Class StructuredConcurrencyPreviewNotes

java.lang.Object
net.jrodolfo.java_evolution.java21.structured_concurrency.StructuredConcurrencyPreviewNotes
public class StructuredConcurrencyPreviewNotes extends Object
Explains structured concurrency as a Java 21 first preview feature.

Concurrent subtasks are easier to understand when they have a clear parent operation. Without that structure, child tasks can outlive the work that started them, and failure handling, cancellation, joining, cleanup, and observability can be spread across unrelated code.

Java 21 previewed structured concurrency so related concurrent subtasks could be managed as one structured unit of work. This package documents the first-preview step and points to the later Java 25 module for the fuller preview workflow.
