Emmanuel Bourg commented on COLLECTIONS-505:
--------------------------------------------
Or soon using Java 8:
{code}List<Integer> result =
list.stream().distinct().collect(Collectors.toList());{code}
> Removing duplicates from a collection

> Key: COLLECTIONS-505
> URL: https://issues.apache.org/jira/browse/COLLECTIONS-505
> Project: Commons Collections
> Issue Type: New Feature
> Components: Collection, List
> Affects Versions: 4.0
> Reporter: Palvali Teja Burugu
> Priority: Minor
>
> Remove the duplicate elements from the given collection. Generally, to
> implement this, the list would be copied to a set and back to list, which
> removes all the duplicate elements. A utility method for this would be a
> good-to-have feature in the CommonsCollection.
