Processes a 235,000-word Webster list to print the 10 longest words (five of length 24, five of 23) using Files.lines, try-with-resources, Java 8 streams, lambdas, method references, Comparator.comparingInt.reversed, groupingBy and counting collectors, and Optional.max. Demonstrates Java 11 HTTP Client plus Jackson to fetch astronaut data, then maps into records + sealed interfaces + pattern-matching for switch to return success/failure results. Code and tests (Mockito, WireMock) live in the GitHub repo and currently target Java 20.
