Here is a vowel method inserted in your code. That works. You can test
the rest like the length frequency.

[CODE]
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;

contains a
         // word of more than 100 characters

         }
         try {
             System.out.println("Enter the name of the file you wish to
read: ");
             String fileName = keyboardInput.readLine();
             FileReader file = new FileReader(new File("C:\\"
+fileName));

             {

                 numWords = numWords + words.length;
                 //
                 // Get number of vowels
                 vowelCount(line);

             {
                 // Print frequencies only up to the longest word
                 System.out.println(i + " :"+lengths[i]);
             }

             myFile.close();
         }
         catch(IOException iO)
         {
             iO.printStackTrace();
         }
     }
     public static void vowelCount(String target)
     {

         target = target.toUpperCase();

         for (int i = 0; i < 5; i++)
