Overview of this book

Writing concurrent and parallel programming applications is an integral skill for any Java programmer. Java 9 comes with a host of fantastic features, including significant performance improvements and new APIs. This book will take you through all the new APIs, showing you how to build parallel and multi-threaded applications. The book covers all the elements of the Java Concurrency API, with essential recipes that will help you take advantage of the exciting new capabilities. You will learn how to use parallel and reactive streams to process massive data sets. Next, you will move on to create streams and use all their intermediate and terminal operations to process big collections of data in a parallel and functional way. Further, you’ll discover a whole range of recipes for almost everything, such as thread management, synchronization, executors, parallel and reactive streams, and many more. At the end of the book, you will learn how to obtain information about the status of some of the most useful components of the Java Concurrency API and how to test concurrent applications using different tools.

Running concurrent-phased tasks


One of the most complex and powerful functionalities offered by the Java concurrency API is the ability to execute concurrent-phased tasks using the Phaser class. This mechanism is useful when we have some concurrent tasks divided into steps. The Phaser class provides us with a mechanism to synchronize threads at the end of each step, so no thread will start with the second step until all the threads have finished the first one.

As with other synchronization utilities, we have to initialize the Phaser class with the number of tasks that participate in the synchronization operation, but we can dynamically modify this number by either increasing or decreasing it.

In this recipe, you will learn how to use the Phaser class to synchronize three concurrent tasks. The three tasks look for files with the extension .log modified in the last 24 hours in three different folders and their subfolders. This task is divided into three steps:

  1. Get a list of the files with the...
