Unable to read from the stream in java

Question

I am using tcp socket for client server programming in java . After writing a message in the outputstream , I started to read the inputstream and I continues the reading till the inputstream returns -1(EOF). But its not returning -1, I got stucked. Please give your suggestions. Look at the code below.

int bytesRead = tcpSocket.readPacket(buffer);
while(bytesRead != -1) {
    builder.append(new String(buffer, 0, bytesRead));
    bytesRead = tcpSocket.readPacket(buffer);
}

Answer 1

If its a Socket then -1 would be returned when the connection is terminated (normally).

In your case, I would guess that there is no further data coming through but it is not returning -1 either.
