What is findOneAndUpdate?

In MongoDB development with Java, the findOneAndUpdate method is incredibly efficient. It allows you to search for a specific document and update it in a single operation. This ensures that your data remains consistent and your code stays clean.

Why Use This Method?

Unlike a standard update, this method can return the document as it was before the update or as it is after the update. It is perfect for cases where you need to know the previous state of your data while applying changes.

Key Steps to Follow:

• Set the Filter: Define which document you want to find (e.g., by ID or specific field).
• Define the Update: Specify the new values you want to apply to the document.
• Execute the Command: Call the method on your MongoDB collection object.
• Check the Result: Handle the returned document in your Java application.
