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