Chapter 10.4, Problem 27STQ

 “EOFException”:

• The “EOFException” is thrown when the program try to read beyond the end of a file.
• When the user use the “ObjectInputStream” at that time the “EOFException” class can be used to test for the end of a file.
• The “EOFException” class is one of the sub class of “IOException” class. So every exception of type “EOFException” is also of type “IOException”.

 Example:

 Consider an example of “writeDouble” is as follows:

//include requried header files

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.ObjectInputStream;

import java.io.IOException;

import java.io.EOFException;

//definition of "ReadFile" class

public class ReadFile

{

    //definition of main method

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

    {

        //declare and set the value to the variable

        String filename = "input.dat";

        //try block

        try

        {

/*create an object for "ObjectInputStream" stream class*/

ObjectInputStream inputStream = new ObjectInputStream(new FileInputStream(filename));

            //display the statement

System.out.println("The " + filename +" file contains");

            //try block

            try

            {

                //check the condition

                while (true)

                {

/*read the input from the user*/

double x = inputStream.readDouble();

                    //display the numbers

                    System...
