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

  1. The _______ interface was introduced in Java 8 to emit elements and supports a variety of operations that perform computations based on stream elements.

  2. Which of the following factory methods of the StackWalker class creates a StackWalker class instance with the given option of specifying the stack frame information that it can access?

    1. getInstance()

    2. getInstance(StackWalker.Option option)

    3. getInstance(Set<StackWalker.Option> options)

    4. getInstance(Set<StackWalker.Option> options, int estimatedDepth)

  3. State whether True or False: The CompletableFuture API consists of many methods which are implementations of the CompletionStage interface, and are the implementations of Future.

  4. Which among the following methods is used when a type of filtering is required to skip all the duplicate elements in a stream and select only unique element.

    1. distinct()

    2. unique()
