    oout.writeLong(987654321L);
    oout.flush();
    oout.close();
    // create an ObjectInputStream for the file we created before
    ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));

    // read and print a long
    System.out.println(ois.readLong());

    // read and print a long
    System.out.println(ois.readLong());
