import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.Scanner;
public class Main {

/**
* @param args the command line arguments
*/
public static void main(String[] args)
{
Scanner scn=new Scanner(System.in);
  
String fileName;
  
System.out.print("Enter the filename: ");
fileName=scn.nextLine();
int count=0;
BufferedReader reader;
try
{
reader = new BufferedReader(new FileReader(fileName));
String line = reader.readLine();
while (line != null)
{
String word[]=line.split(" ");
count+=word.length;
  
line = reader.readLine();
}
reader.close();
System.out.println("\nTotal number of word in file "+fileName+" is :"+count);
}
catch (IOException e)
{
System.out.println("\nFile with filename '"+fileName+"' not found.");
