I am using version 1.5.9 and it uses Java 7 style syntax for all the solutions.
I am wondering if the new edition has solutions with Java 8 syntax?
The github repo also used Java 7 syntax.
Please check http://epijudge.com/ for the latest solution as we are moving to this testing framework for our readers.
Which version does the latest copy of the book has? Would it have Java 8 style declaration(for some common ones like comparators (x,y) -> x-y)
The latest copy of the book shall have that as far as I know. We are moving to Java 9 syntax in the solutions recently (e.g., List.of).
