🎬 Online "#OOP vs. Data Oriented Programming: Which One to Choose?" by #CoffeeJug! ☕️ #java #jug
📅 Date: 25 Sep (Thursday)⏰ Time: 7:00 PM - 8:30 PM EET🎤 Speaker: Venkat Subramaniam, Founder @ Agile Developer, Inc.🆓 Entrance is FREE! (Pre-registration required) https://forms.gle/fKHhrJe5x4cfXx5j7More details: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.#CoffeeJUG #Java #OOPCoffeeJug - monthly events for #Java professional (#javausergroup).

However, Java turns out to evolve so fast, that next releases aren’t just version bumps, but might significantly change the rules of the game. That’s a good reason to check out what’s new in Java.
