For example, the following method returns an array that is the reversal of another array − Example public static int[] reverse(int[] list) { int[] result = new int[list.length]; for (int i = 0, j = result.length - 1; i < list.length; i++, j--) { result[j] = list[i]; } return result; } + Arrays.binarySearch(Arr, 1, 3, ele)); There is again the possibility to call the method on a subset of the array. Live Demo. Compare this to the List version: You can use a List to hold the values and invoke the toArray method if needed Passing Two Dimensional Arrays to Methods.
