hashCode

public static int hashCode(float[] array)
Returns a hash code based on the contents of the given array. For any two float arrays a and b, if Arrays.equals(a, b) returns true, it means that the return value of Arrays.hashCode(a) equals Arrays.hashCode(b). The value returned by this method is the same value as the List.hashCode()} method which is invoked on a List} containing a sequence of Float} instances representing the elements of array in the same order. 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

hashCode

public static int hashCode(double[] array)
Returns a hash code based on the contents of the given array. For any two double arrays a and b, if Arrays.equals(a, b) returns true, it means that the return value of Arrays.hashCode(a) equals Arrays.hashCode(b). The value returned by this method is the same value as the List.hashCode()} method which is invoked on a List} containing a sequence of Double} instances representing the elements of array in the same order. 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

hashCode

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

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()} method 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:

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 incertitude.

Parameters:
array1 - the first Object array
array2 - the second Object array
Returns:
true when the arrays have the same length and the elements at each index in the two arrays are equal, false otherwise

deepToString

public static String deepToString(Object[] array)

Creates a "deep" String representation of the Object[] passed, such that if the array contains other arrays, the String representation of those arrays is generated as well.

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.
