Converting lists of one element type to a list of another type

element, java, list

Solution

Java 8 way:

List<String> original = ...;
List<Wrapper> converted = original.stream().map(Wrapper::new).collect(Collectors.toList());

assuming `Wrapper` class has a constructor accepting a `String`.

Problem

I'm writing an adapter framework where I need to convert a list of objects from one class to another. I can iterate through the source list to do this as in Java: Best way of converting List<Integer> to List<String> However, I'm wondering if there is a way to do this on the fly when the target list is being iterated, so I don't have to iterate through the list twice.
