Chapter 11.1, Problem 5SC

Explanation of Solution

Modified program:

//import the required header files

import java.io.File;

import java.io.FileNotFoundException;

import java.io.PrintWriter;

import java.util.Scanner;

//definition of "Test" class

public class Test

{

    //definition of main method

public static void main(String args[]) throws FileNotFoundException

    {

        //declare an object for "Scanner" class

        Scanner console = new Scanner(System.in);

        //get the input file name

        System.out.println("Input file:");

        String inputFileName = console.next();

        //get the output file name

        System.out.println("Output file:");

        String outputFileName = console.next();

        //declare a variable for "File" class

        File inputFile = new File(inputFileName);

        //declare an object for "Scanner" class

        Scanner in = new Scanner(inputFile);

        //declare an object for "PrintWriter" class

PrintWriter out = new PrintWriter(outputFileName);

        //declare the required variables

        double total = 0;

        int count = 0;

        //check the condition

        while(in.hasNextDouble())

        {

            //get the number from the user

            double value = in.nextDouble();

            //write it in the output file

            out...
