Java: High-Performance Apps with Java 9

By: Ramgir

Overview of this book

Java 9 which is one of the most popular application development languages. The latest released version Java 9 comes with a host of new features and new APIs with lots of ready to use components to build efficient and scalable applications. Streams, parallel and asynchronous processing, multithreading, JSON support, reactive programming, and microservices comprise the hallmark of modern programming and are now fully integrated into the JDK. This book focuses on providing quick, practical solutions to enhance your application's performance. You will explore the new features, APIs, and various tools added in Java 9 that help to speed up the development process. You will learn about jshell, Ahead-of-Time (AOT) compilation, and the basic threads related topics including sizing and synchronization. You will also explore various strategies for building microservices including container-less, self-contained, and in-container. This book is ideal for developers who would like to build reliable and high-performance applications with Java. This book is embedded with useful assessments that will help you revise the concepts you have learned in this book. This book is repurposed for this specific learning experience from material from Packt's Java 9 High Performance by Mayur Ramgir and Nick Samoylov

Chapter 2. Tools for Higher Productivity and Faster Application

Since the dawn of programming as a profession, the standing goals of every aspiring coder were to quickly produce applications that perform the assigned tasks with lightning speed. Otherwise, why bother? We could slowly do whatever we were doing for thousands of years. In the book of the last century, we made substantial progress in both aspects, and now, Java 9 makes another step in each of these directions.

Two new tools were introduced in Java 9, JShell and the Ahead-of-Time (AOT) compiler--both were expected for a long time. JShell is a Read–Eval–Print Loop (REPL) tool that is well-known for those who program in Scala, Ruby, or Python, for example. It takes a user input, evaluates it, and returns the result immediately. The AOT compiler takes Java bytecode and generates a native (system-dependent) machine code so that the resulting binary file can execute natively.

These tools will be the focus of...
