Read about the HTTP protocol.
Look at the HttpURLConnection class and other classes in the java.net package.
Also read up on Sockets.

thank you very much for your help, I did exactly what you told me to do, and I knew how to handel cookies if I have object from URLConnection (client side), but to implement a server side program, I'll need to have server socket to accept connections, I didnt find any useful info on how to read cookies from the server side (to check whether this client visted me befor or not for example).
is there any misunderstanding? or I am seraching for somthing wrong? thanks again!

Did you read about the Request Header sent by a browser to the server? That is where a Cookie would be.
It is up to the server to define and send the cookie using a Response Header SetCookie field.
