Scala allows you to do this in a much cleaner way than the standard
StringAPI by leveraging the collections API (for which there is an implicit conversion from ajava.lang.Stringinto anIndexedSeq[Char]):The fantastic thing about the API of course, is that it preserves the type representation of the original “collection” (i.e.
Stringin this case)!
