What does java.lang.Thread.interrupt() do?

Question

Could you explain what java.lang.Thread.interrupt() does when invoked?

Answer 1

An interrupt is an indication to a thread that it should stop what it is doing and do something else. It's up to the programmer to decide exactly how a thread responds to an interrupt, but it is very common for the thread to terminate.
