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

["Henri Yandell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LANG-470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12729549#action_12729549 ] 

Henri Yandell commented on LANG-470:
------------------------------------

Thanks for the patch Hasan. 

The patch has array1 and array2 backwards I think. It should be array2 in array1, rather than array1 in array2. 

Need to decide what containsAll( array, null ) would mean. Is that a true? If it is, what does containsAll( null, null ) mean?

Also need to add some tests.

> The ArrayUtils class contains several "contains" methods.
> It could be usefull to add the corresponding containsAll(Object[] array1, Object[] array2) methods (and corresponding for primitive types).
