Multiplayer Flash Game Help!

Look like this is code of simple Echo-like server. There is nothing about game or coordinates of any kind. All you can do is send to server string like: "x?" and recive answer like "x=100". Is this a game? :)

Well, code should be followed:

import java.io.*;

import java.net.*;

public class simpleServer

{

public static void main( String[] args )

{

// Message terminator

char EOF = ( char )0x00;

try

{

// create a serverSocket connection on port 9999

ServerSocket s = new ServerSocket( 9999 );

System.out.println( "Server started. Waiting for connections..." );

// wait for incoming connections

int x = 100, y = 100;

while( true )

{

Socket incoming = s.accept( );

BufferedReader data_in = new BufferedReader(

new InputStreamReader(incoming.getInputStream( ) )

);

PrintWriter data_out = new PrintWriter(incoming.getOutputStream());

data_out.println( "Welcome! type EXIT to quit." + EOF );

data_out.flush( );

boolean quit = false;

// Waits for the EXIT command

while( !quit )

{

String msg = data_in.readLine();

if( null == msg)

quit = true;

if( msg.trim( ).equals( "X?" ) )

{

data_out.println( "X = " + x + EOF );

data_out.flush( );

}

else

if( msg.trim( ).equals( "Y?" ) )

{

data_out.println( "Y = " + y +EOF );

data_out.flush( );

}

else

if( msg.trim( ).equals( "X+" ) )

{

x++;

data_out.println( "X increased" + EOF );

data_out.flush( );

}

else

if( msg.trim( ).equals( "Y+" ) )

{

y++;

data_out.println( "Y increased" + EOF );

data_out.flush( );

}

else

if( msg.trim( ).equals( "X-" ) )

{

x--;

data_out.println( "X decreased" + EOF );

data_out.flush( );

}

else

if( msg.trim ().equals( "Y-" ) )

{

y--;

data_out.println( "Y decreased" + EOF );

data_out.flush( );

}

else

if( msg.trim( ).equals( "EXIT" ) )

{

data_out.println( "Bye!" + EOF );

data_out.flush( );

quit = true;

}

else

{

data_out.println( "You sayed: <b>" + msg.trim( ) + "</b>" + EOF );

data_out.flush( );

}

}

incoming.close( );

}

}

catch( Exception e )

{

System.out.println( "Connection lost, shutting down..." );

}

}

}
