how do i count words in a text file using java-CodePudding

I'm trying to count the total of words in a file but java is giving the total of words per line. because I'm using .hasNextLine() it doesn't calculate the total of the lines no matter how I try it.is there a way to tell java to total each line and return the value of total word of the lines

import java.io.File;//import file class
import java.io.IOException;//import file class to handle errors
import java.util.Scanner;
import java.io.FileNotFoundException;

public class readingfromafile {
public static void main(String []args) {
{
 try{
 File myobj = new File("C:\\Users\\cse21-037\\Documents\\assighnment java\\100 words\\brain drain.txt");
 Scanner myReader  = new Scanner(myobj);
  while (myReader.hasNextLine()) {
  String data = myReader.nextLine();
  System.out.println(data);
 
  
        int count = 1;
         for (int i = 0; i < data.length() - 1; i  )
        {
            if ((data.charAt(i) == ' ') && (data.charAt(i   1) != ' '))
            {
                count  ;
            }
        }
                
        System.out.println(count);
        
    }

  }
 
  catch (FileNotFoundException e) {
  System.out.println("error 404");
  e.printStackTrace();
  }
  }
  }
  }

Use a global variable to store totalCount of words.

public static void main(String []args) {
 {
 try{
 File myobj = new File("C:\\Users\\cse21-037\\Documents\\assighnment java\\100 words\\brain drain.txt");
 Scanner myReader  = new Scanner(myobj);
 int totalCount = 0; 
  while (myReader.hasNextLine()) {
  String data = myReader.nextLine();
  System.out.println(data);


    int count = 1;
     for (int i = 0; i < data.length() - 1; i  )
    {
        if ((data.charAt(i) == ' ') && (data.charAt(i   1) != ' '))
        {
            count  ;
        }
    }
    totalCount = totalCount   count;
    System.out.println(count);     
   }
  }
    catch (FileNotFoundException e) {
    System.out.println("error 404");
   e.printStackTrace();
  }
  }
 }
 }

It should work.

I'd do it like this:

package stackoverflow;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

public class FileWordCounter {



    public static void main(final String[] args) throws IOException {
        final String fileName = args != null && args.length > 0 ? args[0] : "/test/file";
        final String text = Files.readString(Paths.get(fileName));
        final String[] parts = text.split("\\W "); // use \\s  to split whole words, use \\W  to exclude non-word characters
        System.out.println("Got parts:\t"   parts.length);

        System.out.println("Counting words...");
        long counter = 0;
        for (final String part : parts) {
            if (part != null && part.trim().length() > 0) {
                System.out.println("\t["   part   "]");
                  counter;
            }
        }
        System.out.println("Counted words:\t"   counter);
        System.out.println("All done.");
    }



}
