Chapter 6, Problem 2E

Explanation of Solution

Program code:

file_read_tot_sum.java:

//import the required header files

import java.io.*;

import java.util.*;

//define a class file_read_tot_sum

class file_read_tot_sum

{

    //define a method evenNumber()

    public static void evenNumber()

    {

        //create an object of File

        File file = new File("10_Random.txt");

        //declare the required variables

        int sum=0,e=0,i,c=0;

        //try..catch

        try

        {

              //create the object of Scanner

            Scanner sc = new Scanner(file);

            //iterate a while loop to get the tokens

            while (sc.hasNextLine())

            {

                //reading tokens

                i = sc.nextInt();

                //increment the value of c by 1

                c++;

                //set the value of sum

                sum=sum+i;

                //checking even or odd

                if(i%2==0)

                    //increment the value of e

                    e++;

            }

            //print the sum
