| Description |
The ToArray method builds a new Array, and fills it with all the element values from the current Queue.
Just like CopyTo, ToArray performs a shallow copy. When the current Queue holds reference (non primitive) data types, the target array element values still refer to the same objects that current queue elements refer to. This is what is referred to as a shallow copy. A deep copy would create new versions of the referred objects.
