Livelock is a scenario in which two or more block each other by

responding to an action caused by another thread.

In a deadlock situation two or more threads wait in one specific

state.

In a Livelock scenario, two more threads change their state in such a

way that it prevents progress on their regular work.

E.g. Consider scenario in which two threads try to acquire two

locks. They release a lock that they have acquired, when they cannot

acquire the second lock.

In a Livelock situation, both threads concurrently try to acquire the

locks. Only one thread would succeed, the second thread may

succeed in acquiring the second lock.

Now both threads hold two different locks. And both threads want

to have both locks. So they release their lock and try again from the

beginning. This situation keeps repeating multiple times
