Best way to fill a map using java steams

We have a map that we are filling in multiple calls from a list passed as a param:

  Map<String, Double> priceByID 

Which style is considered a cleaner code to fill our map? Why?

list.stream().map(e -> new AbstractMap.SimpleEntry<>(e.getId(), e.getPrice())).forEach(priceByID.entrySet()::add);

OR

 Map<String, Double> map = list.stream().collect(Collectors.toMap(e -> e.getId(), e -> e.getPrice()));
  priceByID.putAll(map);

list.stream().map(e -> new AbstractMap.SimpleEntry<>(e.getId(), e.getPrice())).forEach(priceByID.entrySet()::add);

> You are creating a stream of map entries, and the go over it and insert it. there's no real reason to do it, you creating tones of redundant objects

Map<String, Double> map = list.stream().collect(Collectors.toMap(e -> e.getId(), e -> e.getPrice()));
  priceByID.putAll(map);

> again, creating redundant map that will be removed afterwards, and also go over the items twice - once on the stream, and again on the putAll

you can use:

list.forEach(e -> priceByID.put(e.getId(), e.getPrice()))

or even:

for (?? entry : list) {
   priceByID.put(entry.getId(), entry.getPrice()));
} 

it will do the job just the same.
