How to interrupt BufferedReader's readLine

Question

I am trying to read input from a socket line by line in multiple threads. How can I interrupt readLine() so that I can gracefully stop the thread that it\'s bl

Answer 1

I was playing around with this recently (using Scala), and I didn't like the accepted answer of closing the socket and getting an exception.

Eventually I discovered that it's possible to call socket.shutdownInput() in the interrupting thread to get out of the readLine call without an exception. I make this call in a SIGINT handler so that I can clean up and close the socket in the main thread.

Note, that the equivalent exists for the outputstream with socket.shutdownOutput()
