How to check if readUTF method has some value to receive or not

Question

I am implementing a server client application in java. Situation is that client sends some message to server and server may or may not respond(send back some message).

Have a look at this

is = new DataInputStream(client.getInputStream());

Now i am using is.readUTF(); method to get the message back.

Problem is that readUTF is a blocking call and it stops the program right there to receive a message. As i said that server may or may not respond and i need a way to stop the readUTF method from stopping the program(checking if there is a message or not) and keep on continue if there is no message received.

Make the server respond in any case. Also, if the client can continue before receiving the answer, communicate in a second thread. — xehpuk, Oct 04 '16 at 13:46

Use DataInputStream.available() to check whether there is data to be read and wrap the socket's InputSteam with a PushbackInputStream as described here.
