How to control the printwriter from a separate method : Im working on building my own GUI program that talks to my pc from a tablet. I have the server side done in java but my problem is on the client side. 

I want to send data out the PrintWriter to the server from a separate method. 
I have accomplished sending in the code below (it sends 'a') but i cant figure out how to send it from a separate method. i believe its a basic java scope problem that im not understanding. i would really appreciate the help.


I have tried moving the variables into other scopes.

import java.io.*;
import java.net.*;

public class TestClient {

	public static void main(String[] args) {
        String hostName = "192.168.0.3";
        int portNumber = 6666;

        try (	//Connect to server on chosen port.
        		Socket connectedSocket = new Socket(hostName, portNumber);
        		//Create a printWriter so send data to server.
                PrintWriter dataOut = new PrintWriter(connectedSocket.getOutputStream(), true);
        		
                BufferedReader stdIn = new BufferedReader(new InputStreamReader(System.in))
            )
        {
        	//Send data to server.
        	dataOut.println("a");
        	
        }catch (UnknownHostException e) {
            System.err.println("Don't know about host " + hostName);
            System.exit(1);
        } catch (IOException e) {
            System.err.println("Couldn't get I/O for the connection to " +
                hostName);
            System.exit(1);
        } 
    }
	
	public static void sendToServer() {
		//I want to control the print writer from this method.
		//I have failed i all the ways i have tried.

	}
}
