It not only provides detailed insights into the inner workings of the Java virtual machine (JVM), but also equips you with the knowledge necessary to excel in building scalable and resilient applications using a variety of powerful techniques such as Spring Boot, Spring Native, GraalVM, and other innovative methodologies. Furthermore, the book assists you in navigating the complexities of testing and packaging, helping you comprehend and navigate intricate processes. It also introduces you to cutting-edge deployment methodologies that leverage Docker and Kubernetes, ensuring that you stay up to date with the most recent advancements in software development and deployment practices.

By the time you finish reading this book, you will have upgraded your Java programming techniques and gained the ability to fully exploit the latest and greatest advancements in the language.

What you will learn:
- Explore different techniques for developing multithreaded applications in Java.
- Harness the power of modern Java and Spring Boot 3+ to elevate your server development capabilities.
- Utilize the power of Docker, Kubernetes, and Spring Native to streamline your cloud-based deployments.
- Integrate unit testing, Mockito, and continuous integration (CI) into your Java projects.
- Use Prometheus and Grafana to monitor the performance of your Java applications.

Java has a big problem. It is often perceived as old, but Python is older, and jаvascript is its contemporary. Why is that? Java has had continuous popularity and success for nearly three decades. That means that most of us worked with Java 1.4, which was released two decades ago. Unlike any other platform out there, Java is still compatible with that release. That is fantastic but also creates a sense of disconnect. Developers compare that highly outdated version of Java to modern incarnation of other languages or platforms. That is an unfair comparison, and Java is a victim of its own success. There are several sources for information about new Java features but there is a lack in a comprehensive introductory guide to modern Java, that carries us from that old version to the modern world. With this book, we hope to fill that gap, to answer the question of “is this still the right way to solve this problem?”. This book is divided into 10 chapters. They cover Java basics, OOP basics and continue to cover everything we need to know, in order to build a modern Java backend.

Who this book is for:
This book is suitable for individuals who are new to Java and have little to no experience but possess a basic understanding of the syntax. Additionally, it provides valuable insights for developers who may have not utilized Java in a significant timeframe.
