Ds.receive (DP);//blocking type. 4, through the method of the packet object, parse the data, such as address, port, data content. String IP = dp.getaddress (). gethostaddress (); int port = Dp.getport (); SYSTEM.OUT.PRINTLN ("----Port-----" + port); String text = new String (Dp.getdata (), 0, Dp.getlength ()); SYSTEM.OUT.PRINTLN (IP + "::" + text); if (Text.equals ("886")) {System.out.println (IP +) .... Exit chat room ");
