Benedikt Ritter commented on COLLECTIONS-430:
---------------------------------------------
To be honest, I don't see why it is more tedious to write {{new
DualHashBidiMap<String, String>()}} instead of {{MapUtils.newHashBidiMap()}}.
It spares you 12 characters. Factory methods make sense when several
constructors would have the same number of parameters of even the same
signatures. In this case a factory method does not add much, IMHO. Beside that,
people are used to use the default constructor when creating collections (and
maps), because this is how the java collections framework works.

> corresponding Utils classes

>
> It is quite tedious to write code like this:
> {noformat}
> BidiMap<String, String> map = new DualHashBidiMap<String, String>();
> {noformat}
> a more convenient way would be to take advantage from type inference like
> this:
> {noformat}
> BidiMap<String, String> map = MapUtils.newHashBidiMap();
> {noformat}
> This would apply basically for all data structures that are available in CC
> atm.
