Single server key-value store (TCP & UDP)

A server program that serves as a key-value store.

It's set up to allow a single client to communicate with it and perform three basic operations:

• PUT(key, value)
• GET(key)
• DELETE(key)

---

Usage (locally):

1. Open up two terminal windows and navigate to /Project1/src
2. In one window, type javac servers/*.java (hit ↩), followed by java servers.Main <Port#> <TCP/UDP>, where <Port#> is the port number the server advertises its service with, and <TCP/UDP> instantiates the type of server that communicates with the TCP or UDP protocol (hit ↩)
3. The server is now running
4. In the other window, type javac clients/*.java (hit ↩), followed by java clients.Main <Hostname> <Port#> <TCP/UDP>, where <Hostname> can be either the server's hostname or IP address, Port# is the port number the server advertises its service with, and <TCP/UDP> instantiates the type of client that communicates with the TCP or UDP protocol (it has to match the server's) (hit ↩)
5. The client is now running
6. The predefined protocol is:
   • PUT:key:value(hit ↩)
   • GET:key(hit ↩)
   • DELETE:key(hit ↩)
7. To shut down the server, type server stop(hit ↩) or server shutdown(hit ↩)
8. To shut down the client, type client stop(hit ↩) or client shutdown(hit ↩)
