Working with JSON is a daily task in modern Java applications. Thanks to the Java 8 Stream API and the Jackson library, you can now process JSON data in a clean, functional style. Instead of writing verbose loops and conditionals, you can compose readable pipelines that handle filtering, mapping, and collecting with ease.
In this tutorial, we’ll walk through how to parse a JSON document and apply powerful filters using Java Streams. We’ll also cover best practices for Java 11+ and performance tips for handling large datasets.
