Algorithm Design and Analysis

Milestone 1: Software Assignment

Due 9 October

Submission Instructions

Create a single .zip archive containing the following components:

? For development tasks 1–3, please include .java files in the correct folder

format. Please ensure code files do not contain any non-English characters

(such as comments in Chinese) because my AUT computer cannot display

these characters. Worse, these code files do not compile for me.

? For development task 4, please create a short 2-4 minute video of the

demonstration in .mp4 format. Please ensure that the video file size is not

more than 30MB.

Please submit the .zip file on Blackboard→Assessment→Milestone 1.

Development tasks

The purpose of this assignment is to develop a client/server messaging system

where clients can connect to the server and use it to send messages to specified

clients.

The system should include the following components:

1. Server which maintains a list of clients that are currently connected (each

with a unique name) and passes messages from one client to another. It

should provide some mechanism for notifying clients when the server will

be terminating connections or when a client disconnects. It should also

demonstrate at least one design pattern. (15 marks)

2. Client Interface which is a GUI used to connect to the server and obtain

a list of other currently connected clients. It should enable a client to

send a text message to another chosen client via the server and display

the messages received from other clients. The list should update the GUI

whenever a new client connects to or disconnects from the server.

(15 marks)

3. Two Other Features such as user accounts, sending and receiving images,

utilising UDP for some communication, hidden connections via a password

whose presence is only known to the other hidden clients, or when the

server starts it sends e-mails to a list of addresses notifying them of the

IP address and port of the server. (15 marks)

4. Demonstration of features of the complete system using a screen-cast

video. The video should comment on the requirements listed in tasks

1–3 above. (5 marks)
