You can connect to your MongoDB deployment by providing a connection URI, also called a connection string, which instructs the driver on how to connect to a MongoDB deployment and how to behave while connected.
The connection string includes the hostname or IP address and port of your deployment, the authentication mechanism, user credentials when applicable, and connection options.
To connect to an instance or deployment not hosted on Atlas, see the Choose a Connection Target guide.
Find your MongoDB Atlas connection string.
To retrieve your connection string for the deployment that you created in the previous step, log into your Atlas account and navigate to the Clusters page under the Database section. Click the Connect button for your new deployment.

If you do not already have a database user configured, MongoDB will prompt you to create and configure a new user.
Click the Drivers button under Connect to your application and select "Java" from the Driver selection menu and the version that best matches the version you installed from the Version selection menu.
Ensure the View full code sample option is deselected to view only the connection string.
Update the password placeholder.
Paste this connection string into a file in your preferred text editor
and replace the <db_password> placeholder with your database user's
password. The connection string is already populated with your database
user's username.
Save this file to a safe location for use in the next step.
After completing these steps, you have a connection string that contains your database username and password.
