Key and value implies a relationship between the two parts of the pair (the key somehow describes the value), which we cannot do (implementing Map.Entry is for convenience, not for any other reason). Either first/second or left/right are valid choices. At OpenGamma we use first/second but are able to change to left/right if this class is released. > I still do not like Pair as a name because a pair is: two identical, > similar, or corresponding things that are matched for use together: a pair > of gloves; a pair of earrings. > (http://dictionary.reference.com/browse/pair) > > We clearly break this common sense definition. I understand that from an English language POV, but Java devs all over know this as a pair. No other name will do I'm afraid.
