public class Main {
  public static void main(String[] args) throws IOException {

    int[] i = { 123, 234, 454, 567, 789 };
    FileOutputStream fos = new FileOutputStream("c:\\test.txt");
    DataOutputStream dos = new DataOutputStream(fos);

    for (int j : i) {
      dos.writeInt(j);
    }
    dos.flush();// From: W  WW  . yI I B A I .c O M 
    InputStream is = new FileInputStream("c:\\test.txt");

    DataInputStream dis = new DataInputStream(is);
    while (dis.available() > 0) {
      int k = dis.readInt();
      System.out.print(k);
    }
  }
}
