java - System.out.println always outputs HASH(0x........) -


the system.out.println statement below outputs logcat hash reference "hash(0x....)" whether or not specify variable printed "line" or "line.tostring()". how print actual string value?

url object=new url(url); httpurlconnection con = (httpurlconnection) object.openconnection(); con.setdooutput(true); con.setdoinput(true); con.setrequestproperty("content-type", "application/json"); con.setrequestproperty("accept", "application/json");  try {     con.setrequestmethod("post"); } catch (protocolexception e) {     e.printstacktrace(); }  outputstreamwriter wr; try {     wr = new outputstreamwriter(con.getoutputstream());     wr.write(json.tostring());       wr.flush(); } catch (ioexception e) {     e.printstacktrace(); }                         int httpresult = con.getresponsecode();  if (httpresult == httpurlconnection.http_ok) {     bufferedreader br = new bufferedreader(new inputstreamreader(con.getinputstream(),"utf-8"));      string line;       while ((line = br.readline()) != null) {           system.out.println("line: " + line.tostring());     }       br.close();   }

there's nothing wrong code. replace code above loop simpler, like:

        fileinputstream fstream = new fileinputstream("somefile");         bufferedreader br = new bufferedreader(new inputstreamreader(fstream,"utf-8"));          string line;          while ((line = br.readline()) != null) {               system.out.println("line: " + line);         }           br.close();

and see content of file.

note didn't need .tostring() because variable string.

what suspect here server sending compressed body, , each line hash because definition of compression, in hex.

the content json, compressed improve size , speed.
