COMP231-Java Project 3 Solved

Specifications
What You Must Implement

You must define a class named MediaRental that implements the MediaRentalInt interface functionality (index A). You must define classes that support the functionality specified by the interface. The following specifications are associated with the project:

1.      Define a class named MediaRental. Feel free to add any instance variables you understand are needed or any private methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).

2.      The media rental system keeps track of customers and media (movies ,music albums and games). A customer has a name, address as string , a plan and two lists. One list represent the media the customer is interested in receiving and the second one represents the media already received (rented) by the customer. There are two plans a customer can have: UNLIMITED and LIMITED. UNLIMITED allows a customer to receive as many media as they want; LIMITED restricts the media to a default value of 2 (this value can be change via a media rental class method).

A movie has a title, a number of copies available and a rating (e.g., "HR"). An album has a title, number of copies available, an artist and the songs that are part of the album. A game has title,number of copies,and the weight (in grams) is also stored.

3.      You must define and use at least four classes (not including MediaRental) as part of your design. At least two of those classes must be in a superclass/subclass relationship (Inheritance Requirement). The other two can be defined as you wish. Feel free to define as many classes as you want. These classes must support the functionality of the system otherwise you will not receive any credit.

4.      One of your classes must define an equals method that has as parameter an Object parameter.

5.      The database for your system needs to be represented using two ArrayList objects. One ArrayList will represent the customers present in the database; the second will represent the media (movies, albums , and games).

6.      Regarding the searchMedia method: the songs parameter represents a substring (fragment) or the full list of songs associated with the album. If the full list is provided you can assume commas will be part of the string. Hint: you may want to consider using the indexOf method of the String class.

7.      Your program should store the results in a file between executions of the program, so that when the program is run again it will start up with the same inventory contents as when it last terminated.

8.      Feel free to use Collections.sort to sort your data.

9.      Write test driver.

10.  Handle expectations where it’s needed.

11.Not all the details associated with the project can be fully specified in this description. The sooner you start working on the project the sooner you will be able to address any doubts you may have.

Index A:

MediaRentalInt interface Includes:

Method Detail addCustomer

void addCustomer(String name,String address,String plan)

Addsthe specifiedcustomer tothedatabase. The addressisaphysical address (note-mail). Theplan optionsavailable are: LIMITED and UNLIMITED. LIMITED defines a default maximum of two media that can be rented. Parameters: name - ,address -,plan -

 

addMovie

void addMovie(String title, int copiesAvailable,String rating)

Adds the specified movie to the database. The possible values for rating are "DR", "HR", "AC".

Parameters:title - ,copiesAvailable -,rating -

 

addGame

void addGame(String title, int copiesAvailable,double weight) Adds the specified game to the database. Parameters:title - ,copiesAvailable -,weight -

 

addAlbum

void addAlbum(String title,int copiesAvailable,String artist,String songs)

Adds the specified album to the database. The songs String includes a list of the title of songs in the album (song titles are separated by commas).

Parameters: title - ,copiesAvailable -,artist -,songs -

 

setLimitedPlanLimit

void setLimitedPlanLimit(int value)

This set the number of media associated with the LIMITED plan.

Parameters: value -

 

getAllCustomersInfo

String getAllCustomersInfo()

Returns information about the customers in the database. The information is presented sorted by customer name. Returns:

 

getAllMediaInfo

String getAllMediaInfo()

Returns information about all the media (movies, albums, and games) that are part of the database. The information is presented sorted by media title. Returns:

 

addToCart

boolean addToCart(String customerName,String mediaTitle)

Adds the specified media title to the cart associated with a customer.

Parameters:customerName - ,mediaTitle -

Returns: false if the mediaTitle is already part of the cart (it will not be added)

 

removeFromCart

boolean removeFromCart(String customerName, String mediaTitle) Removes the specified media title from the customer's cart.

Parameters:customerName - ,mediaTitle -

Returns: false if removal failed for any reason (e.g., customerName not found)

 

processRequests

String processRequests()

Processestherequestscartofeachcustomer.Thecustomers will beprocessedinalphabeticalorder. Foreachcustomer, the requests cart will be checked and media will be added to the rented cart, if the plan associated with the customer allows it, and if there is a copy of the media available. For UNLIMITED plans the media will be added to the rented cart always, as long as there are copies associated with the media available. For LIMITED plans, the number of entries moved from the requests cart to the rented cart will depend on the number of currently rented media, and whether copies associated with the media are available.

For each media that is rented, the following message will be generated:

"Sending [mediaTitle] to [customerName]" Returns:

 

returnMedia

boolean returnMedia(String customerName,String mediaTitle)

This is how a customer returns a rented media. This method will remove the item from the rented cart and adjust any other values that are necessary (e.g., copiesAvailable) Parameters:customerName - ,mediaTitle -

Returns:

 

searchMedia

ArrayList<String> searchMedia(String title,String rating, String artist,String songs)

Returns a SORTED ArrayList with media titles that satisfy the provided parameter values. If null is specified for a parameter, then that parameter should be ignore in the search. Providing null for all parameters will return all media titles.

Parameters: title - ,rating - ,artist -, songs Returns:
