See what’s in the program!
Stream API was introduced to Java over a decade ago, but since then it hasn’t seen any major improvements… until JEP 485: Stream Gatherers arrived. This small revolution breathes new life into the Stream API. During this session, we’ll explore JEP 485 — the biggest change to the Stream API in the last 10 years — scheduled to arrive in Java as early as March 2025!
At #96 Talk4Devs, we will:
- dive into the anatomy of the Stream API and Gatherers,
- explore the built-in Gatherers and create a few custom ones,
- break down the Collector and Gatherer APIs piece by piece,
- take a closer look at ready-made Gatherer implementations from the standard library (including those enabling parallel stream processing on virtual threads),
- and, most importantly, extend the Stream API by building several custom implementations of our own.
We’ll be live coding throughout the session — as Grzegorz puts it: “my conscience clause doesn’t allow me to use slides!”
