One of the features I like about Scala is the one line entity declaration. I'm working on a project with Java and I miss the one line declaration. Sure, I can use Intellij to generate boilerplate code but I personally do not feel it the same. With regards to your code, is there any reason you prefer straight sql statements than using a ORM? Hibernate maybe?. I know performance would be one but I'm interested to know in alternatives. Would you recommend java 16 for a project that would take 3 years to develop given that by that time code most likely be fully supported. Good post btw. Thanks.
