How to terminate a thread blocking on socket IO operation instantly

• Stackoverflow: How to terminate a thread blocking on socket IO operation instantly?

There are two ways to do this:

• Calling Thread.interrupt() will (under some circumstances that are not specified) interrupt a blocking I/O operation, causing it to throw an InterruptedIOException or ClosedByInterruptException.
• Calling Socket.close() on the socket will close the associated InputStream and OutputStream objects, and cause any threads blocked in Socket or (associated) stream operations to be unblocked. According to the javadoc, operations on the socket itself will throw a SocketException.
