Question 1 Consider the following incomplete UML class diagram. Widget Film title: QString - length: int director String - release Date: Date + Film + Filmit: astring, len: int, dir. QString, rd: GDate) + setTitle(t QString) + setLength(len: int) + setDirector(dir: QString) + setRelease(rd: Date) + getTitleX String + getLength: int getDirector: String + getRelease(): QDate + obtainFilmData() + SaveFilm[f: Film) The Film class takes on too much responsibility. 1. obtainFilmData(), which is used to get user input on film details (title, length, director and release date) via a Graphical User Interface (GUI), and 2. saveFilmi), which is used to save the state of a Film instance to a file. 2 2 COS3711/Assignment 1/2022 Redesign the Film class so that the functionality currently included in it can be achieved using three different classes. 1. The Film class to represent a film with the necessary functions (as given in the above UML class diagram). 2. A FilmWriter class which saves the state of a Film instance (values of the data members of that instance) to a file (you may save it in any sensible format that is human-readable). 3. A Graphical User Interface (GUI) class Filminput, which allows users to enter film information to create Film instances as well as to save Film instances to file (using the Filmwriter). Note: You can decide when Film instance(s) should be saved. Question 2 Make necessary changes in the Film class so that you can access the data members of Film instances using ometaObject. Rewrite the Filmwriter class so that the state of a Film instance is accessed using the generated Metaob ect.
