30% (of the total assessment for KXO151)
Via MyLO
NOTE: All assignments will be checked for plagiarism by a specialist Java program that checks your assignment against other student’s assignments as well as the Internet (including help sites). For more information see: www.ics.heacademy.ac.uk/resources/assessment/plagiarism/demo_jplag.html
Group: 2 students in each group. Students are free to choose who they join with. A group sign-up sheet is available on the KXO151 MyLO site.
NOTE: Students who have not signed into a group by Friday, 17 May, 2019, will be assigned into a group without consultation.
NOTE: Each contributing student within the group will receive the same mark, however, active participation and equal contribution is required from each member of the group. Students who are found to have not participated and / or equally contributed to the assignment work will not be included in the group’s mark. If there is an issue with a student not participating and / or contributing to your group, please contact your lecturer.
The School requires that a group cover sheet listing the members of your group be submitted with your assignment.
Cover Sheet:
The Programming Task
Beware – the version that you implement must match the specifications given below and use the resources provided (even if you prefer some other variant of the task). Other implementations will score poorly.
The code you are to write is to complete a simulation of finding a celebrity (such as a movie star) and convincing him/her to fall in love with you!
You will search the streets of Los Angeles (of USA) for your favourite celebrity. When you find them you’ll try to convince them to fall in love with you. Obviously, you’ll do this by shouting at them from a distance. If you do so three times, then you will convince them and you will go off together happily ever after. If, however, you encounter one of their security guards then you will be dazed for two moves — run into the security detail while you’re dazed and the game is also over. You can shout while dazed but you will stay dazed; you must move twice to clear your head. But dazed or not, you can only erroneously call out to your beloved three times — if you shout in the wrong direction three times, you are arrested for disturbing the peace and placed in an asylum. Game over.
If you are not dazed then it is possible for you to have some idea of your location, the streets around you, and the location of your celebrity (because the noise the paparazzi is making gives their location away).

The completed implementation will consist of three (3) files, only one of which must be written by you. These files are:
• Asst3.java – This is the driver program (with a main() method). The code of this is complete and it MUST NOT be changed. The code in this file is very simple — it declares and instantiates an object of the CelebStalker class and calls its play() method.
• CelebrityBot.java – This is a library class and this file contains resources that you are to use in developing your implementation of the task. The code is complete and MUST NOT be changed.
• CelebStalker.java – This is an organiser class and is the file that you are to write. There is a “skeleton” version of the code – use this as the starting point for your program.
o There will be no main() method in the class, it will contain methods that organise the task. This will include all the interactions with the user.
o You should make sure that you do the following:
▪ Create and use object(s) of the CelebrityBot class. You will LOSE
MARKS if you write code in CelebStalker.java that duplicates
things that could be done using methods of the CelebrityBot class.
▪ Use the trace() method (provided in the skeleton) to include
tracing messages in your program – switch the messages off before
submission.
▪ Use separate methods to implement the separate tasks within the
game.
▪ Use instance variables to store data that is used or changed by more
than one method.
▪ Use local variables to store the data that is used by just one method.
Details on Writing Code in CelebStalker.java
Write code in CelebStalker.java to do the following:
• “Housekeeping” tasks — — CelebStalker()
o Instantiate the CelebrityBot and Scanner classes.
o Switch on the debugging/tracing messages in the CelebStalker and
CelebrityBot classes. (Switch them off before you submit your program
for assessment.)
• Introduction — explain()
o Provide the user with a general explanation of the game.
• Play the game — after entering the gender of their desired celebrity the game is
started with a celebrity chosen at random, the user is prompted to make “moves” until the game is over.
o The game will end when any one of the following happens:
▪ The user tries to move to the street occupied by the celebrity when
they are dazed.
▪ The user shouts their love to empty streets three times.
▪ The user shouts their love to the celebrity three times.
▪ The user chooses to quit the game.

