Please anyone know socket programming using JAVA?

You are required to write a TCP client and server network application to check the validity of a pword written by the user and read by the client process. The client process should prompt the user to enter a pword. The client process should read the pword from the keyboard and sent it through a socket to the server process. The server should read the pword and compare it to a prestored pword. If both are the same, then the server should return, "pword accepted" otherwise, the server should return "Invalid password" Guys help me please
