server-client; client sends a username to the server.

[lkcz]

I have reformed my server code, but the only thing that I am not sure about is how the server would get a selected name from the client?
would I just have to create a protocol and states for the accounts?

say the person was new and types name in to use from the client, how could I get the client to send the name to the server?

state 1
check if the name exists
if true go to state 3 and log in

state 2 create account..

by using bufferedreader and writer, but is there another more efficient way?

The client would connect to the server and send the name to the server.
How does the client connect to the server?
Do you have a protocol for client-server communications? Are you sending Strings or using DataStreams or ?

Why don't you look at how the communication take place between server-client.
