However, it might make more sense to provide a method to collapse all
whitespace to a single space (should probably also trim leading/trailing
whitespace). Do that to both strings and then compare them.
I think that would be more generally useful than an equals method, as it would
allow both case-sensitive and insensitive natching as well as potentially
detecting the first difference etc.
There could also be a method to remove all whitespace.
That would ignore word-boundaries in comparisons, but would have other uses.

We have this already:
StringUtils.normalizeSpace();
StringUtils.deleteWhitespace();

> Currently, no java uitility package offers a method to compare two strings
> which differ only in format & white spaces for equality. The common scenario
> when we need such a method would be (a) when one needs to perform equality
> check between two narrative fields in a SWIFT message or (b) to compare a
> paragrapgh retreived from different files.
> Please advise on how i can share the code for this new method. thank you
