What’s New for Concurrency in Java SE 8?

Java logo

Java SE 8 was officially released yesterday (March 18th) and given the fact that Java 7 was released back in 2012, there are definitely lots of updates and new features. These updates include improvements to the Java language itself, Java security, Java tools and more. Although a lot of these updates are interesting and important I am specifically interesting in exploring: What’s new for concurrency?

Based on the release notes the concurrency-related additions are:

“…internally employ contention-reduction techniques that provide huge throughput improvements as compared to Atomic variables.”

The complete Java SE 8 release notes are available here and complete details on the concurrency enhancements are available here.
