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.
array1 | the first Object array. |
---|---|
array2 | the second Object array. |
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.
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 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.

Object[]
passed, such that if the array contains other arrays,
the String
representation of those arrays is generated as well.
If any of the elements are primitive arrays, the generation is delegated
to the other toString
methods in this class. 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 valueOf(Object)
method.
