Design Draft Due: 6:00PM, Wednesday (in Week 9), 01 May 2019 Prototype Demo: 6:00PM, Wednesday (in Week 10), 08 May 2019
Completed Assignment Due: 6:00PM, Wednesday (in Week 12), 22 May 2019 GENERAL DESCRIPTION
This INDIVIDUAL software development assignment consists of THREE PARTS, and is worth 22% of the assessment of this course. In this individual assignment, you will develop Java software for electronic donator records management.
1. PART ONE (2 Marks): submit a design draft of the assignment in week 9. Your tutor will provide you feedback and inputs to further improve your software design and development. Your design draft should describe:
all the classes needed and their responsibilities, the fields and methods of each class,
the relationship of the classes.
2. PART TWO (2 Marks): demonstrate a prototype of your software using lab computers. At this stage, you must demonstrate that:
your code can be compiled via command line,
your programs are able to read from and write to files,
your programs could update and delete records,
your software is able to manipulate simple inputs, and to produce appropriate outputs accordingly.
3. PART THREE (18 Marks) is the completion of the software development assignment.
SOFTWARE DESCRIPTION
In this individual assignment, you will design and develop a Java software package to process the donator information records in different suburbs according to the given instructions/commands.
Your Java software MUST
Read and validate the contents of TWO input text files (i.e. record file and instruction file), and Process the donator information records in the record file according to the instructions in the
instruction file. The instructions should be performed sequentially (i.e. one after the other).
When your program ends, your software saves the resulting records list (after being processed) to TWO output files (that are the result file containing the processed donator records list and the
report file containing the query results).
DESCRIPTION AND FORMAT OF INPUT DONATOR RECORDS
When your DM system starts up, it will firstly read in valid donator records in the input records file; and then process the valid donator records according to the instructions in the instructions file.
1. The input donator record file contains zero or multiple donator records in the predefined format:
Separators: blank line(s) are used to separate the records.
Invalid fields: fields with error(s). Invalid fields should be ignored and not read into the system. Invalid records: records missing any compulsory field or with invalid compulsory field. Invalid
records will be discarded and will not be read and processed by your DM system.

2. An input donator record consists of seven possible fields to specify necessary information of a donator and his/her recipients. There are two compulsory fields, i.e., name, birthday; and the rest five fields are optional.
1) name (compulsory): donators name, in the form of a string of forename(s) and surname, all along one line. A name cannot include numeric and punctuation characters.
2) birthday (compulsory): donators birthday, in the format of dd-mm-yyyy. Example: 11-07- 2014.
3) address: is a string that may span more than one line and should end with the abbreviation of a state in Australia (for example NSW, VIC).
4) postcode: in the form of 4 numeric digits.
5) phone: in the form of a sequence of 8 numeric digits. Leading zeros cannot be ignored.
6) recipient: types of recipient, for instance, the disabled, animal protection organization,
environment protection organization, etc. Different types of recipients helped by the same
donator are spaned in the same line while separated by comma(s).
7) donation: amount of money donated to a corresponding recipient. There is a one-to-one
relationship between the recipient and the donation.
3. Format
Compulsory fields are required for all records when they are read in from the input records file. That is, you may have a donator record with name and birthday, or another record with all seven fields.
Each field begins on a new line and starts with the field name.
Single/Multiple white spaces are used to separate field name and the field value/content.
Fields may occur in any order.
If the number of recipient and donation is mismatched, you may discard the unmatched recipient(s)
or donation(s) at the end of the field.
Example: donatorsample1.txt is a sample donator record file, with records as below:
name
birthday
phone
recipient
donation
address
postcode
name
birthday
address

DESCRIPTION AND FORMAT OF INPUT INSTRUCTIONS
Your software needs to read in and parse the valid instructions in instructions file and process the valid
records with valid instructions.
1. The instructions file contains zero or multiple instructions:
There are four possible instructions: update, donate, delete, and query.
Each instruction occurs on a new line.
Each instruction begins with one of the instructions followed by a list of parameters.
