Description

In this lab you will learn how to deal with dynamic features such as reflection when compiling Java applications ahead-of-time using GraalVM Native Image.

You will:

• Learn how to build Java code that uses reflection into standalone executables, using the native-image tool.
• Learn about the assisted configuration tooling available with GraalVM.

GraalVM Native Image makes it possible to compile any Java application ahead-of-time into a native executable that starts almost instantaneously, provides peak performance with no warmup, and requires less memory and less CPU. It's perfect for containerized workloads and microservices—which is why it has been embraced by Micronaut, Spring Boot, Helidon, and Quarkus.
