Chen Guoping commented on COLLECTIONS-742:
------------------------------------------
Hello Wesllhey Holanda,
When we call the CollectionUtils.get(Object object, int index) with index=0 and
the collection is null, maybe it's better to throw the
IllegalArgumentException("Unsupported object type: null") than with just
returning with nothing.
> Create new method in CollectionUtils to return first element if not null

> Reporter: Wesllhey Holanda

> When we try to get the first element into collection, we have to lead with
> null point exception. So with this method, when the collection is null or
> empty, the method will return null, and when not, the method will return the
> first element.
> In this way, the user don't need to write nothing to lead with null point
> exception.
