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

jdavidb on 2008-04-09T20:57:18

In Perl:

@p = ('?') x 15;

In Java:

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

Nitpicking...

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. :)
