日期：2018-05-21 01:18

Introduction

This assignment is due by 11pm Friday of Week 12 (25 May, 2018).

This assignment is worth 25% of the marks for your final assessment in this unit. Heavy penalties

will apply for late submission. This is an individual assignment and must be your own work.

Please note the section on plagiarism in this document.

In preparing your assignment please note the following:

o The assignment must be done using the BlueJ environment.

o The Java source code for the assignment must be implemented according to the

FIT9131 Java Coding Standards.

o You must acknowledge all code in your assignment that you have taken from

other sources.

Any points needing clarification may be discussed with your tutor in the lab classes. You should

not make any assumptions about the program without consulting your tutor.

Specification

For this assignment you will simulate the playing of a Football World Cup. This is a simplification

of the actual FIFA World Cup but the simulation you will develop requires no prior knowledge of

the rules of football. This section specifies the required functionality of the program.

Only a text interface is to be used for this program, there is to be no GUI. More marks will be

gained for a game that is easy to follow with clear information/error messages.

System description

The Football World Cup is played between 4 teams. The teams are ranked from 1 to 4, with 1

indicating the highest ranking and 4 the lowest.

The Cup is played in two stages: Preliminary and Final.

During the Preliminary stage, each team plays the other three teams resulting in a total of six (6)

games played. The games during the Preliminary stage occur sequentially and the result of each

game is shown on the screen as it is completed. In the Preliminary stage a team gains 3 points for a

win, 1 point for a draw, and 0 points for a loss.

At the end of the Preliminary stage the system will display a summary of the results with the

teams sorted from first to last, based on the following criteria:

FIT9131 Semester 1 2018 Assignment 2

• The teams will be listed from most to least points.

• If teams have the same points, then the team with the higher number of goals scored will

be placed higher on the table.

• If teams cannot be separated by any of the previous criteria, then the higher placing in the

table will be determined randomly.

After the Preliminary stage is completed, the top two teams play in the Final. The only difference

between the final and the preliminary games is that the final must have a winner, the Football

World Cup Champions!

At the end of the Final the overall results are displayed on the screen, including the name of the

Football World Cup champion team, the Golden Boot Award player, and the Fair Play Award

team.

Class Design

Your design should have at least the following three classes: Player. Team and Game. A better

solution will have more classes, including for example, Menu and RandomGoalsGenerator. For

each class you should have a default constructor and a constructor that accepts values for the fields

as parameters.

Each class should also have appropriate accessor and mutator methods and be able to return its

state in the form of a String. Validation of values for fields should also be implemented. You

should not allow an object of a class to be set to an invalid state.

Player

An object of Player will have at least the following fields:

name – of type String. The name can contain only alphabetical characters and at most one

hyphen, ‘-‘, to accommodate names that may be hyphenated such as Zeta-Jones. There must be a

minimum of two alphabetic characters in the name, it should be of a sensible maximum length,

and it cannot begin or end with a hyphen. The two players in a team cannot have the same name.

goals – of type int representing the number of goals scored. This will be used to determine the

‘Golden Boot’ award for the top goal scorer.

Team

An object of Team will have at least the following fields:

name – of type String and is the name of the country the team is representing.

ranking – of type int. This field refers to the team’s relative strength compared to the other teams

in the Cup. No two teams can have the same ranking. The ranking must be between 1 and 4

inclusive (as there will only be four teams in the competition).

2 players – of type Player. Each team will have two players who are the goal scorers.

Each team will also have a yellow card and red card score. A yellow card is shown to players who

have committed serious fouls, while a red card is shown to players who have committed more

severe offences and they are sent from the field. The cards are associated with a team, not an

individual player. The showing of yellow and red cards is determined randomly, both are rare and

some games have no cards shown at all. But there are usually four times as many yellow cards

shown as red cards. The total yellow and red card marks will determine a team’s Fair Play score,

which will be used to determine the Cup’s Fair Play Award. Each yellow card is worth one mark,

each red card is worth two marks. The lower the total marks, the fairer the team.

In addition to the fields mentioned above, an object of class Team must be able to store and/or

return other information about its performance in the Cup. You must decide on which of the

following should therefore be fields and which do not have to be fields: the number of games the

team has played in the Cup, the number of games won, lost, drawn, number of goals scored, and

overall points.

Game

The Game class will have at least one field, an ArrayList of Team objects. The Game class also

has at least three methods: playGame(), playPenaltyShootOut(), and displayGameResult().

The playGame() method simulates the playing of a game between two teams. This is done by

randomly generating the number of goals scored by each team. The number of goals generated

should be in a specified range. The team with the highest ranking will have a greater chance of

winning. This will be simulated by giving the higher ranked team a wider range of possible goals

as follows:

• Higher ranked team: a goal range of 0 to (5 + a random upset (a random number

between 0 and 2))

• Lower ranked team: a goal range of 0 to ((5 – difference in team rank) + a random

upset (a random number between 0 and 2))

The goals will be randomly distributed between the two players.

The playPenaltyShootOut() method simulates the playing of a penalty shoot-out, if required for a

Final that ends in a draw. One player of each team has five shots at goal. The team whose player

has the highest number of goals at the end of the five shots wins. If the score is equal then each

player has another shot at goal. This continues until there is a result. The goals scored by a player

in a penalty shoot-out are not counted towards the Golden Boot Award.

The displayGameResult() method displays on the screen the result of the game at the end of the

game, for example:

Game result: Spain 4 vs. Australia 0

Cards awarded: Australia - 1 red card.

The team records (played, won, etc.) are updated after a game is completed.

System Interface

When the program starts, the system reads the details of each team from file called ‘teams.txt’.

The details include each team’s name and ranking. Once the information is loaded from the file

there is no more reading or writing to the file during the actual running of the program.

