Question

Need help with coding in Java. Just create the server.

In this part, you will implement a Server class that will accept only one connection, process its requests, and then the Server will end.

Create a Server class in the package edu.ucdenver.server
The constructor should take the port and backlog to open the server.
The server should implement the Runnable interface.
Override the following public methods:
- public void run()
  - This will implement your server. Similar to runServer() from our lecture examples.
  - Upon a client connection, the server will listen for requests. Once one is received, will be processed (see below) and the response will be send to the server.
  - Keep accepting requests until the client disconnect. No termination message will be send, the client will just disconnect.
Protocol:
- the communication will be text based.
- fields will be delimited by a vertical bar ( | )
- clients may send either two requests:
  1. "E|text" -> requesting the server to encode the clean text "text" into Morse Code
  2. "D|morse" -> requesting the server to decode the received text "morse" from Morse Code to clean text
- Server may respond:
  - "0|text" -> to either E and D requests. Text will correspond with either the encoded or decoded string.
  - "1|Not Implemented" -> if the server got a requests unrecognized by the server. E.g. "C|" or "E Hello world"
  - "2|Invalid Message Format" -> if the message format is not correct. Eg. "E", the command is correct but the arguments received are not (in this case no text was sent).
Important Notes:
- Quotes were added just to delimit the message descriptions, and are not part of the actual message.
- Make sure your server terminates after the client disconnects. Your code test will be aborted otherwise.
