At the end of this guide, you will have created a simple Java console
Hello, World! program that connects to the Memgraph database and executes simple queries.
For this guide you will need:
- A running Memgraph instance. If you need to set up Memgraph, take a look at the Installation guide.
- A basic understanding of graph databases and the property graph model.
- Java 8 or 11 installed.
We'll be using Eclipse IDE 2020-09 on Windows 10 to connect a simple Java console application to a running Memgraph instance using Maven.
If you're using a different IDE, the steps might be slightly different, but the code is probably the same or very similar.
Let's jump in and connect a simple program to Memgraph.
1. Open Eclipse and create a new Maven project.
2. Select the Create a simple project option.
3. For the Group Id field put
com.memgraph.app and for Artifact Id put
my-app. Afterwards, click the Finish button.
4. Open the
pom.xml file and add the following dependency:
5. Create the
HelloWorld.java program and copy the following code:
Once you run the program, you should see an output similar to the following:
For real-world examples of how to use Memgraph, we suggest you take a look at the Tutorials page. You can also browse through the Database functionalities section to get an overview of all the functionalities Memgraph offers.
