They also have a perpetual license. If you cancel after the first year, you can keep using the version that was current 12 months ago.

But the one thing missing in Java is anything like LINQ. I don’t mean the syntax I am referring to the idea of LINQ -> expression trees -> third party providers that translate LINQ to another language (sql, Mongo Query, etc.).

I do miss LINQ though. The Java options are all clunkier because the type system isn't nearly as flexible

  Person.Get(p => (p.Age > 65 && p.Sex == "M") || (p.Age > 63 && p.Sex == "F"))

  public List<Person> Get(Expression<Func<Person,bool>> expression)

You get full compile time checking and IDE supported autocomplete.

The Java code "looks" like they do the same because they generate code to simulate method references instead. It's pretty clever and Javas code generation support for Annotation Processors is excellent and makes it possible to do this in a cross-ide cross-build-system way

LINQ and JOOQ/QueryDSL all work on plain data objects with fields. But with Java you do it on a pseudo object generated from your existing classes

All of these years I've been beating up on Java for lack of something akin to LINQ. I guess I'll have to find something else to complain about.....
