# Java SDK developer guide

> Explore Temporal Java SDK feature guides to master developing Temporal Applications. Build Workflows, Activities, and Workers, connect to Temporal Services, set up a testing suite, handle failure detection, send messages, complete Activities asynchronously, implement Versioning, use Observability, debug applications, schedule Workflows

## Install and get started

You can find detailed installation instructions for the Java SDK in the [Quickstart](/develop/java/set-up-your-local-java).

There's also a short walkthrough of how to use the Temporal primitives (Activities, Workflows, and Workers) to build and run a Temporal application to get you up and running.

Once your local Temporal Service is set up, continue building with the following resources:

- [Develop a Workflow](/develop/java/workflows/basics)
- [Develop an Activity](/develop/java/activities/basics)
- [Start an Activity execution](/develop/java/activities/execution)
- [Run Worker processes](/develop/java/workers/run-worker-process)

From there, you can dive deeper into any of the Temporal primitives to start building Workflows that fit your use cases.
