public final class ArrayUtils extends Object
Operations on arrays, primitive arrays (like int[]) and primitive wrapper arrays (like Integer[]).
This class tries to handle null input gracefully. An exception will not be thrown for a null array
input. However, an Object array that contains a null element may throw an exception. Each method documents
its behavior.
