Hi, In my opinion it would be nice if all the methods do the same for the same null or empty string input and would be consistent, but... I won't change the existing API in the current 3.x version. So I think we should fix them only in 4.0. However, we should fix it in the Strings class, before it is released to start the unifying.
For the unified behavior, I think either - null for null and "" for "" - "" for null or "" Regards, David Gary Gregory <garydgreg...@gmail.com> ezt írta (időpont: 2024. dec. 4., Sze, 12:46): > Hi all, > > The StringUtils methods return a mix of null and "" for each method on null > input.
