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 appear 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. Presented by Venkat Subramaniam (Agile Developer, Inc.) at JavaOne 2026 (CA, March 2026).
