Java 8: Formatting lambda with newlines and indentation

Question

What I would like to achieve with lambda indentation is the following:

Multi-line statement:

String[] ppl = new String[] { \"Karen (F)\", \"Kevin (M)         


        

Answer 1

I format single-line statement by adding empty comment "//" after functions.

List list = Arrays.stream(x) //
                           .filter((n) -> n % 2 == 0) //
                           .map((n) -> n * 4) //
                           .boxed() //
                           .collect(Collectors.toList());
