How to swap keys and values in a Map elegantly

Question

I already know how to do it the hard way and got it working - iterating over entries and swapping \"manually\". But i wonder if, like so many tasks, this one can be solved

Answer 1

Map map = new HashMap<>();
Map swapped = map.entrySet().stream().collect(Collectors.toMap(Map.Entry::getValue, Map.Entry::getKey));
