Java Multithreading: AtomicReference, ScheduledExecutorService, and the Either monad. Multithreadin
In one of the past videos, we looked at locks in the Java language, how and when to use them - • Synchronized vs ReadWriteLock vs Stam... .
In this video, we will change a little the task from the last video to get familiar with the ScheduledExecutorService, AtomicRefrerence and the Either monad!
Happy viewing!
