Writing int [ ] Array in a file

Question

Hye
Can you tell me which Stream I can use to write an Integer Array (defined as int [ 7000]) in a file .txt
I want to write as a whole not one by one.
Thanks

Answer 1

import java.util.Vector;
import java.io.*;
public class Queue extends Vector {
  ** FIFO, first in first out
  Queue() {
  super();
void put(Object o) {
  addElement(o);
Object get() {
  if (isEmpty()) return null;
    Object o = firstElement();
    removeElement(o);
    return o;
Object peek() {
  if (isEmpty()) return null;
    return firstElement();
To serialize (save the Queue state to a file) :
public static void main(String args[]) {
  Queue theQueue;
  theQueue = new Queue();
  theQueue.put(new int[]{1, 2, 3, 4});
  theQueue.put("ABCDE");
  theQueue.put(new Integer(3));
  System.out.println(theQueue.toString());
  // serialize the Queue
  System.out.println("serializing theQueue");
  try {
      FileOutputStream fout = new FileOutputStream("thequeue.dat");
      ObjectOutputStream oos = new ObjectOutputStream(fout);
      oos.writeObject(theQueue);
      oos.close();
   catch (Exception e) { e.printStackTrace(); }
To unserialize (to load a previously saved Queue) :
public static void main(String args[]) {
   Queue theQueue;
   theQueue = new Queue();
   // unserialize the Queue
   System.out.println("unserializing theQueue");
   try {
    FileInputStream fin = new FileInputStream("thequeue.dat");
    ObjectInputStream ois = new ObjectInputStream(fin);
    theQueue = (Queue) ois.readObject();
    ois.close();
   catch (Exception e) { e.printStackTrace(); }
   System.out.println(theQueue.toString());    
}hope that helps
