1. Что не так?
В методе readObject(ObjectInputStream in) поле stream должно быть
инициализировано новым объектом типа FileOutputStream с параметрами(fileName, true).public void writeObject(String string) throws IOException {
stream.write(string.getBytes());
stream.write("\n".getBytes());
stream.flush();
