java - Two way communication between a GUI and a Server Client -
i'm trying send string when button pressed in gui. client class running keep taking string commands command line , send them server processed , response returned.
how can send data through gui , move results gui?
e.g. have button called "pickup" which, when clicked send string "pickup" server, through client class.
likewise, response server either "success" or "fail" printed through thread "serverresponse" in client class , needs somehow sent arbitrary method in playergui class parameter.
thanks help, sorry not using conventional class/method/field naming styles!

you probaly should read , ask questions: tutorial
