converting objects in a vector to array of primitives

[kmcculler]

Situation: I've got a Vector full of Double (object) numbers that I need to pass to a charting module witch only accepts an array of primitive doubles.
Question: Is there any better way to create a double[] from my Vector than to move through each element of it and build an array step by step? Kris McCuller

Nope, no easier way.

Hi,

I do not think there is anything elegant.

May be you should reconsider things from scratch
and whenever you populate a vector with Double wrappers
just populate an array of primitive doubles.
Keep in mind that arrays in Java can be created dynamically
and many standard classes, Vector including, use this
approach.
