CSC72002 S3 2019 Assignment 2

Weight :40% of your final mark

Specifications

Your task is to complete various exercises in NetBeans, using the Java language, and to submit these via the MySCU link created for this purpose.

Marking criteria includes :

Use of correct coding style, including the use of comments; Accuracy of coding; Use of suitable coding structures; Correct submission and naming conventions of assessment items as required.

Getting Help

This assignment is to be completed individually. It is the opportunity to gain an understanding of the concepts of object oriented programming and coding syntax. It is important that you master these concepts yourself. You are permitted to work from the examples in the study guide or textbook but you must acknowledge assistance from other textbooks or classmates. In particular, you must not use online material or help from others, as this would prevent you from mastering these concepts.

Who can you get help from? Use this diagram to determine from whom you may seek help with your program.

Please Note for all parts of the assignment:

You cannot use the same examples that the Study guide uses. Examples taken from the study guide will result in no marks and may count as plagiarism. Marks will be given for high cohesion. This means that you should not have all your code in the start method. Your program should make use of multiple methods, each with a distinct function.

Part 1 – Shapes and Events

Create a new JavaFX project called usernamePart1 in NetBeans. In my case, the project would be called pdarcyPart1.

Using a GridPane:

Add at least 4 different shapes to your app (Every shape must have at least 1 event) Demonstrate the use of at least 4 different Mouse events Demonstrate the use of at least 2 different Key events Demonstrate the use of at least 1 inner class Demonstrate the use of at least 1 anonymous inner class Demonstrate the use of at least 1 lambda expression Demonstrate the use of setHgap, setVgap, setHalignment and setValignment Ideally you should have a method for each shape

Part 2 – Images and Animations

Create a new JavaFX project called usernamePart2 in Netbeans. In my case, the project would be called pdarcyPart2.

Add an image as the background for your app using an ImageView object Demonstrate the use of at least 3 methods of ImageView e.g. setFitHeight docs.oracle.com Add a Polygon with at least 8 sides Demonstrate the use of the PathTransition class using the polygon as the path and any shape as the node Demonstrate the use of the FadeTransition class to fade the polygon in and out Add a second shape (can be any shape) and set the fill to green Demonstrate the use of the Timeline class to change the colour of the second shape every 1 second indefinitely e.g. green to yellow to green to yellow to green etc.

Part 3 – UI Controls and Collections

Create a new JavaFX project called usernamePart3 in NetBeans. In my case the project would be called pdarcyPart3.

For this part of the assignment you need to build an app that stores a collection of books for a small library (see attached class at the end of this assignment). Your app will allow the user (library’s staff) to enter data about a book. When the user is finished, the data will be written to a Book object and then the Book object will be added to a LinkedList. The user can then enter data for a new book and repeat the process.

Your app will need the following UI controls that will be mapped to instance variables in the Book class provided at the end of this document:

Text field for the book title Text field for the book author Slider for the year published (book publication year e.g. 2019) Radio buttons for the book length (Long +1000 page, medium and short -100 pages) A combo box for book’s cover type (Paperback, Hardcover, Loose-leaf, etc.) A list view for the following four publishers that distribute books: Penguin Random House Hachette Livre HarperCollins Macmillan Publishers Check boxes for the genre(s) that the book might have (e.g. Fantasy, Science Fiction, Western, Romance, etc.)

Once a user has entered the data for a book, your app needs to do the following:

Write the data from the UI to a Book object (use the attached class at the end of this assignment) Add the Book object to a LinkedList that will store all books entered by the user Reset the UI controls so the user can enter a new book

One way to do this would be to have the following (you do not have to do it this way) :

A “New Book” button that resets the UI controls An “Add Book” button that creates a new instance of the book, sets the books instance variables (via the mutator methods) using the values from the UI controls and then adds the book to the LinkedList

PLEASE NOTE:

You CANNOT modify the attached Book class

Part 4 – Parallel Programming

Create a new Java project called usernamePart4 in NetBeans. In my case the project would be called pdarcyPart4.

Write a program that uses 4 threads to print out 4 book authors (Mark Twain, Stephen King, Jane Austen, J. K. Rowling) in the console, in parallel, 20 times each author. NOTE: you will not receive any marks if your program does not use threads.

Use two different ways to create the threads: by using the Thread class, and by using the Runnable interface Set different priority to each thread (maximum, normal, minimum) Write the code to put the threads to sleep for 100 milliseconds each time a book author is printed to the console

Use of thread pools:

Create a fixed thread pool that returns a thread pool with a maximum of 3 threads Write the code to shut down the fixed thread pool after current tasks are complete and return TRUE when shutdown is complete Create a cached thread pool that returns a thread pool that creates new threads as required Write the code to shut down the cached thread pool immediately and return TRUE if all tasks in the cached thread pool have been terminated

Avoiding data corruptions

Assume that there is a possibility of data corruption in this program (data corruption may not happen in this program). Write the necessary code to your methods to allow only one thread can execute the code block at one time so that data corruption is prevented. In order to do so, use both thread Synchronisation and explicit lock object techniques separately.

Submission

You should now have 4 NetBeans projects. You must zip the projects into one zip file called username_A2.zip For example, mine would be pdarcy_A2.zip.Submit this file via the Assignment 2 link on MySCU Please leave enough time for it to upload, so do not submit at the last minute!
