java - why the separate threads are not created? -

i new socket programming , trying write simple cmd line chat application. use code below accept connection , create new thread same,but no new thread created ,and no more 1 clients supported(which usual when threads not used),

public class chatserver extends thread{     public static socket client;     public static void main(string a[]) throws exception{         serversocket srv = new serversocket(4444);         if((client = srv.accept())!=null){             new newthread(client);         }     } } class newthread extends thread{     private socket client;     public newthread(socket client){         super("chatchild");         this.client = client;         start(); } 

why threads not created?i reffered examples @ "oracle.com" 1 of contains code same not able figure out exact sequence happen , when???the snippet exaple code accepts connection , creates thread::

while (listening)         new kkmultiserverthread(serversocket.accept()).start(); 

now here listening bool var sat true never set false anywhere in code.???how work?

you have continually call accept() create other threads:

public static void main(string a[]) throws exception{     serversocket srv = new serversocket(4444);      while (listening) {         new newthread(srv.accept());     } } 

the listening variable should set false if , when want stop server.
