Michael Bazos commented on LANG-1030:
-------------------------------------
I think you are correct, if we are going to add something in we should support
same and sameIgnoreCase. That would be the proper fix.
defaultIfEmpty if one of the strings is empty I would expect the default value.
Maybe defaultIfEmpty isn't a good name. defaultIfDifferent would probably be
more appropriate.
What do you think?
> StringUtils.same opposite method to StringUtils.differ
> ------------------------------------------------------
>
> Key: LANG-1030
> URL: https://issues.apache.org/jira/browse/LANG-1030
> Project: Commons Lang
> Issue Type: Improvement
> Affects Versions: 3.3.2
> Reporter: Michael Bazos
> Priority: Trivial
> Labels: StringUtils
> Fix For: Review Patch, Discussion
>
>
> This is pretty easy to do but I have seen this come up and was surprised to
> find that StringUtils didn't have a utility method.
> The difference() method is described as doing the following:
> Compares two Strings, and returns the portion where they differ.
> What I am proposing is essentially the opposite of the difference method
> called same(). This method would compare two String and return a new String
> when they are the same.
> This is essentially the implementation:
> {code:java}
> public static String same(String str1, String str2) {
> if (str1 != null && StringUtils.equalsIgnoreCase(str1, str2)) {
> return new String(str1);
> }
> return null;
> }
> {code}
> {code:java}
> StringUtils.same(null, null) = null
> StringUtils.same("", "") = "";
> StringUtils.same("123", "") = null
> StringUtils.same("123", "123") = "123";
> {code}
> If there is already a way to do this using the apache lang library please
> point me in the right direction. Otherwise I would be more than happy to do
> the testing, coding and documentation for this.
