Subject [jira] [Commented] (LANG-784) Strange behavior on StringUtils.difference
Date Sat, 20 Apr 2013 08:53:16 GMT

    [ https://issues.apache.org/jira/browse/LANG-784?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13637160#comment-13637160
] 

Henri Yandell commented on LANG-784:
------------------------------------

I'm in favour of javadoc improvement. Something that notes that 'This means that "abc" - "ab"
is the empty String, not "c".' If we'd been redoing it, I'd probably make it work the other
way. Show the remainder of the first String and not the second String, but we're API bound
now.

> Hi,
> The behavior of the method StringUtils.difference () behaves in a non-intuitive (explain
in the javadoc).
> StringUtils.difference ("abc", "") returns "" as intuitively expected to be "abc".
> Is it possible to change this behavior ?
