Neat! It&#x27;s been a while since I wrote Java code. Java8 lambda syntax looks quite reasonable. I&#x27;d recommend the author to make &quot;Getting Started&quot; section a bit more detailed. One of the gripes I&#x27;ve heard is that Java setup and build are non trivial for inexperienced engineers. So maybe some script&#x2F;screenshot HOWTOs or adding a Dockerfile?
