Subject new feature: coalesce operator / method
Date Fri, 30 Oct 2009 13:39:37 GMT
hi,

after writing an if (x != null) {o = ...} else if (y != null) {o = } ...
cascade, i just thought that we could use a coalesce operator in java as well....


until sun will support this i think this could be hosted somewhere in the commons.lang package:

Operators.coalesce(final Object... object);

this then would return the first non-null objecet from the given list/array.

alternatively this could also go on ObjectUtils. 

what do u think?
