checked for (deep) equality. If two corresponding elements are arrays of
a primitive type then the appropriate Arrays.equals method
is used to determine their equality. Otherwise for two
Object arrays deepEquals is called
recursively.
This method should not be used if either of the arrays, or any arrays

array1 - the first Object array
Parameters:
array2 - the second Object array true when the arrays have the same length and the elements ateach index in the two arrays are equal, false otherwise |
| deepHashCode | | public static int deepHashCode(Object[] array)(Code) | | Returns the 'deep' hash code for the given array. This means that if this

itself.
If Arrays.deepEquals(...) returns true for two arrays then their deep
hash codes will also be equal.
If the array is null the return value will be 0.
Parameters:
array - the array to return the hash code for the hash code for array |
| deepToString | | public static String deepToString(Object[] array)(Code) | |
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 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
String.valueOf(Object) method.
Parameters:
array - The Object array to convert. The String representation of array.

Parameters:
array - the array to return the hash code for the hash code for array |
| hashCode | | public static int hashCode(Object[] array)(Code) | | Returns the hash code for the given array. If this array contains other
arrays, their contents will not be recursively searched so this method
should be used if the array is likely to contain a reference to itself.
If Arrays.equals(...) returns true for two arrays then their hash codes
will also be equal.
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 will be 0.
Parameters:
array - the array to return the hash code for the hash code for array |
