java rotation of the array code example

Example: how to rotate array java recursively

private static void rotateLeftOne(char[] arr, int length, int num) {
	int pos = length - num;
	if (pos != length - 1)
	{
		char temp = arr[pos];
		arr[pos] = arr[pos + 1];
		arr[pos + 1] = temp;
		rotateLeftOne(arr, length, num - 1);
	}
}
