RMIT Classification: Trusted

COSC1073 Programming 1, Semester 1 2022

Week 10 Assessment

Create two classes: Vehicle and UnmannedVehicle. The class UnmannedVehicle is a

subclass that extends the class Vehicle.

You are also required to write the driver class VehicleInformation, which allows you to

test your implementation of Vehicle and UnmannedVehicle.

The following are implementation details for the classes you need to implement (provided

when not self-evident):

? Vehicle class

o Private fields

§ String vehicleName

§ String vehicleManufacturer

§ int yearBuilt

§ int cost

o Public class constant field

§ int MINYEARBUILT equals to 1886 (as modern cars were invented in

1886)

o getter and setter methods depending on your program design

o void printInfo() method: Print out the information of the Vehicle, including its

name, manufacturer, year built, and cost. An example of the output of this

method is as follows:

Year built: 2021

Cost: 38000

Note: As shown in the above example output, starting from the second line,

each line has three spaces at the beginning.

? UnmannedVehicle class

o Extends the Vehicle class.

o Additional private fields: int SAE and int rating

§ SAE (level of automation) is between 0 and 5 and the rating between 0

and 10.

o Public class constant fields for min and max SAE and, min and max rating

o getter and setter methods depending on your program design

o Overrides the void printInfo() method of the superclass. The method not only

print out the information of name, manufacturer, year built, and cost, but also

print out the information about SAE and rating. An example of the output this

method is as follows.

Vehicle Information:

Name: Model Z

RMIT Classification: Trusted

Manufacturer: Tesla

Year built: 2022

Cost: 88000

SAE: 3

Rating: 7

Your VehicleInformation.java would use Vehicle and UnmannedVehicle classes.

To do that, it has two methods Vehicle buildVehicle() and UnmannedVehicle

buildUnmannedVehicle() that validates the information before calling the

Vehicle/UnmannedVehicle constructor. Information to validate are builtYear, cost, SAE and

rating. These methods will return the object reference if successful, null otherwise.

Your main method should demonstrate the (tentative) creation of 2 unmanned and 2 regular

vehicles.

Below is the sample output.

Sample Output

Error: invalid yearBuilt. Object not created!

Vehicle Information:

Name: RAV4

Manufacturer: Toyota

Year built: 2021

Cost: 38000

Error: invalid sae. Object not created!

Vehicle Information:

Name: Model S

Manufacturer: Tesla

Year built: 2022

Cost: 80000

SAE: 2

Rating: 3

Another Sample Output

Vehicle Information:

Name: ZS

Manufacturer: MG

Year built: 2018

Cost: 35000

Vehicle Information:

Name: RAV4

Marking Guide

Zero marks if the java program cannot be compiled or is not JAVA8

compliant.

0 / 10

Correctly implemented method printInfo() 1 mark

Implementation of the UnmannedVehicle class [2 marks]

Correctly declare the class, including the constructor 1 mark

Correctly implemented method printInfo() 1 mark

The main method, including printing the result in correct format [4 marks]

Objects are correctly constructed, methods are properly called 1 mark

Check invalid instance variable values 2 mark

Info are correctly printed 1 mark

Coding style: [2 marks]

Page 4 of 5

RMIT Classification: Trusted

No duplicate codes (segments with overlap of >≈ 3 lines) 0.5 mark

Proper use of whitespace, including indentation 0.5 mark

Proper use of comments 0.5 mark

Proper names of methods and variables 0.5 mark

Total (50% mark deduction if the program crashes during a normal run) [-5 marks]

Late penalty: 10% per day, up to 5 days [*0.9-0.5]

Submission Instructions

Export the project as an archive; the file name should be the same as the project name, for

example s1234567_Week9.zip and submit the zip file to Canvas under Assignments.

To export a project as a zip file in IntelliJ, click File -> Export -> Project to zip file.

Academic Integrity and Plagiarism (Standard RMIT Warning)

Your code will be automatically checked for similarity against other submissions so please

make sure your submitted project is entirely your own work.

Academic integrity is about honest presentation of your academic work. It means

acknowledging the work of others while developing your own insights, knowledge, and ideas.

You should take extreme care that you have:

? Acknowledged words, data, diagrams, models, frameworks and / or ideas of others

you have quoted (i.e., directly copied), summarised, paraphrased, discussed, or

mentioned in your assessment through the appropriate referencing methods.

? Provided a reference list of the publication details so your reader can locate the source

if necessary. This includes material taken from internet sites.

If you do not acknowledge the sources of your material, you may be accused of plagiarism

because you have passed off the work and ideas of another person without appropriate

referencing, as if they were your own.

RMIT University treats plagiarism as a very serious offence constituting misconduct.

Plagiarism covers a variety of inappropriate behaviours, including:

? Failure to properly document a source.

? Copyright material from the internet or databases.

? Collusion between students.

For further information on our policies and procedures, please refer to the University website.

Assessment Declaration

When you submit your project electronically, you agree to the RMIT Assessment Declaration.
