Description

There are several gems inside the existing concurrency API that have been hiding in the background for years, waiting to be discovered by curious software engineers. The existing Java Concurrency API makes it much easier to build a Java application that is scalable and performant without having to settle for lots of low-level wait-notify usage or lots of locking using the synchronized keyword. In this course, Scaling Java Applications Through Concurrency, you'll cover several concurrency patterns simplified by the Java Concurrency API; these patterns will make scaling new and existing Java applications simpler than ever. First, you'll learn about how the Java Concurrency API has changed scalability and how to run processes in the background. Next, you'll cover classes that will help you avoid mistakes like lost updates when sharing resources. Finally, you'll discover how to coordinate dependent processes and implementing throttling. By the end of this course, you will be able to easily scale your Java applications through concurrency so that they work better and faster.
