Rational Java: Let's pause for a Microsecond

    http://www.rationaljava.com/2015/10/measuring-microsecond-in-java.html
    Oct 28, 2015 · Another option when we want to pause for a microsecond is to use LockSupport.parkNanos(x). Using the following code to park for 1 microsecond actually takes ~10us. It's way better than TimeUnit.sleep() / Thread.sleep() but not really fit for purpose. After 100us it does get into the same ball park with only a 50% variation.

Thread.sleep() Alternatives : java

    https://www.reddit.com/r/java/comments/2d48qm/threadsleep_alternatives/
    I was wondering if there were any alternatives to Thread.sleep(), especially since if I use it in one method of my class, I always have to put in the exception and it gets annoying after a few dozen classes. I'm using the console at the moment, but I'll take any alternative.

LockSupport (Java Platform SE 7 )

    https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/locks/LockSupport.html
    Basic thread blocking primitives for creating locks and other synchronization classes. This class associates, with each thread that uses it, a permit (in the sense of the Semaphore class). A call to park will return immediately if the permit is available, consuming it in the process; otherwise it may block. A call to unpark makes the permit available, if it was not already available.
