Initialization of an ArrayList in one line

I usually prefer new ArrayList(List.of(...)) on Java 9+ since it's clean, concise, and gives you a modifiable list. For older Java versions, red humana exito Arrays.asList() wrapped in an ArrayList is still a solid choice. I'd avoid double-brace initialization in production code because of the anonymous inner class…
