Question

I need help with my code when I run my code running the wrong thing like this

After downSize() words.length=60003

wordCount=60003

vowelCount=206728

this is my code here

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

public class Project02
{
   static final int INITIAL_CAPACITY = 10;
   public static void main (String[] args) throws Exception
   {
       // ALWAYS TEST FIRST TO VERIFY USER PUT REQUIRED INPUT FILE NAME ON THE COMMAND LINE
       if (args.length < 1 )
       {
           System.out.println("\nusage: C:\\> java Project2 <input filename>\n\n"); // i.e. C:\> java Project2 dictionary.txt
           System.exit(0);
       }

       String[] words = new String[INITIAL_CAPACITY];
       int wordCount = 0;
       int vowelCount = 0;

       BufferedReader infile = new BufferedReader( new FileReader(args[0]) );
       while ( infile.ready() )
       {
           String word = infile.readLine();

           // # # # # # DO NOT WRITE/MODIFY ANYTHING ABOVE THIS LINE # # # # #

           if(wordCount==words.length)
           {
              words = upSize(words);
               System.out.println( "words.length after upSize: " + words.length ); // use this line
           }
           words[wordCount++] = word; //confused on this
           //now append the word onto the end of the array and increment wordCount

           //now examine every char in the word and every time you detect an a e i o or u, increment vowelCount
           for(int i=0;i<word.length();i++){
               if(word.charAt(i)== 'a'|| word.charAt(i)=='e'|| word.charAt(i)== 'i'|| word.charAt(i)== 'o'||word.charAt(i) =='u')
               {
               ++vowelCount; //is there a difference between ++vowelCount and vowelCount++?
               }
           }

           // # # # # # DO NOT WRITE/MODIFY BELOW THIS LINE IN MAIN # # # # #

       System.out.println( "After downSize() words.length=" + words.length + "\nwordCount=" + wordCount + "\nvowelCount=" + vowelCount );

       System.out.println( "The duplicate word is: " + findFirstDupe( words, wordCount ) );

   } // END main

   // RETURN AN ARRAY OF STRING 2X AS BIG AS ONE YOU PASSED IN
