| 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.

Constructor Detailpublic ArrayUtils() ArrayUtils instances should NOT be constructed in standard programming. Instead, the class should be used as ArrayUtils.clone (new int[] {2}). This constructor is public to permit tools that require a JavaBean instance to operate. Method Detailpublic static java.lang.String toString(java.lang.Object array) Outputs an array as a String, treating null as an empty array.
