A command without context is not very useful. If anyone wants to run LanguageTool locally, I suggest reading the official documentation page: https://dev.languagetool.org/http-server

Their recommended process is :

1. Install fasttext (it's an official Debian package, but you have to compile it on Windows).

2. Download and uncompress the LanguageTool release.

3. Create a config file.

4. Launch the server with the java command (of course, a JRE must be installed).

5. Connect to the API, e.g. with the browser extension.

Running a ready-made docker image replaces steps 1-4 and removes the need to install Java globally. Some will prefer it this way.

We can go pretty low level in the docker option too.

1. Download a Linux installation image

2. Download a hypervisor

3. Install Linux on the virtual machine

4. Install docker in a virtual Linux machine

5. Launch LanguageTool container

6. Configure networking between the host and the container in the guest

7. Connect to the API, e.g. with the browser extension

Obviously I initially oversimplified by omitting the configuration step. But adding download step to inflate the complexity is not a fair play ;-)

I'd argue that running a platforn-native artifact is both simpler and easier than involving virtualization. Even if steps 1-4 are done by some magical tool like rancher or docker-desktop
