What is Phaser in Java? When and How to use Phaser? Example Tutorial

Hello guys, if you want to know what is Phaser and when and how to use Phaser in Java then you have come to the right place. Phaser in Java is a synchronization mechanism introduced in Java 7 that allows threads to wait for a certain phase or a set of phases to complete before proceeding further. It is a reusable barrier that allows threads to synchronize and wait for other threads to reach a certain phase before moving ahead. In the past, I have shared the best Concurrency courses and books and also wrote tutorials about popular Java concurrency utility classes like CyclicBarrier, CountDownLatch, BlockingQueue, ForkJoinPool, and recently CompletableFuture in this article, you will learn about Phaser, another useful concurrency utility for Java programmers.
