Description: Modern code examples were still using System.out.println — replaced with IO.println / IO::println across all affected slugs, keeping oldCode blocks unchanged. Changes 10 YAML content files updated — only the modernCode field in each: language/pattern-matching-instanceof, record-patterns, private-interface-methods, default-interface-methods collections/reverse-list-iteration concurrency/virtual-threads, process-api, completablefuture-chaining streams/stream-iterate-predicate strings/string-lines Example modernCode: |- if (obj instanceof Point(int x, int y)) { - System.out.println(x + y); + IO.println(x + y); } Method references updated consistently: -).forEach(System.out::println); +).forEach(IO::println); Files already using IO.println (compact-source-files, io-class-console-io) were left untouched.
