If you'd really like to make a Java equivalent of any specific algorithm you can start even without a book.
I guess that anybody not versed in Ruby would first have to understand a lot of Ruby details first. The author mentions other efforts relatively similar to his, in other languages, like http://gitlet.maryrosecook.com/docs/gitlet.html which is node JavaScript.
I know the author has very graciously provided the source code. I would just like to read through the book to know what kind of reasoning exists behind each of the parts in the author's own words.

The book's code is implemented in Ruby, and the source is here, according to the author, around 6000 lines (haven't checked myself).
