static float[][] |
clone(float[][] array)
Clones a two dimensional array of floats.
|
static int |
compareVersionArrays(Comparable[] a1,
Comparable[] a2)
Compares the initial elements of two arrays.
|
static boolean |
equal(float[][] array1,
float[][] array2)
Tests two float arrays for equality.
|
static boolean |
equalReferencesInArrays(Object[] array1,
Object[] array2)
Returns
true if all the references in array1
are equal to all the references in array2 (two
null references are considered equal for this test). |
static boolean |
hasDuplicateItems(Object[] array)
Returns
true if any two items in the array are equal to
one another. |
