I'm trying to send an message from Java client to C++ server using ProtoBuf over socket. My program hangs while i am trying to create InputStream. Thanks in advance if some one could help me on this and here is my part of client code in java:

String host = "xxxxxxxxx";
int port = xxxx;

Builder builder = CarSelection.Car.newBuilder();
builder.setLabel("Audi");
builder.setValue("A6");

Car car = builder.build();
Socket client = new Socket(host, port);

byte[] result = car.toByteArray() ;  
car.writeDelimitedTo(client.getOutputStream());

Car recieveData= car.parseDelimitedFrom(client.getInputStream());

It is able to write to output stream but my program hangs when trying to read from input stream.

Are you trying to read and write from the _same_ application? From Java at both ends? – Louis Wasserman Sep 28 '17 at 18:18
What happens in `writeDelimitedTo` and `parseDelimitedFrom`? – Oleg Sep 28 '17 at 18:20
the other end is written in C++, i am trying to write a java client to get the data from c++ – Java coder Sep 28 '17 at 18:21
