Hi, You will need to install Java to run Neo4j from the command line, the documentation has information about which version to use and platform specific guidance.

> **[System requirements - Operations Manual](https://neo4j.com/docs/operations-manual/current/installation/requirements/)**
>
> An overview of the system requirements for running Neo4j in a production environment.

Alternatively if you are new to Neo4j you might consider starting with the Neo4j Desktop Application, as mentioned at the bottom of the URL above "Neo4j Desktop includes a Java Virtual Machine, _JVM_ , for convenience. All other versions of Neo4j require Java to be pre-installed."

When installing as a apt package the correct Java is installed as part of the dependencies. See [https://debian.neo4j.com/](https://debian.neo4j.com/) for details.

On a server this is the preferred way of installing.  
On a desktop the Neo4J Desktop environment is the easiest choice.
