answer convert hashset to array

convert hashset to array

Comment

//	First of all, you shouldn't use raw types.
//	Use :
	Set<Integer> set = new HashSet<>();
	set.add(4);
	set.add(1);
//	Then convert to array :
	Integer[] arr = x.toArray(new Integer[set.size()]);
//	Using x.toArray() would give you an Object[].
