Java sockets - Client doesn't read the strings from server's socket

Question

I have two Java projects that communicate with sockets through strings. One is a client and the other is a server. The server accepts the connection trough the \"ServerSocke

Answer 1

In your send methods, try changing out.write(m) to out.println(m).

Each time you are using the readLine method it will keep reading until it hits a new line character or line separator. The println method will automatically put a line.separator at the end of the string you are trying to send.

Answer 2

Your server sends "USERNAME" and then waits. The client reads the next line, and blocks until it receives it. So you have a deadlock, since the server never sends an EOL character. If the client reads a line, the server should send a line.
