Java interrupt thread when reading socket [duplicate]

Answer 1

The NIO Channels have InterruptableChannels which will be interrupted on blocking operations. You can use NIO with blocking operations so they work much the same as Java IO i.e. you don't have to redevelop your application to use Selectors/Dispatchers etc.

Answer 2

It has been answered How to terminate a thread blocking on socket IO operation instantly?

Basically, when you close() the socket, all the associated streams will close, causing all the blocked operations to be unblocked.

Or you can call Thread.interrupt() and it will interrupt the blocking operation causing it to throw the InterruptedException.
