Assessment Scenario/Problem-

Java program for a Music Social Network system.

You can work on this coursework either alone or in a pair with a colleague, not necessarily from the same seminar or lab group.

You are to implement two servers (Social Network and Chat) and several client objects. You must produce a graphical user interface for the client and server systems.

The functionality of the Client is that it should be able to:

• connect to the server and register its IP address as a valid user along with the name of the user and his/her profile in order to join the social network service (i.e. login).
• remove the user from the service (i.e. when disconnecting to execute log-off command).
• send a message to the server for selecting the desired person P with whom to ask fora new friendship.
• receive friendship acceptance notifications.
• receive and show post from friends.
• play music shared by friends.
• search for people with a particular profile (e.g. they like "opera").
• send/receive text from other clients.
• send/receive file/images from other clients.

The required functionality of the Social Network Server is that it should be able to:-

• keep a record (in some form) of all on-line members, their IP addresses, their profiles, and their shared songs.
• accept new member registrations and add them to the active participants list.
• accept requests from the members to remove itself from its records (log-off ).
• list the roster of current registered members and send it to new clients.
• receive post messages and perform the actions required such as sending the right information to the members.
• handle multiple member connections concurrently.

The required functionality of the Chat Server is that it should be able to:-

• accept new requests for starting new chat sessions.
• receive messages from members and perform the actions required such as sending the message to the receiver members.
• handle multiple members connections concurrently.

The mark awarded will be proportionate to the functionality implemented - you can pick and choose which functionality you want to implement. The design of the system is up to you. Demonstration and explanation of the prototype is required. Please also refer to the marking scheme defined separately in the Java Coursework Marking Scheme file.

As well as demonstrating your Server and Client you must submit a short report to include:-

1. List of the students presenting this particular implementation.

2. Commented listings of the client and server 

3. An explanation of the design of your system which details items such as:

• the nature of the network connection used. That is if the server holds an open connection to each client or not and if connections are pooled or created on the fly.
• the data structure used by the server to record active participant information
• how the client handles the communication with the Social Network server.
• how the client handles the communication with the Chat server.
• any other enhancements you have made for extra points - you will get additional marks for every feature even if the feature is part of a higher band marking requirements and you have not fulfilled some of the lower bands marking requirements.
