Thread, Returning

[ronnyjljr]

Hello,

This is my first run at a client/server application.
Basically I start the server use the ServerSocket and bind it to the port. Next I listen for the client connection and upon receiving it I start a new thread which in turns allows for multiple clients to log on.

public static void main(String[] args) throws IOException
	{		
		try
		{			
			StartDate = new Date(System.currentTimeMillis());
		System.out.println("Binding...");
		serverSocket = new ServerSocket(SERVERPORT);
		System.out.println("Bound! Waiting for connection....");
		}
		catch (IOException e)
		{
			System.out.println("Unable to bind! \n" +e.toString());
		}
				
		while(ClientCount<4)
		{
			try
			{
				clientSocket = serverSocket.accept();
				ClientCount++;
				new Client(clientSocket,StartDate).start();
			}
			catch (IOException e1)
			{
				e1.printStackTrace();
			}
		}

This works fine and dandy. What I want to do is to be able to return something from that client thread, for instance, maybe the client gave authorization to shutdown the server. How would I go about passing a string or other object back from the thread? Do I need to create some sort of listener?

Thanks,
Ron

Well, one way to do this is passing to the thread object a reference from the caller and implement one method the thread object can call to notify events or returning values.

Cheers,
