1 CSC8406 2019/2020: Object Oriented Programming Module Coursework (resit) Aims Improve knowledge and experience of applying Object Oriented Design and Implementation techniques to solving problems using the JAVA programming language, specifically with the aim of gaining experience in the following: • Programs, programming and programming environments. • Object-oriented programming: comments; types; variable declarations; arithmetic and Boolean expressions; assignment. • Loops and conditions; input and output. • Data structures: arrays and lists. • Simple algorithms: searching, sorting. • Methods. • Objects; inheritance; applications. Assessment (Deadline: 16:00, Friday, 19 June 2020) This coursework is marked out of a total of 100. You are required to submit the following: • Part 1 Source Code (75%): The main emphasis is on proficiency in Object Oriented Programming using Java, including: definition of classes (fields, constructors, methods), inheritance, exception handling, as well as appropriate use of APIs such as collections. One of the classes of your application should include a static method called main containing the evidence that you tested your program. • Part 2 Testing (5%): The main emphasis is on the appropriate choices for test cases. • Part 3 Documentation (20%): This includes appropriate Java Docs, and a well- structured project report (PDF, or Word document). The project report should include your reasoning behind your design (include also a class diagram). The project report should describe implementation details, and include a discussion of test cases. The project report should also include instructions on how to run your program. Plagiarism The University has strict policies for penalising plagiarism, and all work submitted for assessment must be your own work. This does not prohibit discussion among students about coursework. Indeed, such discussion to increase understanding is positively encouraged. However, the answers submitted must be your original contribution, written and designed by you. It is permissible to include some material drawn directly from other sources (if you think this benefits the report part of the submission), but such non-original material must be explicitly declared to be a quotation from an external source, and that source must be listed. 2 Scenario: Music Library This scenario is associated with the implementation of a program that stores information about recorded music collections, like Apple’s iTunes except that it does not have to actually play the songs themselves. • Music artists are either soloists or bands. Soloists just have a name, but bands also have a list of members, who may be soloists in their own right. • A music track has information about the track title, artist, date, the length (in time) of the track, the track rating (an integer), the location of the music file (MP3) and the size of the music file. A music track may also include a guest artist. • A music album has an artist, a title and an ordered list of tracks. • Music library programs often store the number of times a track has been played. Problem: Basic I • Define a Java class to store information about artists, including their name and membership to bands if appropriate. • Define a Java class to store information about music tracks. Include methods to: o create a track; o set and get the title, artist, date, length, rating, location and size of the track; o add a guest artist to the track; o get a list of all individuals on the track, including band members and guest artists; o add to the play count of a track; o get the play count of a track. Problem: Basic II • Define a Java class to represent albums. Provide methods to: o create an album; o set and get the name and type of the album and the artist; o define the list of tracks for the album; o get the overall running time of the album; o get the overall file size of the album; o get the average rating of tracks on the album. Problem: Basic III • Define a Java class to represent a music library. Provide methods to: o create a library; o add tracks and/or albums to the library; o create a list of tracks from the library with the lowest rating. 3 Problem: Extensions I Define a special type of album, the compilation album. These albums may or may not have an artist, or may have a number of different artists. Each track on a compilation album should also store the original album that the track came from. For example, Bohemian Rhapsody by Queen was originally on the album A Night at the Opera and subsequently appeared on the compilation album Greatest Hits Vol I, part of the Queen Greatest Hits series. Problem: Extensions II Write a method for a library that works out how to back up all of the music tracks onto a small number of discs. Different types of disc (CD, DVD) have different capacities in terms of total file size, so the capacity of the disc should be a parameter to the method. This is an example of the general problem known as bin-packing problem. Submission Submit all your files including documentation and source code within a properly structured zip folder. Submission must be done electronically through NESS. Deadline: 16:00 on Friday 19 June 2020
