Why doesn't my code enter my loop?

Question

I want to loop through the items in a collection but it doesn't ever get into the loop.  Any hints?

Answer 1

Sure, here is a hint.  Make sure you are using the proper method to determine the size or length of the collection type being iterated (JavaScript array, Java arrays, or java.util collection classes etc.).  For example: size(), length(), length apply to different types.

Please add example code that shows how size(), length(), and length are related to types being iterated.
