Assignment 2 Specification Semester 2, 2014 Page 2 of 9
Part A – Code Comprehension
A Sample program is provided that creates a list of shapes
stored in an array. This program uses classes:
Shapes, Square, Rectangle and ShapesList. The main method is
in the class: TestingShapesListClass.
Conduct a careful examination of this code. Make sure you
understand this code as it will help you with your
own programming for this assignment. Using the uncommented
sample code for classes: Shapes, Square,
Rectangle and ShapesList provided, answer the following
questions:
1.

21. Draw a UML diagram of each of the Shapes, Rectangle and Squ
are classes using the code that has been
provided. Complete this using the examples that have been pro
vide in the lecture slides.
2.
Draw a UML diagram of the ShapesList class using the code tha
t has been provided. Complete this using the
examples that have been provide in the lecture slides.
3.
Add appropriate comments into the file: ShapesList.java to expl
ain all the methods. At a mimimum, explain the
purpose of each method. For the more complex methods reading
input from a file, sorting the data and
exporting data to the file, insert comments to explain the code.
4.
Explain in what the purpose of the call to hasNextLine() in read
FromFile() in ShapesList.java.
5.
Briefly explain the code in bubbleSort() in the ShapesList class.
What attribute are the shapes being sorted by?
Name the sort algorithm that is being used. Explain in words ho
w it works, using an example. Why do we need
to use two for loops?
6.
Briefly name and describe one other sorting algorithm that coul

22. d have been used.
7.
Explain the use of the return value in the getArea() method in th
e Rectangle class. What is it returning? Where
does the value come from?
8.
Examine the lines to open the output file and write the outputStr
ing in the ShapesList class:
File file = new File(“export.txt”);
System.out.println(file.getAbsolutePath());
output = new BufferedWriter(new FileWriter(file));
output.write(outputString);
Where is the output file located? Find BufferedWriter in the Ja
va API documentation and describe the use of
this object.
9.
Examine the code in the exportToFile method. What is the pur
pose of the ‘rn’ in the toString() method that is
used to produce the output string?
10.
Briefly explain why a try and catch clause has been included in
the code to read from the file. Remove this from
the code and remove the input file and take note of the error. R
e‐add the line and investigate what happens if
the input file is not present.

23. Part B – Development of a basic Class
Your first coding task is to implement and test a class that
represents a Vehicle. A Vehicle object has a make
a model, a registration number, vinnumber and year of
manufacture.
To complete this task, you are required to:
1. Create a new package in eclipse named
assignTwoStudentNNNNN where NNNNN is your student
number. You will author a number of classes for this assignment
and they will all be in this package.
CRICOS Provider No. 00103D ITECH 1000 Programming 1
Assignment 2 Specification Semester 2, 2014 Page 3 of 9
2. Use the UML diagram provided to implement the class
Vehicle in a file called Vehicle.java. Starter code
has been provided with this assignment, copy this starter code
into your Vehicle.java file. Complete the
constructors that will create a Vehicle object.
3.
Author all mutator and accessor (set and get) methods and the to
String() as indicated in the UML diagram.
4.
Ensure that your Vehicle class includes the following validation
within the mutator (set) methods:
a.

24. The make of the Vehicle cannot be null nor an empty String (ie
“”). If an attempt is made to set the
name to an invalid value the method should return false.
b.
The year of manufacture of the Vehicle must be greater than or
equal to 1950. If an attempt is made to
set the value of the year of manufacture to an invalid value the
method should return false and not
change the value of the yearOfManufacture.

- String model;
- String registration;

+ toString():String
Figure 1: UML Diagram for the class Vehicle
Part C – Development of extended Classes using inheritance
Your second coding task is to implement and test a class that
represents a Car. For this assignment a Car is
a vehicle with additional attributes such as number of seats,
number of doors, whether it is a hatchback or
not, whether or not it has tinted windows and whether it has
manual transmission or automatic transition. A
Car isA Vehicle. The Car class will extend a Vehicle class, so
the make, model, registration, vin number and
CRICOS Provider No. 00103D ITECH 1000 Programming 1

26. Assignment 2 Specification Semester 2, 2014 Page 4 of 9
year of manufacture will be inherited from the Vehicle class.
After you have created the Car class, you are
asked to create a similar class for another type of vehicle that
you choose (e.g. Truck, Caravan, Boat,
Tractor….).
To complete this task you are required to:
1.
Use the UML diagram provided to implement the class Car in a
file called Car.java. Ensure that you adhere to
the naming used below as this class will be used by other classe
s that you will develop. Starter code is provided
for you to copy.
2. Make sure that your Car class extends the Vehicle class.
3.
Ensure that your class includes the following validation within t
he mutator (set) methods:
a.
numSeats cannot be less than two. If an attempt is made to set t
he numSeats to an invalid amount,
then the method should set the numSeats to two and return false
, otherwise set the numSeats as given
and return true.

