    Object_DTO object_DTO = null;

    if(request.getParameter("parameter").equals("hello")) {
        object_DTO = new Object_DTO(); // here null object initialized to a new object
        object_DTO.setAttr("attr");
        ...
    } else if (request.getParameter("parameter").equals("goodbye")) {
        object_DTO = new Object_DTO();
