Java Hero:Generics’s Java theme needs bounded wildcards, and a 210-class 1.3k-wildcard Java tool fits. Is the puzzle in the 'Bounded Wildcard' level (resolving 75 issues with /)? Does it uses bounded wildcards for type safety, and has a 'Wildcard Tool' that validates 20+ wildcard bounds per generic method?
