Combine two lists of same size (and different type) into list of domain objects using java streams

Question

I\'m having two lists of same size ids and results and I want to create new list with domain objects.

List ids = ...

Lis         


        

Answer 1

The equivalent of this way with Streams would be :

List<DomainObject> list = IntStream.range(0, ids.size())
                            .mapToObj(i -> new DomainObject(ids.get(i), results.get(i))) 
                            .collect(Collectors.toList());

Or take a look at Iterate two Java-8-Streams

Answer 2

I've found a way to do it using guava zip operator.

List<DomainObject> list = Streams.zip(ids.stream(), results.stream(), DomainObject::new)
                            .collect(Collectors.toList());
