CSC72002 Object Oriented Programming - Assignment 2

Weight: 40% of your final mark

Due: Friday, 13 December 2019, 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 rghanbarPart1.

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 rghanbarPart2.

? 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 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 rghanbarPart3.

For this part of the assignment you need to build an app that stores a collection of cars for a small

car rental company (see attached class at the end of this assignment). Your app will allow the user

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

Car object and then the Car object will be added to a LinkedList. The user can then enter data for

a new car and repeat the process.

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

class provided at the end of this document:

? Text field for the car make

? Text field for the car model

? Slider for the year (car production year e.g. 2019)

? Radio buttons for the transmission type (Automatic and Manual)

? A combo box for car’s body type (SUV, Sedan, Hatch, and Ute)

? A list view for the following four types of insurance coverage provided to the customer:

? Collision Damage Waiver (CDW)

? Supplemental Liability Protection (SLP)

? Personal Accident Insurance (PAI)

? Personal Effects Coverage (PEC)

? Check boxes for some extra options that the car might have (e.g. rear-view camera, GPS

or satellite navigation, extra airbags, extra tinting)

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

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

assignment)

? Add the Car object to a LinkedList that will store all cars entered by the user

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

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

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

? An “Add Car” button that creates a new instance of the car, sets the cars instance variables

(via the mutator methods) using the values from the UI controls and then adds the car to

the LinkedList

PLEASE NOTE:

? You CANNOT modify the attached Car class

Part 4 – Parallel Programming

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

called rghanbarPart4.

Write a program that uses 4 threads to print out 4 car makes (Toyota, Hyundai, Jeep, Audi) in the

console, in parallel, 20 times each make. 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 care make 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 rghanbar_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!

Car Class

Use the following class for your Car in Part 3:

public class Car {

// text field

private String make;

// text field

private String model;

// slider

private Integer year;

// radio buttons

private String transmission;

// combo box

private String bodyType;

// list view

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

// check boxes

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

public Car() {

}

public String getMake() {

return make;

}

public void setMake(String make) {

this.make = make;

}

public String getModel() {

return model;

}

public void setModel(String model) {

this.model = model;

}

public Integer getYear() {

return year;

}

public void setYear(Integer year) {

this.year = year;

}

public String transmission() {

return transmission;

}

public void setTransmission(String transmission) {

this.transmission = transmission;

}

public String getBodyType() {

return bodyType;

}

public void setBodyType(String bodyType) {

this.bodyType = bodyType;

}

public HashSet<String> getInsurance () {

return insurance;

}

6

public void setInsurance (HashSet<String> insurance) {

this.insurance = insurance;

}

public HashSet<String> getExtraOptions () {

return extraOptions;

}

public void setExtraOptions (HashSet<String> extraOptions) {

this.extraOptions = extraOptions;

}

}
