Virtual Threads, Structured Concurrency, and Scoped Values

Discover the exciting new APIs introduced by Java’s Project Loom. This quick guide covers all the essential concepts the Java developer needs in order to understand virtual threads, structured concurrency, and scoped values.

Authors Ron Veen and David Vlijmincx clearly explain the superiority of virtual threads, introduced in Java 21, over the traditional Java threads of the past 25 years. Then they dive into how structured concurrency streamlines interactions by treating related threads as a unified unit of work, akin to the impact of structured programming on regular programming. From there, the authors explore the third Project Loom API and scoped values, clarifying their advantages over regular ThreadLocals and providing efficient usage insights. The book concludes with an exploration of common scheduling strategies.

By the end of this book, you will have a solid understanding of the concepts behind Project Loom and will be able to immediately apply this knowledge to your own code.

Migrating to Cloud-Native technology with Jakarta EE: Transform your legacy Java EE project into a cloud native application

A pragmatic guide that will take an existing Java EE application and migrate it to the latest version of Jakarta EE and turn it into a cloud native and serverless application.

The book will start with a history of Jakarta EE. Next, we will introduce an example application that we will use throughout the book as a reference application. We will gradually upgrade this application to the latest features available in Jakarta EE. We will then show how the reader can upgrade his existing Jakarta EE application. First simply migrating the code to be compatible with the latest version. And then adapting it using the modern features.

Next, the reader will be introduced to containers and what it means to build a truly cloud-native application. This is done by bringing Eclipse Microprofile into the mix.

The next big step is moving the application from the reader's own hardware to managed hardware in the cloud. This will be done by making the application run on the Microsoft Azure cloud.

Finally, we will look at running services that run in a serverless architecture.

Technical reviewer of Java Coding Problems

The super-fast evolution of the JDK between versions 12 and 21 has made the learning curve of modern Java steeper, and increased the time needed to learn it. This book will make your learning journey quicker and increase your willingness to try Java’s new features by explaining the correct practices and decisions related to complexity, performance, readability, and more. Java Coding Problems takes you through Java’s latest features but doesn’t always advocate the use of new solutions — instead, it focuses on revealing the trade-offs involved in deciding what the best solution is for a certain problem. There are more than two hundred brand new and carefully selected problems in this second edition, chosen to highlight and cover the core everyday challenges of a Java programmer. Apart from providing a comprehensive compendium of problem solutions based on real-world examples, this book will also give you the confidence to answer questions relating to matching particular streams and methods to various problems. By the end of this book you will have gained a strong understanding of Java’s new features and have the confidence to develop and choose the right solutions to your problems.
