[FIXED] How can I do this ForEach using lambda?

Issue

I have this foreach that parses some class to another:

public static List<MyClassParsed> getMyParsed(List<MyClassResponse> responses) {

    List<MyClassParsed> parses = new ArrayList<>();

    for (MyClassResponse response : responses) {

        var parse = MyClassParsed.builder()
                .id(response.getId())
                .name(response.getName())
                .build();

        parses.add(parse);
    }

    return detalhes;
}

I mean, can I do this using something like responses.stream().foreach(...) ?

Solution

You're transforming a list to a list of objects derived from elements of that list, so map looks like a good solution.

public static List<MyClassParsed> getMyParsed(List<MyClassResponse> responses) {
    return responses.stream()
                    .map(r -> 
                         MyClassParsed
                             .builder()
                             .id(r.getId())
                             .name(r.getName())
                             .build())
                    .collect(Collectors.toList());
}
