Finally, a book that focuses on the practicalities rather than theory of Java application performance tuning. This book will be your one-stop guide to optimize the performance of your Java applications.

We will begin by understanding the new features and APIs of Java 9. You will then be taught the practicalities of Java application performance tuning, how to make the best use of garbage collector, and find out how to optimize code with microbenchmarking. Moving ahead, you will be introduced to multithreading and learning about concurrent programming with Java 9 to build highly concurrent and efficient applications. You will learn how to fine tune your Java code for best results. You will discover techniques on how to benchmark performance and reduce various bottlenecks in your applications. We'll also cover best practices of Java programming that will help you improve the quality of your codebase.

By the end of the book, you will be armed with the knowledge to build and deploy efficient, scalable, and concurrent applications in Java.

He is the CEO of a software company, Zonopact, Inc. headquartered in Boston, USA, which specializes in bringing innovative applications based on AI, robotics, big data, and more. He has single-handedly developed Zonopact’s flagship product, Clintra (B2B-integrated AI-assisted business management software). He is also the inventor of two patent pending technologies, ZPOD (an automated cloud-based medical kiosk system) and ZPIC (an AI-enabled robotic in-car camera system). Apart from this, he is also a prolific business writer who has authored two international award-winning books, Unbarred Innovation: A Pathway to Greatest Discoveries and Evolve Like a Butterfly: A Metamorphic Approach to Leadership.

He was featured on the TV and in print media, including Fox News, NBC News, CBS News, Fox Business, Bloomberg International TV, Forbes, Inc. magazine, Daily Mirror, and The Huffington Post. He is also a contributing author of New York Daily Newspaper, the Software Development Times magazine, Newsmax Finance, AlleyWatch, Singapore's top entrepreneurship magazine Young Upstarts, and several more. He is frequently invited as a guest lecturer at various technical and management schools. He has also been invited as a judge at an international innovation challenge competition (Living Talent) in Dubai in December 2017.

Nick Samoylov

Nick Samoylov was born in Moscow, raised in Ukraine, and lived in the Crimea. He graduated as an engineer-physicist from Moscow Institute of Physics and Technologies and has even worked as a theoretical physicist. He has learned programming as a tool for testing his mathematical models using FORTRAN and C++.

After the demise of the USSR, Nick created and successfully ran a software company, but was forced to close it under the pressure of governmental and criminal rackets. In 1999, with his wife, Luda, and two daughters, he emigrated to the USA and has been living in Colorado since then.

Nick adopted Java in 1997 and used it for his work as a software developer-contractor for a variety of companies, including BEA Systems, Warner Telecom, and Boeing. For Boeing, he and his wife, also a Java programmer, developed a system to load application data to an airplane via the internet.

Nick's current projects are related to machine learning and developing a highly scalable system of microservices using non-blocking reactive technologies, including Vert.x, RxJava, and RESTful webservices on Linux deployed in a cloud.

Nick and Luda have two daughters who graduated from Harvard and Tufts universities, respectively. One of their daughters has also received a doctoral degree from Brown University and now works as a professor in the University of California in Chico. Their other daughter is an executive director of the investment bank JPMorgan, in Madrid, Spain.

In his free time, Nick likes to read (mostly non-fiction), write (fiction novels and blogs), and hike the Rocky Mountains.
