Chatting Between Peers

This is a Peer to Peer Application that runs on a Network.

1

In this part, you are required to write Peer-to-peer Application Chatting Java UDP Socket Programming:

• Write a GUI application by using Java.
• Your program should have Text boxes, Buttons, Text Areas, Drop-Downs etc.
• You should enter Source and destination IP addresses, port numbers.
• Also, you should display sent and received messages.
• Blocking Code is Not Accepted.

Extra Requirements:

• Add the timestamp for each exchanged message (for both sent and received)
• Use RED color for sent messages
• Use GREEN color for received messages
• Add button to delete selected message or delete all conversation from both sides.
• Replicate the same task by using TCP Socket instead of UDP Socket.

In this part you are required to apply TCP Java Socket programming, but we will add Two Parts:

2.1

A TCP Client to the Application described in 1.

• This Client requires the additions of buttons to register to the TCP Server Described in 2.2.
• The Server will simply keep a list of UDP clients involved in the Chatting.
• The TCP Server will send a message to each TCP client in the Active Chatting Client described in 1 to inform it of the List of Active Clients. This is similar to Skype and other chatting Servers.
• The server just keeps a list of those that Active Chatting Clients. So, you will need to modify the code in 1 to accommodate this Requirement. The Actual chatting will remain peer-to-peer. But the User chooses which Client to talk to from the List Provided by the Server.
• The login in the Clients is used for Registration to the TCP server to keep track of online Clients. You Should display the List of Active Client.

2.2

Add a TCP Server that keeps track of the Active Chatting Clients as described in 2.1. It should Show a GUI with the Active List of Clients. The login in the Clients is used for Registration.

Extra Requirements:

• Enable sent to all option

• Add the name for each online user next to its corresponding IP and port number i.e. Ali 192.168.1.25 600

• Add file at the TCP server side, which contains the credential for users, login information as username and password as follows:

• Username	Password
  Ali	1234
  Saly	A20B
  Aws	ABcd
  Adam	1Cb2

• Both username and password must be valid for login process, if OK, then the client can proceed and a notification can appear as (Logged in successful), else, a message will appear (invalid login information, either username or password)

• enable the logout button.

• Use different test color for each user.

• Consider the username and passwords are not case sensitive. i.e. Ali = ali = aLi = …
