Data-Oriented Programming With Java (30min)

Project Amber has changed the Java language over the last few years. New features have been added to the language with the aim of changing the way we use it. With records, sealed classes and pattern matching, Java now has OO and FP functionality.

This is the realm of data-oriented programming.

What it is, why you should consider it, and how you can apply it will be explained in this talk.

Deep Dive Into String Templates (30min)

Java has many ways of embedding variables in strings for formatting. But none of them were really satisfactory. Java developers have been crying out for decent string interpolation for years. And in Java 21 we got just that in the form of templates. But as you might expect from the language designers, this was not just a quick fix. It comes with a thorough API that developers can use to create their own implementations.

In this session, I will not only explain the benefits of the new templating system, but I will also code a custom implementation of this API to show the audience the enormous possibilities.
This will all be done in a live coding session.