27. b.
The numDoors cannot be less than two. If an attempt is made to
set the value of the numDoors to an
invalid value the method should return false.
4.
Write additional methods for toString() and a method to check e
quality with another car (equality should be
based on vinNumber being the same for both vehicles).
5.
Select two Cars that you will create. Choose values for each of t
he data attributes for each car. Write a class
called TestClass (starter code is provided to copy from) and wit
hin the main method write code that will :
a.
Instantiate an instance of the Car class for one of the Cars you s
elected using the Car() constructor
b.
Sets all of the instance variables to the appropriate values using
the mutator methods (set)
c.
Change the yearOfManufacture to increase the yearOfManufactu
re of the first Car by 5 years.
d.
Instantiates an instance of the Class Car for a second different C
ar contained in the table below using

28. the Car(make:String, model:String, registration: String, vinNum
ber: String, yearOfManufacture: int,
numSeats:int, numDoors: int, hatch: boolean, tintedWindows: b
oolean,manual: boolean) constructor
e.
Display both of the Cars that you have created using the toStrin
g() method
f.
Display both of the Cars that you have created using individual
accessor (get) methods in a print
statement

Now create a second class representing another vehicle (e.g. bik
e, trailer, caravan, truck, or tractor etc.) in a
similar fashion to the way you created the car class. (The car cla
ss is similar to the square class in the sample
code provided. The square class extends the Shapes class. The R
ectangle class also extends the Shapes class.
Your second vehicle type is similar to the Rectangle class. Your
vehicle e.g. truck will extend the Vehicle class.)
a.
Decide on your vehicle type and then choose attributes particul
ar to that vehicle that will be instance
variables
b. Draw a UML class diagram for your new class
c.
Create your new class in a new file named appropriately e.g. Tr
actor.java
d. Make sure your new class extends the Vehicle class
e. Write get and set methods for your new class
f. Write a toString() method for your new class
g.
Test your new class by writing code to create an object based on
this class in your TestClass class
h.
Test your object by modifying one of the instance variables usin
g a set method then display the object

Part D – Development of the Garage class
Using the UML diagrams provided and the information below
you are required to implement and test classes
that represent a Garage object. For this assignment a Garage
contains multiple vehicles up to a specified
capacity. (This may be modeled on the ShapesList class in the
sample code. The ShapesList class contains
multiple Shapes in an array. Your Garage will in a similar way
contain multiple Vehicles in an array.)
Garage.java
Garage
- name: String
- Vehicles: Vehicle[]
- numVehicles: int
- capacity: int
~ Garage (initName: String, capacity: int) <<create>>
+ getName():String
+ getNumVehicles():int
+ setName(newName: String): boolean
+ addVehicle(newVehicle: Vehicle): Boolean
+ sortVehicles()

32. + exportToFile() //itech5000 students only
+ readFromFile() //itech5000 students only
+ toString():String
Figure 3: UML Diagram for the class Garage
1.
You have been provided with starting point in Garage.java Writ
e get and set methods as well as an addVehicle
method.
2.
Create a method for sorting the Vehicles in the Garage (model t
his on the ShapesList bubblesort method)
3. Update the class TestClass adding in code to:
a. Create an instance of the Garage class
b.
Add at least two Cars created to the Garage class using the add
Vehicle() method
c.
Add at least two other vehicles (e.g. Tractor or Bike) to the Gar
age class
d.
Display the details of the garage that you have created using the
toString() method in the Garage class –
these should be accessed via the instance of the garage class tha
t you have created

33. e.
Display all of the vehicles in the garage by looping through and
accessing each vehicle in turn. Each
vehicle should be accessed via the instance of the Garage class
you have created, then printed using the
toString() method on that vehicle.
(Hint: Look at the TestingShapesListClass.java class for exampl
es of similar code to the code you will need in your
TestClass. In TestingShapesListClass, Shapes are added to a Sh
apesList object. In your code Vehicles are added to the
Garage object).

Part D – Using the Classes
Create a new class called GarageSystem.java . This class is to
be used to implement a basic menu system.
You may find some of the code you have already written in the
TestClass.java can be copied and used with
some modification here. You may also find the menu code from
assignment one helpful as an example of
using a switch statement to process the menu options. Each
menu item should be enacted by choosing the
appropriate method on the Garage object. The menu should
include the following options:

34. 1. Populate the Garage
2. Display Vehicles in Garage
3. Sort Vehicles data
4. Import data (ITECH5000 students only)
5. Export data (ITECH5000 students only
6. Exit
– this option will allow the user to enter
data for each vehicle OR you may write
a populate method that will insert data hardcoded in your
method directly into each vehicle. You will
use the set methods on your Car object and the set methods on
your additional vehicle (Hint: copy
this code from your TestClass.)
– display the data of all vehicles in the garage,
using your toString() method on the
Garage object.
sort the vehicles into alphabetical order
based on name. (Hint: look at the sort method in the ShapesList
class. It sorts on area of the shape,
you need to sort based on name of the vehicle.)
For students enrolled in ITECH5000 ONLY:
– this menu should read in data from the filed
called SampleData.txt. You are required
to add the additional data described above to this file.

35. – save the data to a new file ExportData.txt
