This seems like a reasonable approach. I'd expect tab to be trimmed for example.
Commons-Lang is a good source to consider when looking at naming.
Rather than re-using "trim", commons-lang uses "strip". So you have
strip(), stripLeft() and stripRight().
If you want to stick with "trim", how about trimAll() instead of
trimWhitespace(). Shorter and more obvious I think. Otherwise, I think
you'd need trimWhitespaceLeft() and trimWhitespaceRight() to match.
In line with these whitespace methods, I'd like to see isBlank()
added, could also be named isWhitespace(). The existing isEmpty()
method is fine, but a lot of the time user input validation routines
want to base their decision on "empty once trimmed". str.isBlank()
would be the same as str.trimAll().isEmpty() but without the object
Finally, a constant for EMPTY has always been missing from
java.lang.String. It would be great to add it.
