Gilles commented on MATH-1041:
------------------------------

I've already committed some changes, one at a time. Sorry if I've been to fast. 
:)
Could you please update your working copy, and provide further changes in 
separate patches?
E.g. it would be nice to have one patch for the comparator code and unit tests.


> Add Pair factory method, toString(), Comparator

>             Project: Commons Math
>          Issue Type: Improvement
>    Affects Versions: 3.2
>            Reporter: Sean Owen
>            Priority: Minor

> I use Commons Math heavily, and have adopted its Pair class for the cases 
> where I need, well, a pair of things.
> The attached patch adds three small improvements to the Pair class:
> - toString() method
> - factory method ".create()" to avoid duplicating generic types on instance 
> creation
> - a Comparator
> Tests are included. I won't feel offended if this is rejected or modified but 
> just wanted to supply  the suggestion.
