I'm trying to send a certain string when a button is pressed in my GUI. My Client class is currently running to keep taking string commands from the command line and send them to the server where they will be processed and a response will be returned.
How can I now send the data through my GUI and move the results back to my GUI?
E.g. I have a button called "pickup" which, when clicked will send the string "PICKUP" to the server, through the Client class.
Likewise, the response from the server would be either "SUCCESS" or "FAIL" which would be printed through the Thread "serverResponse" in my Client class and this needs to somehow be sent to an arbitrary method in the playerGUI class as a parameter.
Thanks for any help, sorry for not using the conventional class/method/field naming styles!

This is the Client class, the thread is where I want to send the response to the GUI class to process and display a specific output. The asterisks is where I want to send the text from button presses in the GUI class (there are other buttons I have deleted the code for easier reading!).
