Please find below the modified code.

CODE

=============

import java.io.*;

import java.util.Scanner;

public class WordCounter{

   public static int tocountWord(String str) {

       int count = 0;

       for(char ch : str.toCharArray()) {

           if(ch == ' ')

               count ++;

       }

       return count + 1;

   }

   public static void main ( String [] args ) {

       Scanner scanner = new Scanner( System.in );

       String userFileName;

       System.out.println( "Please enter the name of the file you want to read from. Please enter "count.txt"" );

       userFileName = scanner.nextLine();

       File file = new File ( userFileName );

       while( !file.exists() ) {

           System.out.println( userFileName + " does not exists. Please be sure to enter "count.txt"" );

           userFileName= scanner.nextLine();

           file = new File( userFileName );

       }

       Scanner fileToScan = null;

       PrintWriter fileToWrite = null;

       try {

           fileToScan = new Scanner(file);

           fileToWrite = new PrintWriter("countToWordCounter.txt");

       } catch (FileNotFoundException e) {

           // TODO Auto-generated catch block

           e.printStackTrace();

       }

       while( fileToScan.hasNext() ){

           fileToWrite.println(tocountWord(fileToScan.next()));

       }

       System.out.println( " Count has been counted and converted to WordCounter.txt " );

       fileToWrite.close();

       fileToScan.close();

   }
