    double[] dbuf = { 65.56, 66.89, 67.98, 68.82, 69.55, 70.37 };

    FileOutputStream fos = new FileOutputStream("c:\\test.txt");

    DataOutputStream dos = new DataOutputStream(fos);

    for (double d : dbuf) {
      dos.writeDouble(d);
    }

    dos.flush();

    InputStream is = new FileInputStream("c:\\test.txt");

    DataInputStream dis = new DataInputStream(is);

    while (dis.available() > 0) {
      double c = dis.readDouble();
      System.out.print(c + " ");
    }

  }
}
