      public static int hashCode(Object[] array)

      Returns a hash code based on the contents of the given array. If the array contains other arrays as its elements, the hash code is based on their identities not their contents. So it is acceptable to invoke this method on an array that contains itself as an element, either directly or indirectly.

    • deepHashCode

      public static int deepHashCode(Object[] array)

      Returns a hash code based on the "deep contents" of the given array. If the array contains other arrays as its elements, the hash code is based on their contents not their identities. So it is not acceptable to invoke this method on an array that contains itself as an element, either directly or indirectly.

      For any two arrays a and b, if Arrays.deepEquals(a, b) returns true, it means that the return value of Arrays.deepHashCode(a) equals Arrays.deepHashCode(b).

      The computation of the value returned by this method is similar to that of the value returned by List#hashCode()} invoked on a List} containing a sequence of instances representing the elements of array in the same order. The difference is: If an element e of array is itself an array, its hash code is computed by calling the appropriate overloading of Arrays.hashCode(e) if e is an array of a primitive type, or by calling Arrays.deepHashCode(e) recursively if e is an array of a reference type. The value returned by this method is the same value as the method Arrays.asList(array).hashCode(). If the array is null, the return value is 0.

      Parameters
      • array: the array whose hash code to compute.
      Returns

      the hash code for array.

    • deepEquals

      public static boolean deepEquals(Object[] array1, Object[] array2)

      Returns true if the two given arrays are deeply equal to one another. Unlike the method equals(Object[] array1, Object[] array2), this method is appropriate for use for nested arrays of arbitrary depth.

      Two array references are considered deeply equal if they are both null, or if they refer to arrays that have the same length and the elements at each index in the two arrays are equal.

      Two null elements element1 and element2 are possibly deeply equal if any of the following conditions satisfied:

      element1 and element2 are both arrays of object reference types, and Arrays.deepEquals(element1, element2) would return true.

      element1 and element2 are arrays of the same primitive type, and the appropriate overloading of Arrays.equals(element1, element2) would return true.

      element1 == element2

      element1.equals(element2) would return true.

      Note that this definition permits null elements at any depth.

      If either of the given arrays contain themselves as elements, the behavior of this method is uncertain.

      Parameters

      • array1: the first Object array.

      • array2: the second Object array.

      Returns
      Returns:
      true if both arrays are null or if the arrays have the same length and the elements at each index in the two arrays are equal according to equals(), false otherwise.

If any element contains a reference to the original array, then it will be represented as "[...]". If an element is an Object[], then its representation is generated by a recursive call to this method. All other elements are converted via the String#valueOf(Object) method.
