Add content to Java roadmap

[kamranahmedse]

Java Roadmap has been made interactive, but it is missing content in some of the roadmap nodes. We need to fill the markdown files given here with a short intro to the topic mentioned in the markdown file and add some resources as per the guidelines here.

Note — You don't have to fill all the markdown files simultaneously. Feel free to create separate pull requests with batches of changes (e.g. fill up 15 content files in each PR).
