Java Hero:Collection’s Java theme needs performance optimization, and a 2M-element 70-performance Java tool fits. Is the puzzle in the 'Collection Choice' level (selecting 45 optimal collections)? Does it manipulates 2 million elements via List/Set/Map, optimizes 70 performances (hashcode/iteration), and has a 'Collection Profiler' that measures 20+ operation times?
