Working Language
You can choose either Java or Python to complete assignment 1. The higher mark between your Java solution and Python solution will be counted into your final grade. However, you are only credited with one of your solutions, either Java or Python, not both of them or the mixture.
The specification is illustrated based on Java. You can simply translate the Java syntax to Python for your Python solution. Detailed explanations about Python criteria will be posted on the FAQ page on ED.
Specification
The Supermarket Membership Management Department will consist of two main components for Membership Management System (MMS), an administrative component, and an MMS component.
The administrative section will allow, through text-based menus, the login and logout of administrators, the addition and removal of members in the system, the display of membership records, the display of a certain member with name, and the update of member’s accounts.
The MMS component will store a list of all the membership information of the members and a list of the summary of the membership. The MMS component will also allow the creation and display of the collective tuition report as MMS record log. Finally, the MMS component will also handle the display of a certain member information.
Each membership record will include the member’s ID, name, email, phone, address, type, credits, deduction rate, gas deduction rate, dollar available, pay per credits and supermarket fields.
Each supermarket record will include the membership’s name, credit, gas deduction rate, dollar available, deduction rate, pay per credit, and type.
The User Interface and sample I/O will be posted on the Assignment page on ED for a detailed description.
An aside
While reading the first part of the specification, you will notice there is a lot going on.
• How many functions did you identify?
• How many classes did you identify?
• What are the fields in each class?
• How many goals did you identify?
• How many patterns did you think of that might be applicable?
This assignment will be challenging, and you will probably want to manage your time well.
• How long do you think it will take you to code the functions?
• How long do you think it will take you to code each goal?
• A good rule of thumb is to think of an estimate, and then multiply that number by 3 or 4!
• Which parts can you start now?
• Which parts can you start in week 6?
If you complete parts in the same week that you learn the topics (while they are fresh in your mind), they will take less time to complete.
Requirements
• To help visualize the design, a partial class diagram has been provided
• Classes – your design will consist of these 8 classes:
1. Session
2. Supermarket
3. Supermarkets
4. Membership
5. Memberships
6. Slip
7. MMS
8. MMSLog
9. Utils (this is the class to facilitate format and simple I/O, do not change)
• Fields – All the fields have been clarified in each class and they should not be modified. The fields also have some additional requirements and structures:
Lists all have the abstract type of List<>, but must be instantiated with a concrete type that
• Constructors – the constructors of the class have the following requirements:
1. The main method of the program will be in the Session class.
2. All constructors initialize the fields of their classes.
3. The Session, Supermarkets, Memberships, and MMSLog constructors take no parameters.
4. The Supermarket constructor takes three parameters, the name, email, and password, corresponding to the three fields identically named. Other fields require no parameters but the constructor methods.
5. The slip constructor takes membership as the parameter to initialize the fields identically named.
6. The MMS constructor takes supermarket and memberships as the parameters.
7. The Membership constructor requires the following formula to set the value of the fields: Type: set by expense
payPerCredit: set by Type
totalCredit: payPerCredit * expense deductionRate:
set by Type
GasdeductionRate: set by Type
DollarAvailable: totalCredit / 200
expense type payPerCredit deductionRate GasdeductionRate

expense >= 5000 Platinum 4 0.25 0.3
*When updating the expense for a member, the input value will be added to the existing expense of the member. When the value is positive, the expense is accumulated to the membership. Otherwise, the expense is mitigated to the membership.
8. Supermarkets has the following data for Login:
John Smith [email protected] user222
Jane Tyler [email protected] super123
9. Memberships has the following data.

• Utils Class – the Class defines the following formatting:
1. Membership Format:
MembershipHeader( )defines the output format of the header:
+———————-+—————————+————+————+
| Membership Name | Email | Phone | Type |
+———————-+—————————+————+————+
System.out.format(Utils.membershipFormat,name,email,phone,type) will produce a string of the form: name,email,phone,type
e.g.
| Alice Stefan | Add [email protected] coder| 88881111 | Bronze | Note: “| %-20s | %-25s | %-10s | %-10s |%n” defines the space for the string.
2. MMS Format:
slipHeader( ) defines the output format of the MMS header:
+—————–+—————+—————+—————+———-+
| Membership Name | Expense | Credit | Dollars | Type |
+—————–+—————+—————+—————+———-+
System.out.format(Utils.mmsFormat,name,expense,totalCredits,DollarAva ilable,type)will produce a string of the form: name,expense,credit,dollars,type
e.g| Lucy Lu | 158.40 | 3168.00 | 15
| Bronze |
Note: ” | %-18s | %-12.2f | %-18.2f | %-16d | %-14.2f | %-14d | %-10s |%n ” defines the space for the string.
3. Sum Format: System.out.format(Utils.sumFormat,”title”,value)will produce a string of
the form:
Title, value e.g.
Note: ” | %-18s | %-9.2f |%n ” defines the space for the string.
4. Log Format:
UTS CRICOS PROVIDER CODE 00099F
logHeader( ) defines the output format of the MMS header:
| Total credits |
122667.20 |
+————–+—————-+
| MMS Record | RecordID | +————–+—————-+
System.out.format(Utils.logFormat,MMSRecord,name)will produce a string of the form:
MMSRecord,name
e.g.
| MMS 1 | Jane Tyler1 |
Note: “| %-12s | %-9s |%n” defines the space for the string.
Advanced Requirements
To achieve a mark of >84, you must implement the record archive function and retrieve function (or set of functions). This corresponds to 2 options in the MMS menu. Choosing archive option should create a
mmsLog named after the supermarket and the version number. If the new archive is the same as the previous archive, the previous archive will be overwritten with the new version number. In this way, the system avoids archiving the same record with different names. Choosing retrieve option should prompt the user for a valid record name and display the mmsLog matching the name. If the system does not archive
the report with the name, system will show “No MMS is recorded as: <name>”.
Detailed specification please refers to the User Interface and sample I/O page on ED.
Expected Workload
The time to do the assignment to a credit/distinction level has been estimated at
35 hours for a student of average ability who has completed all the tutorial
and lab exercises.
Online Support
If anything about the specification is unclear or inconsistent, check the FAQ first, then contact the subject coordinator who will try to make it clearer by replying to you directly and posting the common questions and answers to the FAQ. This is similar to working on the job, where you ask your client if you are unsure what has to be done, but then you write all the code to do the task.
The preferred way to ask assignment related questions is to participate in the lectures, lab activities, UPASS, and consultation sessions. Students are expected to seek help through the following steps:
Step 1: Check the FAQ
Step 4: Forward to the subject coordinator
ED Marking
Your solution is marked for correctness by comparing the output of your system to the output of the benchmark system in ED. You can submit a solution to ED many times by press “MARK”; I urge you to do this, so you receive credit for your work. Any code hasn’t been “MARK” by ED won’t be credited.
Your code is marked by software, so there are chances to get a good mark by fooling or
specification about design rules and spoofy check refe rs
to the document “Spoofy Check”.
