Check if an inputream is empty

Question

In my application I use socket to communication with another device how I can check if inputStream is empty ? In this line I have a java.net.SocketTimeoutException

while ((bytesRead = inputStream.read(content)) != -1) {

Define 'empty'. The timeout has already told you there is no data available *now*, but that doesn't mean there never will be. There's generally no need to move beyond read timeouts. — user207421, Nov 08 '17 at 09:21

Try inputstream.available(). It returns an estimate of the number of bytes that can be read from this input stream without blocking by the next invocation of a method for this input stream.

Read the javadoc of the method: "The available method for class InputStream always returns 0". – Pavel Leonov Feb 23 '20 at 09:40
