Hi, members of the core-libs developers of OpenJDK. I think Java needs a Strings class similar to the java.util.Objects class of Java 16 to be used in method arguments, return types and Stream filters.
I have coded it myself here based on the Objects implementation of Java 16 (please have a look): https://github.com/Aliuken/Java-Strings/blob/main/Strings.java In fact, I think it would be useful also adding annotations for method arguments and return types such as: - @NonNull - @NonNullElse(defaultValue) - @NonNullElseGet(class::supplierMethod) - @NonNullNorEmpty - @NonNullNorEmptyElse(defaultValue) - @NonNullNorEmptyElseGet(class::supplierMethod) With that kind of annotations, you could assume thinks like: - an argument or return type cannot have value null, but an Exception - an argument or return type cannot have value null, but a default value What do you think? Waiting for your response. PS: I am sending this email repeated. I have sended it yesterday with my other email account (alber8...@gmail.com), but I wasn't a member of this mailing list. Now I have become a member with this other email account. Regards, Alberto Otero Rodríguez.
