I'm working on code for a word scramble game in Java. I know the code itself is full of bugs right now, but my main focus is getting a vector of strings broken into two separate vectors containing hints and words. The text file that the strings are taken from has a colon separating them. So here is what I have so far.

public WordApp()
{

  inputRow = new TextInputBox();
  inputRow.setLocation(200,100);

  phrases = new Vector <String>(FileUtilities.getStrings());
  v_hints = new Vector<String>();
  v_words = new Vector<String>();

  textBox = new TextBox(200,100);
  textBox.setLocation(200,200);
  textBox.setText(scrambled + "\n\n Time Left: \t" + seconds/10 + "\n Score: \t" + score);

  hintBox = new TextBox(200,200);
  hintBox.setLocation(300,400);
  hintBox.hide();


Iterator <String> categorize = phrases.iterator();
  while(categorize.hasNext())
  {

    int index = phrases.indexOf(":");
    String element = categorize.next();

    v_words.add(element.substring(0,index));
    v_hints.add(element.substring(index +1));
    phrases.remove(index);
    System.out.print(index);
  }

The FileUtilities file was given to us by the pofessor, here it is.

import java.util.*;
import java.io.*;

public class FileUtilities 
{ 
   private static final String FILE_NAME = "javawords.txt";

   //------------------ getStrings -------------------------
   //
   //   returns a Vector of Strings
   //   Each string is of the form:  word:hint 
   //   where word contains no spaces.
   //   The words and hints are read from FILE_NAME
   //
   //
   public static Vector<String> getStrings (  ) 
   {
      Vector<String> words = new Vector<String>();

      File file = new File( FILE_NAME );

      Scanner scanFile;
      try
      {
         scanFile = new Scanner( file);
      } 
      catch ( IOException e)
      {
         System.err.println( "LineInput Error: " + e.getMessage() );
         return null;
      }
      while ( scanFile.hasNextLine() )
      {
         // read the word and follow it by a colon
         String s = scanFile.nextLine().trim().toUpperCase() + ":";

         if( s.length()>1 && scanFile.hasNextLine() )
         {
            // append the hint and add to collection
            s+= scanFile.nextLine().trim();
            words.add(s);
         }
      }  

      // shuffle
      Collections.shuffle(words);

      return words;
   } 
}
