No Hate on Java 8, But 9–14 Reign Supreme
summary
Modernizes a Java 8 Selenium test using concrete Java 9–14 features: replace repetitive declarations with var (local type inference) and rules for use; replace loop + list population with Stream.map and collectors; use takeWhile/dropWhile (example list of 11 accounts yields 3 then 8) after sorting; use switch expressions to assign values without fall-through; show preview records (final fields, accessor names without get) and text blocks for embedded JSON, noting previews lack full library support so avoid in production yet.
