Executor Service - timeout of thread

Question

While I was exploring ExecutorService, I encountered a method Future.get() which accepts the timeout.

The Java doc of this method

Answer 1

my callable will interrupt after the specified time(timeout) has passed

The above statement is wrong, Usually Future.get is blocking. Specifying the timeout allows you to use it in a non blocking manner.

This is useful for instance in time critical applications, if you need a result within let's say 2 seconds and receiving after that means you can't do anything with that.
