The goal of project Amber within OpenJDK is to explore the inclusion of smaller, productivity-oriented Java language features. One part of this that has delivered new functionality in recent versions is pattern matching.
Pattern matching combines application code logic to test if an expression has a specific type or structure and extract components of its state for processing.
Pattern matching is now well embedded in the Java language using the following features, defined by JDK Enhancement Proposals (JEPs)
In this session, we’ll look at the details of these new language features and a more general look at pattern matching. We’ll also explore future features in this area such as array patterns, which may be included in a subsequent Java release.
By the end of the session, you’ll be ready to use these powerful new features.
