In this chapter, you covered how pattern matching would change your everyday code. Pattern matching introduces a new keyword, matches, to ease the checking, casting, and retrieval of values from instances.

This book took you through the latest Java versions—10, 11 and 12, and also Project Amber. Java has a strong development road map and it continues to excite the developers and enterprises with its existing features and new capabilities. With a new six-month release cadence, Java is advancing at a fast pace that we haven't witnessed earlier. As developers, you get to work with newer Java features and improvements, sooner than ever before.

I encourage all developers to check out the improvements and additions to new Java versions, as they are released. Also, don't miss to browse through projects such as Valhalla, Loom, Panama, and many other projects at Oracle's website. These projects will advance Java's capabilities such as light-weight threading, simpler access to foreign libraries, and newer language candidates such as value types and generic specialization. Stay tuned!
