Returns an array containing all of the elements in this queue, in
proper sequence.
<p>The returned array will be "safe" in that no references to it are
maintained by this queue. (In other words, this method must allocate
a new array). The caller is thus free to modify the returned array.
<p>This method acts as bridge between array-based and collection-based
APIs.
