        try {
            ArrayList<String> lines = get_arraylist_from_file(f);
            for (int x = 0; x < lines.size(); x++) {
                System.out.println(lines.get(x));
            }
        } catch (Exception e) {
            e.printStackTrace();

        String[] tempList = s.split("&"); //This will give you this [title][ DVD]
        String title = tempList[0];
        String type = tempList[1].subString(1); //If you want the input at the place of DVD, with the space removed
        list.add(title);
