Shortcut for list->stream->map()->list

Question

I often convert lists like that

myList.stream().map(el -> el.name).collect(Collectors.toList())

is there any shorter version for this?

Answer 1

You could statically import Collectors.* and then use the mapping(Function, Collector) method, like this:

myList.stream().collect(mapping(T::getName, toList()));

Where T::getName is a method reference and T is the Type of the elements in the List. Using this is more readable and also almost identical to writing: el -> el.name