The program then prompts the user for the names of two players in each team who will be the goal

scorers. If the name entered is invalid then the user is prompted to re-enter. If the name re-entered

is invalid then a default value is allocated, e.g. player-1-Ghana

The system will then offer the user the following menu options and you must display a text based

menu that uses the Scanner class to obtain input from the keyboard:

A. Play Preliminary Stage

B. Play Final

C. Display Teams

D. Display Players

E. Display Cup Result

X. Close

If the user chooses option ‘A’ the Preliminary stage will be played.

If the user chooses option ‘B’ the Final will be played between the top teams from the preliminary

stage, as previously described. If option ‘B’ is chosen but the Preliminary stage has not been

played an error message will be displayed. If the final ends in a draw then a penalty shoot-out is

played.

If the user chooses option ‘C’ the record of each team is displayed. For example:

Played Won Lost Drawn Goals Points Fair Play Score

Australia 6 4 2 0 14 12 3

China 6 3 2 1 10 10 0

Ghana 6 3 2 1 9 10 0

Spain 6 2 4 0 6 6 4

If the user chooses option ‘D’ the players are listed with their number of goals scored. The list

does not need to be sorted in any order. For example:

Cahill (Australia) - 8

Rogic (Australia) - 6

Gao (China) - 7

Yu (China) - 3

………..

……….

If the user chooses option ‘E’ the name of the Football World Cup champion team, the Golden

Boot Award player, and the Fair Play Award team will be displayed to screen. For example:

Football World Cup Winner: Australia

Golden Boot Award: Ronaldo from Spain

Fair Play Award: Ghana and China

Note that there can be multiple players that win the Golden Boot Award and there can be multiple

teams that win the Fair Play Award.

After menu item A to E, the menu is re-displayed on the screen.

If the user chooses option ‘X’, the system should write the same information shown when option

‘E’ is chosen to a file called ‘statistics.txt’. The system will then close.

Important Notes

1. Your program must demonstrate your understanding of the object-oriented concepts and

general programming constructs presented in FIT9131. Consider carefully your choice of

classes and how they interact. You must use appropriate data structures to store the

various objects (player, team, etc.) in the program. Make sure that you discuss your design

with your tutor. You must document any additional assumptions you made.

2. You will be required to justify your design and the choice of any data structures used at

the interview.

3. Validation of values for fields and local variables should be implemented where

appropriate. You should not allow an object of a class to be set to an invalid state (i.e. put

some simple validations in your mutator methods).

4. Your program should handle incorrect or invalid input and present the user with relevant

error messages. No invalid input should crash the program.

5. Exception handling should be used where appropriate.

Assessment

Assessment for this assignment will be done via an interview with your tutor. The marks will be

allocated as follows:

• 10% - Test strategy for the Player class.

• 35% - Java code and object-oriented design quality. This will be assessed on appropriate

implementation of classes, fields, constructors, methods and validation of the object’s

state.

• 55% - Program functionality in accordance to the requirements.

You must submit your work by the submission deadline on the due date (a late penalty of 20% per

day, inclusive of weekends, of the possible marks will apply - up to a maximum of 100%). There

will be no extensions - so start working on it early.

Marks will be deducted for untidy/incomplete submissions, and non-conformances to the FIT9131

Java Coding Standards.

All submitted source code must compile. Any submission that does not compile, as submitted, will

receive a grade of ‘N’.

Interview

You will be asked to demonstrate your program at an “interview” following the submission date.

At the interview, you will be asked to explain your code/design, modify your code, and discuss

your design decisions and alternatives. Marks will not be awarded for any section of

code/design/functionality that you cannot explain satisfactorily (the marker may also delete

excessive in-code comments before you are asked to explain that code).

In other words, you will be assessed on your understanding of the code, and not on the actual code

itself.

For on-campus students, interview times will be arranged in the tutorial labs in Week 12. It is

your responsibility to attend the lab and arrange an interview time with your tutor. Any student

who does not attend an interview will receive a mark of 0 for the assignment. The actual

interviews will take place in Week 14.

For off-campus learning (OCL) students, the interviews will be organised during week 12 and

will take place online via Skype or other video facility during Week 14. It is your responsibility to

make yourself available for an interview time. Any student who does not attend an interview

will receive a mark of 0 for the assignment.

Submission Requirements

The assignment must be uploaded to the FIT9131 Moodle website by the due date.

The submission requirements for Assignment 2 are as follows:

A .zip file uploaded to the FIT9131 website containing the following components:

• the BlueJ project you created to implement your assignment.

• a document in MS Word format containing your Test Strategy for the Player class. Note

the JUnit facility in BlueJ is NOT to be used for this assignment.

• a completed Assignment Cover Sheet. This will be available for download from the

unit’s Moodle site before the submission deadline. You simply complete the editable

sections of the document, save it, and include it in your .zip file for submission.

The .zip file should be named with your Student ID Number. For example, if your id is 12345678,

then the file should be named 12345678_A2.zip. Do not name your zip file with any other name.

It is your responsibility to check that your ZIP file contains all the correct files, and is not

corrupted, before you submit it. If you tutor cannot open your zip file, or if it does not contain the

correct files, you will not be assessed.

Marks will be deducted for any of these requirements that are not complied with.

Warning: there will be no extensions to the due date. Any late submission will incur the 20% per

day penalty. It is strongly suggested that you submit the assignment well before the deadline, in

case there are some unexpected complications on the day (e.g. interruptions to your home internet

connection).

Plagiarism

Cheating and plagiarism are viewed as serious offences. In cases where cheating has been

confirmed, students have been severely penalised, from losing all marks for an assignment, to

facing disciplinary action at the Faculty level. Monash has several policies in relation to these

offences and it is your responsibility to acquaint yourself with these.
