+" tokens in the sentence.");
     System.out.println ();
     //Print each token in the 'tokenArray'
     for (int i=0; i<tokenArray.length; i++) {
     System.out.println (" tokenArray["+i+"] = "+tokenArray);
     //for (int i= 0; i<tokenArray.length; i++)
          System.out.println(tokenArray[i])
any suggestions at all? anything would be helpful ...thanks

Here's something to play around with
import java.io.*;
import java.util.*;
class RightAlign
  String words[];
  public RightAlign()
    try
      BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
      System.out.println("Please enter text to justify");
      pullApartWords(br.readLine());
    catch(Exception e){}
    System.exit(0);
  public void pullApartWords (String s)
    StringTokenizer word = new StringTokenizer (s," ");
    words = new String[word.countTokens()];
    int count = 0;
    while (word.hasMoreTokens()) words[count++] = word.nextToken();
    display(s);
  public void display(String s)
    System.out.println ("The sentence is: " + s);
    System.out.println ("There are "+words.length+" tokens in the sentence.");
    String pad = "                         ";
    for(int i = 0; i < words.length; i++)
      System.out.println((pad+words).substring(words[i].length()));
public static void main (String[] args) {new RightAlign();}
