Connect multiple Clients to SocketServer

Am trying to connect multiple Clients to a Server, each Client is created inside
a Thread

while(true){
    ClientWorker w;
        try{
         w = new ClientWorker(server.accept());
         Thread t = new Thread(w);
         t.start();
     } catch (IOException e) {
         System.out.println("Accept failed: 4444");
     }
}

ClientWorker is a class with runnable interface, which handles InputStream and OutputStream.

So my question: Is the ClientWorker w created each time anew in the while (true) loop,
or
the the ClientWorker w will be overwritten each time the loop is run.

or do i have to initiate an Array to store all the ClientWorkers so each time a new Client is created?

thanx

If you need to keep the reference to each, yes. You could make them free-running so you don't need one

yes, with the variable w referencing the new ClientWorker.

> the the ClientWorker w will be overwritten each time the loop is run.

w will reference the new instance, but the existing instance will still exist.

so i kept the code, and each client could well send some string to the server.

my problem is if i want to send some string to ALL the connected clients,
it does not work.

How could i tell the OutputStream to all the connected Clients?

thanx :)

Iterate thru all client handlers and write the same thing to all outputs

Keep their references in a List/Set as they connect to server