KXO151 – AIEN-SOU – Assignment 3 – 2019
o Before each move the user is provided with information. If they are dazed then they are only told the name of the celebrity with whom they’re in love, otherwise they are told:
▪ The celebrity’s name and the player’s current location (street number) in the Los Angeles road system.
▪ The numbers of the four connecting streets.
▪ The number of times they have declared their love successfully and
unsuccessfully.
▪ Any available information about the location of the celebrity — i.e.
whether the paparazzi has been detected.
o The user is asked what they want to do for this turn. The options are:
▪ Walk into another street (by number).
▪ The player will be asked to enter the number of the street they
want to walk into.
▪ If the street is not connected to their current location they will
not be able to walk, and should be told so.
▪ Otherwise if the street is connected to their current location,
they will enter the new street and, if the new street doesn’t contain the celebrity the game will continue (with the player becoming slightly less dazed if they were dazed); if the new street does contain the celebrity and the player was already dazed then the game is over, otherwise they become dazed and the celebrity flees.
▪ Shout into another street (by number).
▪ The player will be asked to enter the number of the street they
want to shout into.
▪ If the street is not connected to their current location, they will
be told this.
▪ If the street is connected and contains the celebrity then it is
noted that they have declared their love and the game continues. When this occurs three times, the celebrity is seduced and the game ends.
▪ If the street is connected but doesn’t contain the celebrity then it is noted that they’ve disturbed the peace and the game continues. When this occurs three times, the player is arrested and the game ends.
▪ Reset the Game. If this option is chosen then many game parameters are reset:
▪ a new celebrity (of the same gender) is chosen.
▪ the player’s position is changed.
▪ the celebrity’s position is altered.
▪ the player’s head is cleared (i.e. they are not dazed)
▪ the shouting tallies are reset to 0.
▪ Quit the game. The game will end.
• Before playing, the user is asked whether or not they want to play, if not, there is no
game played.
• After each game is over, the user is asked whether they want to play again.
• The numbers of the streets that the user enters should also be remembered (to a maximum
of 20 moves and then the most recent 20 should be remembered). These values (in Page 3 of 7

chronological order) should be displayed at the end of the game. See sample output for more information.
A sample output of the assignment is enclosed within this assignment information package. Use it as a guide to develop your version of the game.
Planning
The first thing that you need to do is to understand what uses can be made of objects of the
CelebrityBot class. To do this:
• Read the code carefully, making sure that you can identify o instance variables
o methods – read the header comments and the code of these and work out what they do.
• Write a driver program to instantiate an object of the CelebrityBot class and call its methods (to check that they behave the way that you think they do).
• Plan how to write code to “organise” the “CelebStalker” activity (using object(s) of the CelebrityBot class)
o Work out the subtasks that will be needed (each of these should be implemented as a method).
o Work out the data that will need to be “shared” by more than one method. These will usually be implemented with instance variables.
o For each method work out:
▪ the data it will need to have passed in (parameters) ▪ the data it will need to pass out (return value)
▪ the algorithm for doing the subtask
• Implement each step after you have planned it – a little bit at a time – compile and test the implementation as you go.
Documentation
Your program files should be fully documented, at least to the same standard as demonstrated in the textbook. This includes in-code comments, descriptions, and where appropriate, explanations for each new constructor, method and variable. Documentation also includes the layout of the Java code and the data printed out to the screen, which should both be in a clear and professional format.
Important Notes:
PLEASE NOTE: This assignment is to be completed by students in groups of 2. If you need help, please look at the textbook or ask your lecturer. Students who have been working through the tutorial exercises should have no 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. Be aware 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 assignment.
• Changing a few variable names, adding different data and / or adding your name to the top of someone else’s code does not make it your own work. See the section on ‘Plagiarism’ below.

• Before you submit your assignment through the KXO151 MyLO website, it is suggested that you make sure the final version of your Java program file compiles and runs as expected – do not change the names of the java file – submit it exactly as you last compiled and ran it. PROGRAMS THAT DO NOT COMPILE AND / OR RUN WILL FAIL THE ASSIGNMENT. If in doubt, you can click on the submitted files, download them from MyLO, and check that they are the files you think they should be.
• Only one complete submission is required from each group. •
Program Style
Your 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
• file name
• your name (in pinyin)
• student UTas id number
• 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
task.
• There should not be a comment stating what every (or nearly every) line of the code does – as in:
num1 = num1 + 1; // add 1 to num1

Submitting Your Assignment
Only one complete submission is required from each group.
You need to submit your assignment package containing the following 3 files to the unit MyLO site:
Asst3.java, CelebrityBot.java, CelebStalker.java
Follow these steps to create a package for your assignment files and then submit your package file:
3. Copy your 3 assignment files into the new folder;
1. Ensure that you add the names and the UTAS ID numbers of both students of your group into the
2. On your computer desktop, create a new folder using your name and UTAS ID number. For
example, if your name is Jianwen CHEN and your UTAS ID number is 111222, then the new folder
must be named Chen_Jianwen_111222;
4. Compress the new folder and name it as a RAR file (or ZIP file). For example, Jianwen CHEN could
name it as Chen_Jianwen_111222.rar.
