java - InputStream reader blocking thread -

i wrote inputstream reader listen socket. code in while(!stop) loop inside run method of thread. reader blocks thread, , not print message.

int read = 0; byte[] buf = new byte[512]; int index = 0; try {     while (!stop && (read = in.read()) != -1) {         system.out.println("read loop");         buf[index++] = (byte) read;     } } catch (ioexception e) {     e.printstacktrace(); } 

the read indeed blocks thread running if no data available.

what want read byte timeout ?

look answer in is possible read inputstream timeout?
