    person.setAge(22);
    person.setName("Ali");
     
    //write serializable object
    FileOutputStream fileOutputStream = new FileOutputStream("file.txt");
    ObjectOutputStream objectOutputStream  = new ObjectOutputStream(fileOutputStream);
    objectOutputStream.writeObject(person);
    objectOutputStream.flush();
    objectOutputStream.close();
    
    //read serializable object
    FileInputStream fileInputStream = new FileInputStream("file.txt");
    ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream);
    Person person2 = (Person) objectInputStream.readObject();
    objectInputStream.close();
