Question

Project Description

Complete the Film Database program described below.

This program allows users to store a list of their favorite films. To build this program, you will need to create two classes which are used in the program’s main function. The “Film” class will store information about a single movie or TV series. The “FilmCollection” class will store a set of films, and includes functions which allow the user to add films to the list and view its contents.

IMPORTANT: Remember that every class must be defined in a separate .java file, and the name of the file must match the name of the class exactly.

Film class:

This class is a simple container for information about one film. The class should contain the following public variables:

1. A string for the “title” of the film

2. A string for the film’s “description”

3. An integer “rating”

The Film class requires only one function definition: the constructor function. The constructor function should take a String “newTitle” as a parameter, used to initialize the “title” variable similar to the examples given above.

FilmCollection class:

The Film Collection class stores a set of Film objects. The class should define the following private variables:

1. An array of Film objects named “films”

2. An integer “totalFilms”

The constructor function for the FilmCollection class requires one parameter: an integer “maxFilms”, indicating the number of films the class is allowed to store. Initialize the “films” array in the constructor function, using the “maxFilms” parameter to set the size of the array.

Two other functions must be defined for the program to run:

1. void addFilm(Film f) This function should store the Film object “f” in the “films” array.

2. void printFilms() This function should print the title of each film in the “films” array.

Answer 1

thanks for the question, here are the 3 java classes - Film.java, FilmCollection.java and FilmDriver.java (main class)

======================================================================================

public class Film {

    private String title;
    private String description;
    private int rating;

    public Film(String title) {
        this.title = title;
        description = "";
        rating = 0;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public int getRating() {
        return rating;
    }

    public void setRating(int rating) {
        this.rating = rating;
    }

    @Override
    public String toString() {
        return getTitle()+" "+getDescription()+" ";
