Thread: PrintWriter out problem

Hello all,

I seem to be having a problem with printwriter, it sends to the server the first time but then i cannot get it to send anything else (particularly the disconnect function).

import java.net.*;
import java.io.*;
import java.util.*;
 
public class A_Chat_Client implements Runnable{
 
	Socket SOCK;
	Scanner INPUT;
	Scanner SEND = new Scanner(System.in);
	PrintWriter OUT;
 
	public A_Chat_Client(Socket X) {
 
		this.SOCK = X;
 
	}
 
	public void run() {
 
		try {
 
			try {
 
				INPUT = new Scanner(SOCK.getInputStream());
				OUT = new PrintWriter(SOCK.getOutputStream());
				OUT.flush(); 
				CheckStream();
 
			} finally {
 
				SOCK.close();
			}
 
		}catch(Exception e) { e.printStackTrace(); }
	}
 
	public void DISCONNECT() {
 
            try {
 
		SEND("CLOSE"); // <------ this does not send 
		SOCK.close();
		System.exit(0);
 
            } catch(Exception e) { System.out.println("Error: " +e); }
 
	}
 
	public void CheckStream() {
 
		while(true) {
 
			RECEIVE();
		}
 
	}
 
	public void RECEIVE() {
 
		if(INPUT.hasNext()) {
 
			String MESSAGE = INPUT.nextLine();
 
			if(MESSAGE.contains("ST,")) {
 
 
			   String[] reFeed = MESSAGE.split(",");
 
                           if(reFeed[0].contains("ST")) {
 
                    switch (reFeed[1]) {
                        case "1":
 
                            //Game has not started yet, lets get them in!
                            Bongo.LOC_Lobby();
 
                            break;
                        case "2":
 
                            //In Prep Time, Still Time To Get In!
                            Bongo.LOC_GameSetUp();
 
                            break;
                        default:
 
                            //Game has started so lets throw them in purgatory
                            Bongo.LOC_Wait();
 
                            break;
                    }
                           }
 
 
			} else {
 
                            System.out.println(""+MESSAGE);
			  //A_Chat_Client_GUI.TA_CONVERSATION.append(MESSAGE + "\n");
			}
		}
	}
 
	public void SEND(String X) throws IOException {
 
                OUT.println(Bongo.UserName + "," + X);
		OUT.flush();
 
 
	}
}

I do a check in the server with a simple System.out.println to tell me when the server receives anything from the client side but nothing..
The DISCONNECT function is called from here:

                MainWindow.addWindowListener(new WindowAdapter() {
                    public void windowClosing(WindowEvent e) {
 
                        try {
                            System.out.println("Gonna Disconnect!");
                            ChatClient.DISCONNECT();
                        } catch (IOException ex) {
                            System.out.println(Error: "+e+"\n");
                       }
                    }
                });

and this is the server side:

package gameserver;
 
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
import java.util.Scanner;
 
 
public class GameServer { 
 
    	public static ArrayList<Socket> ConnectionArray = new ArrayList<>();
	public static ArrayList<String> CurrentUsers = new ArrayList<>();
    	public static ArrayList<Socket> NGSocks = new ArrayList<>();
	public static ArrayList<String> NGUsers = new ArrayList<>();
 
 
 
    public static void main(String[] args) {
        GameFlow gf = new GameFlow();
        new Thread(gf).start();
 
        try {
 
            final int PORT = 444;
            ServerSocket SERVER = new ServerSocket(PORT);
            System.out.println("Waiting for Clients");
 
            while(true) {                 
 
                    Socket SOCK = SERVER.accept();
 
                    System.out.println("Client Connected from : " + SOCK.getLocalAddress().getHostName());
 
                    Scanner INPUT = new Scanner(SOCK.getInputStream());
                    String UserName = INPUT.nextLine();
 
                    String[] InFeed = UserName.split(",");
 
                    System.out.println("Got Here!! "+ InFeed[1] + "\n");
 
                    if(InFeed[1].equals("START")) { 
 
                        System.out.println("START envoked!!\n");
 
                        if(GameFlow.getMode() == 3) {
 
                                AddUserNextGame(InFeed[0], SOCK);
 
                            } else { 
 
                                AddUserName(InFeed[0], SOCK);
 
                        }                      
 
                        PrintWriter OUT = new PrintWriter(SOCK.getOutputStream());
                        OUT.println("ST," + GameFlow.getMode() + "," + GameFlow.getTime());
                        OUT.flush();                       
 
                    } else if (InFeed[1].equals("CLOSE")) {
 
                        for(int i = 1; i <= GameServer.CurrentUsers.size(); i++) {
 
                            if(CurrentUsers.get(i-1).equals(InFeed[1])) {
 
                                CurrentUsers.remove(i-1);
                                ConnectionArray.remove(i-1);
 
                            }
 
                        }
 
 
                    }
 
            }
 
	}catch(Exception e) { System.out.println(e); }
 
    }

thanks for any help...

I FINALLY figured this out:

I needed to just move thise code:

                    Socket SOCK = SERVER.accept();
 
                    System.out.println("Client Connected from : " + SOCK.getLocalAddress().getHostName());
 
                    Scanner INPUT = new Scanner(SOCK.getInputStream());

outside the while true loop..
