> Suppose x is a collection known to contain only strings. The following code can be used to dump the collection into a newly allocated array of String:
>      String[] y = x.toArray(new String[0]);
> Note that toArray(new Object[0]) is identical in function to toArray().

> Recommended and faster to use the zero-size-array format
