Adding a list of user-inputted doubles to an Array
<p>So my program, when instantiated asks the user how many "items" they want.  My program then creates two arrays, one for the "item name" and one for the "item price".  I use a loop to let the user input each item name and item price in their respective arrays, however I'm lost with the item price array.  To use my loop, I need to utilize the "itemprice.length" element but I can't do that when I'm not working with Strings.  </p>

<p>After the user inputs the "prices" of each item, I need to apply a multiplier to each array item and output it.  So I want to, for example, have 3 items in the array: 1.20, 1.30, 1.40, and then I want the program to ask me for the "sales tax" of which I can enter 0.08 and it will then multiply 0.08 to each item and output a total. </p>

<p>Is there a way that I can make my program work so it allows the user to enter, let's say, 5 items and their prices and am I going about it the right way?  Any way of doing this easier?  Thanks!</p>
