OOP and FP
summary
Compares idiomatic Java 7 OOP style with Java 8’s functional style using concrete examples: string joining with map/reduce to avoid mutable StringBuilder, grouping with Collectors, finding min/max via a single reduce, and using lazy streams to read large logs with limit that prevents loading the whole file. Shows parallelism via parallel streams (noting danger because they use the ForkJoinPool by default), points out Java 8 has no built‑in sliding window, and demonstrates asynchronous composition using CompletableFuture instead of nested callbacks.
