public Object[] toArray(Object[] a)
If the Set fits in the specified array with room to spare (i.e., the array has more elements than the Set), the element in the array immediately following the end of the Set is set to null. This is useful in determining the length of the Set only if the caller knows that the Set does not contain any null keys.)

a
- the array into which the elements of the Set are to
be stored, if it is big enough; otherwise, a new array
of the same runtime type is allocated for this purpose
ArrayStoreException
- if the runtime type of the specified
array is not a supertype of the runtime type of every
element in this Set of keys
