Fryderyk Wysocki commented on LANG-1032:
----------------------------------------
[~ggregory] this issue is 12+ years old, so I assumed that if this was not
needed, then someone whould have closed/rejected it by now. If it is neither
needed nor desired, then please consider having it closed. Otherwise, if it is
still wanted, then I'm happy to contribute the remaining overloads once the
approach is signed off.

> Key: LANG-1032
> URL: https://issues.apache.org/jira/browse/LANG-1032
> Project: Commons Lang
> Issue Type: New Feature
> Components: lang.*
> Affects Versions: 3.3.2
> Reporter: Ondra Žižka
> Priority: Major
> Fix For: Patch Needed, Discussion

>
> For performance reasons, it would be better to have a version of each join
> method which puts the intermediate results into a StringBuilder.
> I didn't look but believe that internally they use it anyway.
> So the method which returns String could be a wrapper for that.
> Thanks for considering.
