Java Hero:Streamโs Java theme needs operation chaining, and a 2.5M-element 800-op Java tool fits. Is the puzzle in the 'Stream Parallel' level (optimizing 45 parallel processing issues)? Does it processes 2.5 million elements via Java Streams, chains 800 operations (filter/map/reduce), and has a 'Stream Profiler' that measures 20+ processing time metrics?
