Deadline for Submission: 9PM (Shanghai) Wednesday, Week 8, 16 April 2025

Maximum Marks Available: 15 (15% of the total assessment for KXO151)Submission:

Via MyLONOTE: All assignments will be checked for plagiarism by a specialist Java program that checksyour assignment against other student’s assignments as well as the Internet (including help

sites).

ssignment Type: ndividual

Requirements:

PLEASE NOTE: This assignment is to be completed by Students individually. If you need help, pleaselook at the textbook or ask your lecturer. Students who have been working through the tutoriaexercises should not have much difficulty in completing this assignment.

PLEASE NOTE: The submitted Java code must be able to be compiled from the command line using

Javac the Java programming language compiler command, or from a basic editor such as jGrasp. Baware that development programs such as Eclipse often use features only available when run using

their system, meaning that their code may not run on a system without their development program.

Programs that do not run from the command line using javac (to compile) and java (to run) because

of a missing development program feature will fail the assignmentYou are required to perform the following tasks:

Write a Java application program named Asst2.java which provides the user with theirpersonalised ' number. The details (specifications) of this task are given below. Note that thecorrectness marks you receive for your program will depend on how well it matches this

specification. If you decide to implement something that is more elaborate than specified, you shouldunderstand that:

• There will be no marks awarded for the elaborations you have designed and penalties mabe applied for confusing/extraneous code.

• Your program must still meet the basic specifications given below.

The program is to implement a simple personalised number program. The user will be asked four

questions about themselves.

• Their family name (to be stored in a String that may not contain spaces).
• The initial (first letter) of their first given name (to be stored in a char).
• Their year of birth (to be stored in an int variable).
• Whether or not they are female (to be stored in a boolean variable).

The answers to these questions will be used to generate a ' personalised ' number (in the range of 1

to 9) for the user, this will be displayed on the screen. To calculate the ' personalised ' number,

several values will be used:

• An initial ' personalised ' number value of 5.
• A family name factor length of 5.
• Special letters ‘A’, 'S', ‘T’ and'Z'.The user will always see one ' personalised ' number.

NOTE: Part of the assessment of your program may be done automatically, so it is important that you

follow the specification exactly, for example the questions must be asked in the order given and the

method the user is given to indicate that they want to see another fortune must be as specified.

Details

• The user will be asked to enter their family name. (Rules: The entry should not contain

spaces.)

• The user will be asked to enter the first letter of their first name.
• The user will be asked to enter the year of their birth.
• The user will be asked to enter true/false as to whether they are female.
• All the above information should then be displayed to the user in the form (with sample data

of "Clark", "J", 1989, true) of:

J.Clark (male) was born in 1989.

• The program will then work out the user's 'personalised ' number as follows:

o Starting with 5 as an initial number, if the birth year is even then the number will be

9 times (number= initial number*9).

if the birth year is odd then the number will be multiple of 3 times (number= initial

number*3).

o If the user is female, then:

• if the initial of their first name is either of the special letters [A, S, T or Z]

then the number is 5 times (number= initial number*5); otherwise, it is 2

times (number= initial number*2).

o otherwise, for a male user

• if the length of the family name is a multiple of 3 then the number is 6 times

(number= initial number*6); otherwise, it is 4 times (number= initial

number*4).

o Finally, the number is reduced and calculated by summing the digits of the

calculated number until a single-digit number is obtained. If the result is 0, it is set

to 1 to ensure the personalised number remains between 1 and 9.

• The Personalised number is then displayed on the screen.
• After the Personalised number has been displayed, the user is asked whether they want to

see another. To see another personalised number, they must enter the character 'y' or 'Y' (for

yes). They will then be asked for another family name, initial, year, and gender and will see

another personalised number. If they enter any letter other than 'y' or 'Y' the program will

stop.

• The user will be shown a message saying how many personalised numbers were told.

A sample output of the program is attached to the end of this document.

Program Style

The program you write for this assignment must be a single class called Asst2 with the code in a file

called Asst2.java. There should be a single method (the main() method) in this class.

Page 2 of 10Your program should follow the coding conventions introduced in this unit and shown in the

textbook, especially:

• Variable identifiers should start with a lower-case letter
• Final variable identifiers should be written all in upper case and should be declared before

all other variables

• Every if-else statement should have a block of code for both the if part and the else part (if

used)

• Every loop should have a block of code (if used)
• The program should use final variables as much as possible
• The keyword continue should not be used
• The keyword break should only be used as part of a switch statement (if required)
• Opening and closing braces of a block should be aligned
• All code within a block should be aligned and indented 1 tab stop (approximately 4 spaces)

from the braces marking this block

Commenting:

• There should be a block of header comment which includes at least

o file name

o your name (in pinyin)

o student UTas id number

o a statement of the purpose of the program

• Each variable declaration should be commented.
• There should be a comment identifying groups of statements that do various parts of the

Note

The High Distinction grade is reserved for solutions that fully meet the requirements & are highly distinguished from

other assignments by their high-quality work & their attention to detail (usually only 10% of students).

