Java gem of the day: nCopies() ('x' in Java)

[ #36115 ]

In Perl:

@p = ('?') x 15;

In Java:

List<String> p = Collections.nCopies(15, '?');

  • To be equivalent code, shouldn't that second one be this?

    List<String> p = Collections.nCopies(15, '?');
    • That's not nitpicking! That's helpfully correcting my typo! Thank you!!

    • Actually to be "equivalent" I should probably also declare @p with my. :)
