Answer 1

Learn Java. You don't need to know everything, but OOP and modularization-related parts like Generics, inheritance, and etc will be useful.

Learn to build an API. Including automated tests & documentation is nice, and an API website (can be easily automated with, for example, GitHub's GH-Pages) just for the docs is not the worst idea.

Build the API.

For easy, free, online hosting you can try Heroku, but of course there are limitations.
