Write the following two programs

1) TCServer (ThreadedChatServer):

ü Accept TCP connections from any number of TCClient (described next).

ü For each TCClient C it creates a separate thread to serve C and sends a list L of currently connected TCClients to C.

ü If it receives a message M starting with ? from C it sends L to C otherwise it sends M to all currently connected clients.

Usage Syntax:

TCServer <port>

Example:

% TCServer 10123

2) TCClient (ThreadedChatClient):

ü The client connects to the ChatServerThread at <port>

ü The client creates two threads:

§ One thread reads messages from the stdin and sends it to the TCServer.

§ The other thread reads the received messages from the TCServer and displays it to the stdout.

Usage Syntax:

TCClient <server host> <port>

Example:

% TCClient localhost 10123
