Java: Get first item from a collection

Question

If I have a collection, such as Collection strs, how can I get the first item out? I could just call an Iterator, take its first

Answer 1

You could do this:

String strz[] = strs.toArray(String[strs.size()]);
String theFirstOne = strz[0];

The javadoc for Collection gives the following caveat wrt ordering of the elements of the array:

If this collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.
