[jira] [Commented] (LANG-470) Add containsAll methods to ArrayUtils

["Matt Benson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13065697#comment-13065697 ] 

Matt Benson commented on LANG-470:
----------------------------------

Just for containsAll... this is a Collection method, to be precise, so it is still pretty short, even with the null checks:

{{Arrays.asList(ArrayUtils.nullToEmpty(array1)).containsAll(Arrays.asList(ArrayUtils.nullToEmpty(array2)))}}

--even shorter with static imports.  On the whole the commons team doesn't seem to favor this, myself included.
