HI
I have an applet and I need do some I/O
this blocks applet thread .. this stops applet thread painting, receiving mouse events etc
so what I have did that the class that does the I/O to implement the Runnable interface

how ever I do not know how to do communcition between applet thread and the thread the does the I/O

basically when the thread that does the
IO stops reading from a URLConnection
I want to call the updateGUI()

how can I determine that the IO thread
has stopped and so that I can update the swing components..

I have not really used threads before so I would appreciate if some one could give some basic ideas...

thanks>>>

			{
			

			public void run()
			

			{
			

			try
			

			{
			

			InputStream in = anotherObject.getData();
			

			

			BufferedReader reader = new BufferedReader(new InputStreamReader(in));
			

			

			while ((line= reader.readLine())!=null)
			

			{
			

			appendResult(line);
			

			}
			

			reader.close();
			

			in.close();

			public synchronized  String getResultBuffer()
			

			{
			

			

			String result = buffer.toString();
			

			buffer = new StringBuffer();
