> Add Overloading Methods To EnumUtils
> ------------------------------------

> Key: LANG-1495
> URL: https://issues.apache.org/jira/browse/LANG-1495
> Project: Commons Lang
> Issue Type: Improvement
> Reporter: Cheong Voon Leong
> Priority: Trivial
>
> I would like to add 2 overloading methods to EnumUtils, getEnum and
> getEnumIgnoreCase.
> Instead of returning null, if not found. In my opinion I think allowing user
> to set a default result is a better approach or return an Optional.
