Module 10: Functional Programming and Streams
Terminal Operations & Collectors
Leverage reduce, collect, matchers, and summary statistics for aggregated results.
Use collect(Collectors.toList()) or specialized collectors like groupingBy, partitioningBy, summarizingInt.
Reduce accumulates values manually; combine identity, accumulator, and combiner carefully.
Match operations (anyMatch, allMatch) allow short-circuiting; findFirst/findAny extract elements efficiently.
