Is there a more concise way to write this method using Lambda Expressions?

Question

I'm sorting an array of "Albums" by the output of their method getAlbumArtist(), using a custom comparator class, AlphaNumComparator, which has a method compare, which compares two strings.

I have the following code, which works:

AlphanumComparator comparator = new AlphanumComparator ( CaseHandling.CASE_INSENSITIVE );

Arrays.sort( albumArray, ( Album a, Album b ) -> {
    return comparator.compare( a.getAlbumArtist(), b.getAlbumArtist() );
});

This seems like the sort of code that could be simplified/made more clear with some of the new langauge features in Java, but I can't quite make the pieces fit. Is it possible, or is it about as consice as it gets?

Answer 1

I suggest you to use

    Arrays.sort(albumArray, Comparator.comparing(Album::getAlbumArtist, comparator));

Answer 2

Assume the albumArray is a list, you can do this

albumArray.sort(Comparator.comparing(Album::getAlbumArtist, String.CASE_INSENSITIVE_ORDER));

else you can do this

Arrays.sort(albumArray, Comparator.comparing(Album::getAlbumArtist, String.CASE_INSENSITIVE_ORDER));
