Welcome to the official MongoDB Java driver documentation.
Connect your Java applications to MongoDB and work with your data using the Java driver. This documentation is for the synchronous Java driver. The synchronous Java driver runs your operations on MongoDB sequentially rather than in parallel. We recommend using the synchronous driver with your application.
If you're working with asynchronous stream processing and reactive streams, use the official MongoDB Reactive Streams driver instead.
On this page, you can read descriptions of each section of the documentation.
Learn how to establish a connection to MongoDB Atlas and begin working with data in the Quick Start section.
For fully runnable code snippets and explanations for common methods, see the Usage Examples section.
