How to get List of List instead of List of Array from a stream?

Question

I want to got a List of List instead of List of Array in the below code:

List<String[]> list = org.simpleflatmapper.csv.CsvParser.reader(in).stream().collect(Collectors.toList());

How can we got List<List<String>> list = ... ?

Answer 1

you need to map String[] to List

List<List<String>> list = org.simpleflatmapper.csv.CsvParser.reader(in).stream()
.map(Arrays::asList)
.collect(Collectors.toList());

Answer 2

org.simpleflatmapper.csv.CsvParser.reader(in).stream()
          .map(Arrays::asList)
          .collect(Collectors.toList());
