Hi, I have a client calling code like this:



Requirement - Return a single Iterator<String> that chains together the array of Iterator<String>s in the order that
they are provided, but skips {@code null} values.

actual method implmentation of iterateStrings



How do I copy the stringIterators to a LIst. I thought of doing that, then in a for loop, removing the null values and returning the Iterator<String>..Please advice.
