Java PigLatin

[mcspud]

Hi i need help with a asighnment, i am supposed to take an existing pig latin transualater and modify it to deal correctly with capitals and punctuation, i am currently at a loss at what to do.
here is the class file:

import java.util.Scanner;

public class PigLatinTranslator
{
   public static String translate (String sentence)
   {
      String result = "";

      sentence = sentence.toLowerCase();

      Scanner scan = new Scanner (sentence);
      while (scan.hasNext())
      {
         result += translateWord (scan.next());
         result += " ";
      }

      return result;
   }
   private static String translateWord (String word)
   {
      String result = "";

      if (beginsWithVowel(word))
         result = word + "yay";
      else
         if (beginsWithBlend(word))
            result = word.substring(2) + word.substring(0,2) + "ay";
         else
            result = word.substring(1) + word.charAt(0) + "ay";

      return result;
   }
   private static boolean beginsWithVowel (String word)
   {
      String vowels = "aeiou";

      char letter = word.charAt(0);

      return (vowels.indexOf(letter) != -1);
   }
   private static boolean beginsWithBlend (String word)
   {
      return ( word.startsWith ("bl") || word.startsWith ("sc") ||
               word.startsWith ("br") || word.startsWith ("sh") ||
               word.startsWith ("ch") || word.startsWith ("sk") ||
               word.startsWith ("cl") || word.startsWith ("sl") ||
               word.startsWith ("cr") || word.startsWith ("sn") ||
               word.startsWith ("dr") || word.startsWith ("sm") ||
               word.startsWith ("dw") || word.startsWith ("sp") ||
               word.startsWith ("fl") || word.startsWith ("sq") ||
               word.startsWith ("fr") || word.startsWith ("st") ||
               word.startsWith ("gl") || word.startsWith ("sw") ||
               word.startsWith ("gr") || word.startsWith ("th") ||
               word.startsWith ("kl") || word.startsWith ("tr") ||
               word.startsWith ("ph") || word.startsWith ("tw") ||
               word.startsWith ("pl") || word.startsWith ("wh") ||
               word.startsWith ("pr") || word.startsWith ("wr") ); 
   }
}

Which part is confusing you? What have you tried? What have you thought about trying?

From the forum rules:
Do provide evidence of having done some work yourself if posting questions from school or work assignments

Simply dumping your assignment here is not evidence of effort.

I guess i am not sure how to go about it. i have started to try some different aproaches but have always ended up not knowing how to do something, here is something i started to deal with captilization, its not finished though.

import java.util.Scanner;

public class PigLatinTranslator
{
   public static String translate (String sentence)
   {
      String result = "";

      Scanner scan = new Scanner (sentence);
      while (scan.hasNext())
      {
         result += translateWord (scan.next());
         result += " ";
      }

      return result;
   }
   private static String translateWord (String word)
   {
      String result = "";

      if (beginsWithVowel(word))
         result = word + "yay";
      else
	if (beginsWithCaps(word))
         if (beginsWithBlend(word))
            result = word.substring(2) + word.substring(0,2) + "Ay";
              
         else
            result = word.substring(1) + word.charAt(0) + "ay";
	 else
          if (beginsWithBlend(word))
            result = word.substring(2) + word.substring(0,2) + "ay";
              
          else
            result = word.substring(1) + word.charAt(0) + "ay";
      return result;
   }
   private static boolean beginsWithVowel (String word)
   {
      String vowels = "aeiou";

      char letter = word.charAt(0);

      return (vowels.indexOf(letter) != -1);
   }
   private static boolean beginsWithBlend (String word)
   {
      return ( word.startsWith ("bl") || word.startsWith ("sc") ||
               word.startsWith ("br") || word.startsWith ("sh") ||
               word.startsWith ("ch") || word.startsWith ("sk") ||
               word.startsWith ("cl") || word.startsWith ("sl") ||
               word.startsWith ("cr") || word.startsWith ("sn") ||
               word.startsWith ("dr") || word.startsWith ("sm") ||
               word.startsWith ("dw") || word.startsWith ("sp") ||
               word.startsWith ("fl") || word.startsWith ("sq") ||
               word.startsWith ("fr") || word.startsWith ("st") ||
               word.startsWith ("gl") || word.startsWith ("sw") ||
               word.startsWith ("gr") || word.startsWith ("th") ||
               word.startsWith ("kl") || word.startsWith ("tr") ||
               word.startsWith ("ph") || word.startsWith ("tw") ||
               word.startsWith ("pl") || word.startsWith ("wh") ||
               word.startsWith ("pr") || word.startsWith ("wr") ); 
   }
   private static boolean beginsWithCaps (String word)
   {
	return (word.startsWith ("A") || word.startsWith ("B") ||
	word.startsWith ("C") || word.startsWith ("D") ||

} 
}

okay so i got punctuation taken care of, but i am having troule getting caps to work, here is my program so far

import java.util.Scanner;

      {
         result += pun (scan.next());
         result += " ";

      }
	
	

      return result;
   }
   private static String pun(String s) {
    String result = "";
    int i = 0;
    while (i<s.length()) {

      while (i<s.length() && !isLetter(s.charAt(i))) {
        result = result + s.charAt(i);
        i++;
      }

      if (i>=s.length()) break;
