Thread: Making sure I answered this question completely.

Here's the question first of all: Change the PigLatinTranslator from chapter 4 so that its translatemethod is static. Change the PigLatin class so it invokes the method correctly.

Original PigLatinTranslator

import java.util.Scanner;
public class PigLatinTranslator
{
   //-----------------------------------------------------------------
   //  Translates a sentence of words into Pig Latin.
   //-----------------------------------------------------------------
   public String translate (String sentence)
   {
      String result = "";
      sentence = sentence.toLowerCase();
      Scanner scan = new Scanner (sentence);
      while (scan.hasNext())
      {
         result += translateWord (scan.next());
         result += " ";
      }
      return result;
   }
   //-----------------------------------------------------------------
   //  Translates one word into Pig Latin. If the word begins with a
   //  vowel, the suffix "yay" is appended to the word. Otherwise,
   //  the first letter or two are moved to the end of the word,
   //  and "ay" is appended.
   //-----------------------------------------------------------------
   private 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;
   }
//-----------------------------------------------------------------
   // Determines if the specified word begins with a vowel.
   //-----------------------------------------------------------------
   private boolean beginsWithVowel (String word)
   {
      String vowels = "aeiou";
      char letter = word.charAt(0);
      return (vowels.indexOf(letter) != -1);
   }
   //-----------------------------------------------------------------
   //  Determines if the specified word begins with a particular
   //  two-character consonant blend.
   //-----------------------------------------------------------------
   private 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") );
   }
}

Original PigLatin

import java.util.Scanner;
public class PigLatin
{
   //-----------------------------------------------------------------
   //  Reads sentences and translates them into Pig Latin.
   //-----------------------------------------------------------------
   public static void main (String[] args)
   {
      String sentence, result, another = "y";
      Scanner scan = new Scanner (System.in);
      PigLatinTranslator translator = new PigLatinTranslator();
      while (another.equalsIgnoreCase("y"))
      {
         System.out.println ();
         System.out.println ("Enter a sentence (no punctuation):");
         sentence = scan.nextLine();
         System.out.println ();
         result = translator.translate (sentence);
         System.out.println ("That sentence in Pig Latin is:");
         System.out.println (result);
         System.out.println ();
         System.out.print ("Translate another sentence (y/n)? ");
         another = scan.nextLine();
      }
   }
}

Editited PigLatinTranslator:

import java.util.Scanner;
public class PigLatinTranslator
{
   //-----------------------------------------------------------------
   //  Translates a sentence of words into Pig Latin.
   //-----------------------------------------------------------------
   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;
   }
   //-----------------------------------------------------------------
   //  Translates one word into Pig Latin. If the word begins with a
   //  vowel, the suffix "yay" is appended to the word. Otherwise,
   //  the first letter or two are moved to the end of the word,
   //  and "ay" is appended.
   //-----------------------------------------------------------------
   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;
   }
//-----------------------------------------------------------------
   // Determines if the specified word begins with a vowel.
   //-----------------------------------------------------------------
   private static boolean beginsWithVowel (String word)
   {
      String vowels = "aeiou";
      char letter = word.charAt(0);
      return (vowels.indexOf(letter) != -1);
   }
   //-----------------------------------------------------------------
   //  Determines if the specified word begins with a particular
   //  two-character consonant blend.
   //-----------------------------------------------------------------
   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") );
   }
}

Is this all I would need to do or is there more to it? Thanks in advance!

I didn't edit PigLatin but it runs perfectly.

Right, I replaced the new statement in PigLatin with PigLatinTranslator.translate(); but it gives me an error saying ican't apply () to translate.

yeah sure, I figured out i need to put in the parameter sentence, but NOW it says i need to initialize sentence.

import java.util.Scanner;
public class PigLatin
{
   //-----------------------------------------------------------------
   //  Reads sentences and translates them into Pig Latin.
   //-----------------------------------------------------------------
   public static void main (String[] args)
   {
      String sentence, result, another = "y";
      Scanner scan = new Scanner (System.in);
      PigLatinTranslator.translate(sentence);
      while (another.equalsIgnoreCase("y"))
      {
         System.out.println ();
         System.out.println ("Enter a sentence (no punctuation):");
         sentence = scan.nextLine();
         System.out.println ();
         result = PigLatinTranslator.translate (sentence);
         System.out.println ("That sentence in Pig Latin is:");
         System.out.println (result);
         System.out.println ();
         System.out.print ("Translate another sentence (y/n)? ");
         another = scan.nextLine();
      }
   }
}

Yep, all good now.
