Advanced Java: Threads and Concurrency

Course details

Are you looking to boost your Java skills? In this course, join instructor and Java expert Buddhini Samarakkody as she provides an overview of Java threads and the new concurrent programming model. Buddhini covers topics in synchronization such as Java thread memory access and associated problems such as race condition and data race. Explore the purpose of synchronization and how to use it, before turning to asynchronous programming with Future and CompletableFuture. Buddhini shows you how to use executors, the fork/join framework and its core classes, concurrent data structures, Project Loom, and virtual threads. Along the way, be sure to test out your new skills in the exercise challenges at the end of each section.
