Modern Java Course - Spring Native | learn java

In this installment of the course we talk about Spring native and GraalVM. We cover the changes needed for Spring Native and how it can be used. We then compare the overhead of Spring on JDK 19 to the GraalVM native image in a hello world Spring application.

You can find the full source code shown in the video (and in other videos in the series) here: https://github.com/shai-almog/java-book/

Many developers learned Java at a job or in University. In those settings it might have been Java 6 or 7 at best. A lot has changed in Java since then. Its become a modern powerful platform with, fluid syntax, high performance and low overhead.

In this course we'll go over the features of modern Java. We start by creating a baseline with Java 8 features. We then cover the features of Java releases up to version 21 and beyond. The course doesn't just cover the core Java API and VM. It goes into the deeper underlying concepts, all the way into Spring Boot, Kubernetes and using Java in a modern cloud environment.

This course aims to update weekly, please use the comments section below to ask questions and make requests. We'll try to help.
