how to rotate value in array java code example

Example 1: array rotation program in java

//Rotating array left 
//d = number of rotations
static void rotLeft(int[] a, int d)
{
    //using secondary array of  same size 
	int [] n = new int[a.length];
    //saving element into array n[] according to newlocation of rotations(d)
	for(int i = 0; i < a.length; i++)
	{
		int newlocation = (i+(a.length - d))% a.length;
		n[newlocation] = a[i];
	}
	//printing new rotated array
	for(int i = 0; i < a.length; i++)
	{
		System.out.print(n[i]+ " ");
	}
}

Example 2: 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);
	}
}
