REGISTER FOR THE LIVESTREAM

Session abstract

JDK 24 is bringing a new enhancement to the Stream API, called the Stream Gatherer API. Stream Gatherers are a great addition to the Stream API, bringing new possibilities and helping to solve complex problems. This presentation shows you how Gatherers work on live examples, how you can create them, and what use cases they are most suitable for. Understanding Gatherers requires a good understanding of the Stream API. At the end of this presentation, you will be able to create your own Gatherers and understand when you should use them in your application.

Asking questions

José will try to answer all of your questions during the session. If we run out of time, we’ll publish answers to any remaining questions in a follow-up blog post.
