You made a claim (which has no link to the other thread) which is questioned by Julian and I would like to have numbers which may support your claim. That's all. If you don't have numbers, don't claim performance gains.... > >> The point is whether it is important for the operation to have a "Hash" >> map or a Map which happens to be hashed.... > > What's the point in declaring the field as Map if I want it to be a HashMap? Because the your code using the map does not care. It is just one single location which cares: the point where you create the object. So if your code just uses a map, why declare it a HashMap -- you might later decide to use a GrokMap or a StupidMap instead of HashMap and you don't want to change your code except for the constructor, do you ? (And yes, this is also different from the main discussion thread) Regards Felix
