org.apache.hudi.common.util.collection.ArrayUtils

public 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 behaviour.
