How to modify below simple chat system?Please help!

Question

Dear,
I have a ChatServer.java files as below. It is a round robin chating system. There are two client chatting. Now I want to modify below file that allow the discussion to keep going until one of the user input is "BYE" in uppercase without any preceding and trailing characters. After one user input of "BYE" will terminates everyone else including the server. How do I modifty? Please help!
import java.io.*;
import java.net.*;
public class ChatServer.java
// Valid PORT_NUMBER ranges from 1 to 65,535. However the numbers from 1 to 1023
// are reserved, for example, 80 is reserved for http.
private final static int PORT_NUMBER = 3030;
public static void main (String[] args) throws IOException
Socket socket1, socket2;
DataInputStream dataIn1, dataIn2;
DataOutputStream dataOut1, dataOut2;
String line;
System.out.println ( "\r\n-- Server Started --\r\n" );
// We need to create a ServerSocket at a free port number.
ServerSocket server = new ServerSocket ( PORT_NUMBER );
// Calling the accept method, the server waits for a client to make a TCP connection.
socket1 = server.accept ();
socket2 = server.accept ();
// ServerSocket is only needed to handle connection request. Once the connection
// is made, the ServerSocket can be closed even the sockets remain open.
// Normally, the ServerSocket won't be closed this early because real applications
// are designed to handle arbitrarily many clients. However we only handle two.
server.close ();
try
// There should be a pair of input and output streams for each socket.
// The output stream of the server corresponds to the input stream of the client.
// Therefore if we send a line on the output stream, the client should read
// the line in the corresponding input stream.
dataIn1 = new DataInputStream (new BufferedInputStream (socket1.getInputStream ()));
dataOut1 = new DataOutputStream (new BufferedOutputStream (socket1.getOutputStream ()));
dataIn2 = new DataInputStream (new BufferedInputStream (socket2.getInputStream ()));
dataOut2 = new DataOutputStream (new BufferedOutputStream (socket2.getOutputStream ()));
for ( int i=0; i < 3; i++)
// Read a line from the client 1
line = dataIn1.readUTF ( );
// Write a line to client 2
dataOut2.writeUTF ( line );
dataOut2.flush ( );
// Show the line on the server's screen
System.out.println ( "\r\nClient 1: " + line);
System.out.flush( );
// Read a line from the client 2
line = dataIn2.readUTF ( );
// Write a line to client 1
dataOut1.writeUTF ( line );
dataOut1.flush ( );
// Show the line on the server's screen
System.out.println ( "Client 2: " + line);
System.out.flush( );
catch (IOException ex)
throw ex;
finally
System.out.println ("\r\n-- Shutdown --");
socket1.close ();
socket2.close ();

In this section here do this:
The chat client 1:
// Show the line on the server's screen
String printTheLine="\r\nClient 1:" + line;
System.out.println (printTheLine);
System.out.flush( );
if(printTheLine.equals("\r\nClient 1:BYE"){
//exit prog
}Client 2
// Show the line on the server's screen
String printTheLine="\r\nClient 2:" + line;
System.out.println (printTheLine);
System.out.flush( );
if(printTheLine.equals("\r\nClient 2:BYE"){
//exit prog
}All you have to do is exit the prog. I am not sure if you need in the .eguals part (when you are comparing the strings), the \r\n. Anyway, once you put the code to exit your prog in the if conditionals, it will exit if the output on the screen looks like:
Client 1:BYE or
Client 2:BYE
If this helps, could I have some duke dollars?
