Concurrency is a dreaded topic for many developers. A good understanding of concurrency could get you level up from junior to medior. This course will teach you concurrency in Java.

For many developers, concurrency is one of the most complex topics. It is also mandatory for the OCP11 exam, but don't worry! In this course, Implementing Concurrency in Java (Java SE 11 Developer Certification 1Z0-819), you’ll learn to implement concurrency using Java SE. First, you’ll explore the basics and what concurrency is by starting with creating threads. Next, you’ll discover the different executors in Java and how to use several strategies such as the join/fork framework. Finally, you’ll learn how to identify and solve threading problems, such as deadlocks and livelocks. When you’re finished with this course, you’ll have the skills and knowledge of concurrency in Java needed to implement it in applications and ace the questions about this topic on the OCP11 exam.
