Jvm Performance Engineering: Inside the Openjdk Hotspot VM

Java SE 9 by Example teaches experienced programmers exactly how to take full advantage of Java SE 9's major, long-awaited improvements. Java Champion Monica Beckwith relies on extensive sample code reflecting real-world use cases to illustrate Java SE 9's key features and functions, and demonstrate the benefits of utilizing them.

Beckwith shows how Java's new module system ("Project Jigsaw") enables working developers to build solutions that scale easily from tiny devices to large and complex libraries; are more secure and maintainable; and deliver exceptional performance. She reviews Java SE 9 changes in areas ranging from data types and packages to classes and interfaces, showing how to make the most of Java's new tools and facilities. For example, you'll learn how to:

• Create, compile and write microbenchmarks using the JMH
• Create, compile and write a modular jar
• Take advantage of Java's new logging interface
• Take full advantage of the new default GC (garbage collection)
• Use sjavac, segmented code caches, and contended or uncontended object monitors
• And much more

If you're moving to Java SE 9 -- or want to know why you should -- Java SE 9 by Example is the book you've been waiting for.
