Secondary development Based on java

I’d like to do some secondary development for nextcloud by java. But I haven‘t found some demo or APIs and usage description for APIs. so, I need some suggestions from you. Regard sincerely.

Something like this?

Not everything seems to be up to date (https://github.com/nextcloud/documentation/issues/310), some apps also provide API stuff that might not be documented here.

I’ll move to the development section…

not really. I need RESTFUl API or demo based on java.

we don’t have that.

ok, thank you all the same.
