In this chapter, we covered some impressive new features of the Java platform introduced with Java 9, 10, and 11. We focused on javac, JDK libraries, and various test suites. Memory management improvements, including heap space efficiencies, memory allocation, and improved garbage collection represent a powerful new set of Java platform enhancements.
