MongoDB Java Driver
Introduction
Welcome to the documentation site for the Java Driver, the official MongoDB driver for synchronous Java applications. Follow the Quick Start guide to learn how to add the driver to your project by using Maven or Gradle and how to set up a runnable app.
If your Java application requires asynchronous stream processing, use the Reactive Streams Driver which uses Reactive Streams to make non-blocking calls to MongoDB.
Connect to a Compatible MongoDB Deployment
You can use the Java Driver to connect to MongoDB deployments running on one of the following hosted services or editions:
MongoDB Atlas: the fully managed service for MongoDB deployments in the cloud
MongoDB Enterprise: the subscription-based, self-managed version of MongoDB
MongoDB Community: the source-available, free-to-use, and self-managed version of MongoDB