PLEASE NOTE: The assignment will receive a single composite mark. The assignment will be accessed

from the point of view of the requirements: “Does it meet the requirements, and how well does it do

it?” Where there is some inconsistency in that the work does not completely match every sub

criterion within a particular criterion, then the grade reflects the value of the work ‘on average’.

Submission:

Your completed solution (your Asst2.java file, plus a text file containing the output of your

program using your UTas id number as the name of the file, for example, 159900.txt) must be

submitted by the deadline. Assignments must be submitted electronically via KXO151 MyLO website

as files that can be read by a text editor such as Microsoft Notepad (submit the *.java file - not the

*.class file). Follow the following 代写KXO151 Programming & Problem Solving steps to create a package for your assignment files and then submit

your package file:

1. On your computer desktop, create a new folder using your name and UTAS ID number.

For example, if you name is Jianwen Chen and your UTAS ID number is 159900, then the

new folder must be named Jianwen_Chen_159900;

2. Copy your 2 assignment files into the new folder;Page 6 of 10
3. Use the WinRAR application to compress the new folder and name it as *.rar. For

example, Jianwen Chen would name it as Jianwen_Chen_159900.rar.

4. Submit your *.rar file to the unit MyLO “Assessments/Assignments/Assignment 2” folder.
5. If WinRAR application is not available on your computer, try to use a similar application

to compress the new folder and name it as *.zip, and then submit the *.zip file.

Details of the actual submission procedure are available through the MyLO webpages.

Students who believe that this method of submission is unsuitable given their personal

circumstances must make alternative arrangements with their Lecturer prior to the submission date.

Extensions will only be granted under exceptional conditions and must be requested with

adequate notice on the Request for Extension forms. No extension will be provided after due

date.

In submitting your assignment, you are agreeing that you have read the ‘Plagiarism’ section below,

and that your assignment submission complies with the assignment requirement that it is your own

work.Plagiarism

While students are encouraged to discuss the assignments in this unit and to engage in active learning

from each other, it is important that they are also aware of the University’s policy on plagiarism.

Plagiarism is taking and using someone else's thoughts, writings or inventions and representing

them as your own; for example, downloading an essay wholly or in part from the internet, copying

another student’s work or using an author’s words or ideas without citing the source.

Plagiarism is a form of cheating. It is taking and using someone else's thoughts,

writings or inventions and representing them as your own; for example, using an

author's words without putting them in quotation marks and citing the source, using

an author's ideas without proper acknowledgment and citation or copying another

student’s work.

If you have any doubts about how to refer to the work of others in your assignments,

please consult your lecturer or tutor for relevant referencing guidelines, and the

academic integrity resources on the web at: www.academicintegrity.utas.edu.au/.

The intentional copying of someone else’s work as one’s own is a serious offence

punishable by penalties that may range from a fine or deduction/cancellation of marks

and, in the most serious of cases, to exclusion from a unit, a course or the University.

Details of penalties that can be imposed are available in the Ordinance of Student

Discipline – Part 3 Academic Misconduct, see:

www.utas.edu.au/universitycouncil/legislation/

The University reserves the right to submit assignments to plagiarism detection

software, and might then retain a copy of the assignment on its database for the

purpose of future plagiarism checking.

It is important that you understand this statement on plagiarism. Should you require clarification

please see your unit coordinator or lecturer. Useful resources on academic integrity, including what

it is and how to maintain it, are also available at: www.academicintegrity.utas.edu.au/.

Working with others, including generative Generative AI tools (e.g., ChatGPT, Codex, Copilot)

One effective way to grasp principles and concepts is to discuss the issues with your peers or friends

(or even to interact with one of the many generative AI tools available now), and you are encouraged

to do this. We also encourage you to discuss aspects of practical assignments with others. However,

once you have clarified the principles of the question, you must express the expression, algorithm or

program entirely by yourself. In other words, you can discuss the question, but not the solution. Same

applies to advanced Generative AI tools, we do not encourage students solve the assignment using

advance AI tools, however, if you would like to take assistance from these AI tools to help to

understand the question, then you need to provide below detail:

If you get help from an AI tool with a programming task, add this at the top of your source file

or embed the contents (excluding the top and bottom """) into the program-level """ documentation

After the appropriate prompt write a brief summary of:

• what the problem(s) were that you needed help with;
• what assistance the external tool provided (for example, did it identify a problem in syntax,

or an issue with the approach you were using?)

• what you have learned from its suggestion(s) (which will allow you to solve such problems

yourself in future)

If you get help from an AI tool with a task where you produce a document, either upload a

separate Word or PDF containing the same details as above or, within the body of the document, add
