Can anybody help me as to why my program with the appropiate thrown exceptions only displays arrays are different.

import java.io.DataInputStream;

import java.io.DataOutputStream;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

import java.util.Random;

public class FileArray {

public static void main(String[] args) {

// TODO Auto-generated method stub

final int SEED = 1000;

final int SIZE = 20;

final String filename = "numbers.dat";

Random rand = new Random(SEED);

double[] array1 = new double[SIZE];

for (int i = 0; i < SIZE; i++) {

array1[i] = rand.nextDouble();

}

writeArray(filename, array1);

double[] array2 = readArray(filename);

if (compareArrays(array1, array2)){

displayArray(array2);

}

else {

System.out.println("Arrays are different");

}

}//main

private static void displayArray(double[] numbers) {

// TODO Auto-generated method stub

for(double number : numbers){

System.out.printf("%,.3f ", number);

}

}

private static boolean compareArrays(double[] firstArray, double[] secondArray) {

// TODO Auto-generated method stub

boolean arraysEqual = true;

int i = 0;

// First determine whether the arrays are the same size.

if (firstArray.length != secondArray.length)

arraysEqual = false;

// Next determine whether the elements contain the same data.

while (arraysEqual && i < firstArray.length)

{

if (firstArray[i] != secondArray[i])

arraysEqual = false;

i++;

}

return arraysEqual;

}

private static double[] readArray(String filename) throws IOException {

// TODO Auto-generated method stub

FileInputStream is = null;

DataInputStream dis = null;

double[] arr = new double[1000];

is = new FileInputStream(filename);

dis = new DataInputStream(is);

// reading double values from the file

int i = 0;

while(dis.available()>0) {

double d = dis.readDouble();

arr[i++] = d;

}

return arr;

}

private static void writeArray(String filename, double[] numbers) {

// TODO Auto-generated method stub

FileOutputStream fstream = null;

try{

fstream = new FileOutputStream(filename);

}

catch (FileNotFoundException e){

System.out.println(e.getMessage());

return;

}

DataOutputStream outputFile = new DataOutputStream(fstream);

for (double number : numbers){

try {

outputFile.writeDouble(number);

}

catch (IOException e) {

System.out.println(e.getMessage());

}

}

try {

outputFile.close();

}

catch (IOException e){

System.out.println(e.getMessage());

}

}

}

This is the required output in java language
