Thanks CEHJ. &nbsp;My final result needed to be the primitive type double, not Double. So, I ended up doing away with the ArrayList entirely (which I discovered can't have primitives as a item type), and just used an array of doubles. &nbsp;I'm so used to using ArrayList, &nbsp;that I wasn't thinking outside the box. &nbsp;Thanks again. &nbsp;Mark<br />
<br />
P.S. Also, fortunately I knew how many elements I needed ahead of time (and that number doesn't change), so the basic array of doubles worked just fine.

I am getting a type mismatch error. &nbsp;My List (named list) is specified as &lt;Double&gt; <br />
I am attempting to convert Double to double.<br />
<br />
But, somehow it thinks my List is of type Object (instead of Double).<br />
What am I missing?<br />
<br />
Thanks, Mark<br />

Experts,

I am getting a type mismatch error.  My List (named list) is specified as <Double> 
I am attempting to convert Double to double.

But, somehow it thinks my List is of type Object (instead of Double).
What am I missing?

Thanks, Mark

type mismatch (Object[] to double[]

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
