6:15-7:45: Structured Concurrency in Action

In Java 25, the structured concurrency API sees its fifth preview with considerable changes over previous iterations. With chances being good that it will finalize without a further overhaul, let's put it into action and explore how to:

* structure concurrent code
* process and propagate errors and cancellation
* observe thread relationships
* refactor from a reactive approach

After this presentation, you'll be ready to put the structured concurrency API into action in your project.
