Java Program to Count the Number of Words in a File

import java.io.*;

public class Main 
{
   public static void main(String[] args) throws IOException 
   {
      // The input file
      File file = new File("myFile.txt"); 
      // Initialize the array of words
      String[] words = null;    
      // Initializes the counter of word to zero
      int count = 0;     
      // Create the File Reader object
      FileReader fr = new FileReader(file);
      // Create the BufferedReader object
      BufferedReader br = new BufferedReader(fr);    
      String str;
      // Read the contents of the file
      while((str = br.readLine()) != null)    
      {
         // Split the word using space
         words = str.split(" ");   
         // Increment the number of words 
         count = count + words.length;   
      }
      fr.close();
      System.out.println("Number of words in the file is:" +count);
   }
}