2. Description of instructions
2
COMP9103 Software Development in Java Assignment Semester1, 2019
Update a persons basic information (not include recipient and donation field) o For instance, the instruction
update name Jo Bloggs; birthday 08-07-1998; phone 88884444; postcode 2008; address 9001 Chester Crescent, Chatswood, NSW;
is supposed to add a record to your list for a donator with name Jo Bloggs, birthday 08-07- 1998, phone number 88884444, postcode 2008, address 9001 Chester Crescent, Chatswood, NSW. Note the use of a semicolon (;) to separate the fields in the instruction.
o Your system will check whether this is an existing record:
o ifthedonatorsnameandbirthdayareidenticaltothoseofanexistingrecord,theexisted
record will be updated by the new information. E.g., update or merge the fields with the
given values;
o otherwise a new valid record needs to be automatically created and added to your list by
your system.
Donate money to a corresponding recipient(s) using the donators name and birthday o For instance, the instruction
donate Sam Brown; 11-09-1990; the disabled, 200; animal protection org, 300;
indicates donation of $200 and $300 to recipients the disabled and animal protection org respectively by Sam Brown (birthday 11-09-1990). The amount of donation for each recipient should be added if the recipient(s) was/were already existed in the donors record, otherwise recipient and donation fields should be initialized with the given information. Ignore the instruction if there is no such donator in your system.
Delete a donator from your system using the donators name and birthday o For instance, the instruction
delete Jeff Vader; 29-04-1987
indicates: deleting the record with name Jeff Vader and birthday 29-04-1987.
QuerythestatisticsusingthefollowinginstructionsandsavethequeryresultstoreportFile.Query results from different queries should be separated using dash lines ().
(1) Query the records by name and save all the query results to the report file. The format of the query instruction is listed as below:
o query name David Joans
Note: Sort the donators in ascending order by their birthdays if there are multiple donators that have the same name.
(2) Query top n donators and save query results to reportFile. o query top n
indicates: query top n donators by total amount of donation and save the query results to reportFile. If there are multiple donators that have the same amount of donations, sort the donators in ascending order by their names. For example:
query top 3 Jeff Vader; 29-04-1987; 5000 Jo Bloggs; 08-07-1998; 5000 Sam Brown; 11-09-1990; 2000
Note: you are required to implement a sorting method instead of invoking a Java sort API. 3
COMP9103 Software Development in Java Assignment Semester1, 2019 (3) Query the statistics of recipients and save the query results to reportFile. The format is:
o query recipients
indicates: for each type of recipients in the system, query the suburb(s) where the largest amount of donation (from related donators) was received. For instance, if there are three types of recipients in the system e.g. the disabled, animal protection organization, environment protection organization, the results as below should be appended to reportFile:
query recipients-
The disabled: 2000; postcode 2050
Animal protection organization: 3000; postcode 2018, 1058 Environment protection organization: 1000; postcode 2000
The above result represents that the disabled collected the largest amount of money ($2000) from all relevant donators in the suburb 2050 and
FORMAT OF OUTPUT FILES
1. Your software needs to save the resulting data collection to the files including results file and report file.
2. The output files should have all the necessary resulting records.
3. Each field should fit on ONE line only.
4. Records should be separated by blank lines.
5. The format of output records should be consistent, e.g. fields are listed in same order and date format are consistent.
6. Report File: the results of different queries should be separated by a dash line with query instruction as shown in previous section.
SOFTWARE EXCUTION
Your software must be executed using command line in the following format:
java DM19S1. DM recordFile instructionFile resultFile reportFile
DM19S1 is the package containing your assignment software.
DM is the name for the main class.
Two input files specified by command line arguments:
o recordfilecontainingthelistofdonatorrecords
o instructionfile containing the set of instructions/operations to be carried out by your
software
Two input files specified by command line arguments:
o resultfile saving the processed donator records
o reportfile saving the results from query commands
DO NOT implement a graphical user interface (GUI). DO NOT hard code the path/name of the
input/output files as they will change between runs of the program. Some example invocations using the Command Prompt:
java DM19S1.DM u:recordsrec01.txt u:ins01.txt w:outres01.txt W:report01.txt
java DM19S1.DM c:rec03.txt d:ins07.txt result.txt report.txt
