java - Asyncrhonous socket client -


i'm developing asynchronous socket client based on threads. when program calls readline(), blocks indefinitely , never returns.

public class adnclient {    socket socket = null;   dataoutputstream dataoutputstream = null;   datainputstream datainputstream = null;    thread listener = new thread(new runnable() {     @override     public void run() {       string line;       try {         // stop here , doesn't progress         while ((line = datainputstream.readline()) != null) {           //do         }       }        catch (ioexception e) {}     });      public adnclient() {     try {       socket = new socket("192.168.1.5", 5000);       dataoutputstream = new dataoutputstream(socket.getoutputstream());       datainputstream = new datainputstream(socket.getinputstream());       listener.start();       //sender.start();     } catch (exception e) {       log.e("adn", e.getmessage());     }   }    public void close() {     listener.stop();     try {       socket.close();     } catch (ioexception e) {       log.e("adn", e.getmessage());     }   } }

ok... i'm noob in/outputstreams... didn't send newline character, correct way recive information using

readutf()

instead of 

readline()

thank greg kopff!
