CSC72002 Object Oriented Programming - Assignment 2

Weight: 40% of your final mark

Due: 30 September 2020, 11:00 pm

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

(https://docs.oracle.com/javase/8/javafx/api/javafx/scene/image/ImageView.html)

? 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 red

? Demonstrate the use of the Timeline class to change the colour of the second shape every 2

seconds indefinitely, e.g. red to blue to red to blue to red 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 Sculptures for a

small exhibition (see the attached class at the end of this assignment). Your app will allow the user

(exhibition’s staff) to enter data about a sculpture. When the user is finished, the data will be written

to a Sculpture object, and then the Sculpture object will be added to a LinkedList. The user can then

enter data for a new sculpture and repeat the process.

2 | P a g e

Your app will need the following UI controls that will be mapped to instance variables in the

Sculpture class provided at the end of this document:

? Text field for the sculpture title

? Text field for the sculpture artist

? Slider for the year created (sculpture creation year, e.g. 2020)

? Radio buttons for the sculpture height (tall (over 5m), medium (shorter than 5m, taller than

1m) and short (under 1m))

? A combo box for sculpture’s weight (Very Heavy, Heavy, Medium, Light, Very Light, etc.)

? A list view for the following four countries of origin of sculptures:

o Italy

o France

o China

o United Kingdom

? CheckBoxes for the material(s) that the sculpture might have (e.g. Stone, Metal, Glass,

Pottery, Wood Carving, Other, etc.)

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

? Write the data from the UI to a Sculpture object (use the attached class at the end of this

assignment)

? Add the Sculpture object to a LinkedList that will store all sculptures entered by the user

? Reset the UI controls so the user can enter a new sculpture

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

? A “New Sculpture” button that resets the UI controls

? An “Add Sculpture” button that creates a new instance of the sculpture, sets the Sculptures

instance variables (via the mutator methods) using the values from the UI controls and then

adds the sculpture to the LinkedList

PLEASE NOTE:

? You CANNOT modify the attached Sculpture 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 sculpture titles (Donatello’s Equestrian

Monument of Gattamelata, The Terracotta Army, Michelangelo’s David, Maman) 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 sculpture artist is

printed to the console

2 | P a g e

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 the 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 four (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 by the due date. Please leave enough time for it

to upload, so do not submit at the last minute!

Book Class

Use the following class for your Sculpture in Part 3:

public class Sculpture {

// text field

private String title;

// text field

private String artist;

// slider

private Integer yearCreated;

// radio field

private String height;

// combo box

private String weight;

// list view

private HashSet<String> countryOfOrigin = new HashSet();

// check boxes

private HashSet<String> material = new HashSet();

public Sculpture() {

}

public String getTitle() {

return title;

}

public void setTitle(String title) {

this.title = title;

}

public String getArtist() {

return artist;

}

public void setArtist(String artist) {

this.artist = artist;

}

public Integer getYearCreated() {

return yearCreated;

}

public void setYearCreated(Integer yearCreated) {

this.yearCreated = yearCreated;

}

public String getHeight() {

return height;

}

public void setHeight(String height) {

this.height = height;

}

2 | P a g e

public String getWeight() {

return weight;

}

public void setWeight(String weight) {

this.weight = weight;

}

public HashSet<String> getCountryOfOrigin() {

return countryOfOrigin;

}

public void setCountryOfOrigin (HashSet<String> countryOfOrigin) {

this.countryOfOrigin = countryOfOrigin;

}

public HashSet<String> getMaterial () {

return material;

}

public void setMaterial (HashSet<String> material) {

this.material = material;

}

}
