Is it possible to convert a custom ArrayList to an to byte array? And if so how would I do that.

ResultSet rs = st.executeQuery(clientQuery);
            MovieTableBean mTB;

            ArrayList<MovieTableBean> moviesList = new ArrayList<>();
            while (rs.next()) {
                mTB = new  MovieTableBean(rs.getInt("movieId"),
                        rs.getString("movieName"),
                        rs.getString("description"),
                        rs.getInt("genreId"));
                moviesList.add(mTB);
            }

How can I convert

ArrayList<MovieTableBean>

to an array of bytes?

I could not find any other questions that answered this, if you know of one please comment the link. Thanks.

Mind to explain why do you need that? – xingbin Sep 01 '18 at 16:03
I want to sent the ArrayList through a OutputStream, but cannot do that in its current state – Mat Black Sep 01 '18 at 16:04
Just make sure your MovieTableBean is serializable – Alex Roig Sep 01 '18 at 16:05

sorry if this sounds stupid, but I am a noob in java, but why make it serializable. What will that help? – Mat Black Sep 01 '18 at 16:08
