Innovations have transformed human lives, in ways that we can't imagine how people survived before. Yet, we do not embrace innovations readily and we shouldn't in most cases. Our time in this world is juxtaposed with yet another major innovation in our field. Is AI going to take over the world, our jobs, our way of life...and more are questions that are asked frequently these days. Come to this keynote to learn how to ride the new wave instead of being swept under.

We rely heavily on polymorphism when programming with the object-oriented paradigm. That has served us really well, especially to create extensible code. However, like any tool and technique, there are times when that may not be the right choice. Java now provides an alternative that is useful in those select situations—the data-oriented programming. In this presentation we will start with an example where the highly useful object hierarchy and polymorphism appears as a misfit and discuss how data-oriented programming solves the problem more elegantly. Get a good understanding of when to use each one of these and how to intermix them in your applications.
