Committed revision 594409.
Slight modification to the patch in that I removed a Math.max from the loop by
starting at 0 and not -1 for the smallest value.
> Shouldn't Commons Lang's StringUtils have a "common" string method?
> -------------------------------------------------------------------
>
> Key: LANG-269
> URL: https://issues.apache.org/jira/browse/LANG-269
> Project: Commons Lang
> Issue Type: New Feature
> Environment: generic
> Reporter: Michael Dang
> Fix For: 2.4
>
> Attachments: StringUtils.patch, v2_StringUtils.java.patch,
> v2_StringUtilsTest.java.patch
>
>
> A method which accepts a string array and returns a string which is the
> common portion of all the strings starting from the left, or more general
> form of that.
> This is very common operation. For example, one may want to find the common
> directory of a set of path strings.
> passing in:
> "/foo/f1.txt"
> "/foo/moo/f2.txt"
> "/foo/moo/f3.txt"
> should returns "/foo/"
> It is tedious to implement this in every project. And I think Commons Lang
> StringUtils should have some methods to help in this.
