MONGODB Java Integration ~ GNIITHELP

Java Integration in MongoDB

In this, we will learn how to integrate MongoDB with Java and will explore the basic CRUD (Create, Retrieve, Update and Delete) operations.

Download Jar, use mongo-java-driver-2.10.1.jar. Add jar to the Java build path. Now, we are ready for performing CRUD operations with MongoDB through Java.

Here, we are making use of MongoDB Compass – a GUI tool for MongoDB for visualizing our query output.

When above lines of code are executed, Collection User will be created in Database. We can check our query output through MongoDB Compass.
