I'm working on playing nim, where the person who takes the last object wins. My program is currently working, but it terminates after I only take one bunch of stones (You can take up to 3 at a time), no matter what the pile size is. Is there a way that I can recall the public static int computerMove(int nStones) method so that the game just doesn't terminate after one turn? I've tried a few ways, but they obviously haven't worked.

```
import java.util.Scanner;
import java.util.Random;
public class NIM
{
static Random randomGenerator = new Random();
static int nStones = randomGenerator.nextInt(10);
public static int computerStones;
public static int newNStones;
/*
* Returns the correct number of stones to take
* (according to the winning strategy) when nStones
* remain in the pile; if such a move is not possible,
* returns a random number of stones to take.
* Precondition: nStones > 0
*/
public static int computerMove(int nStones)
{
Random stones = new Random();
int random = stones.nextInt(3);
int randomStones = random + 1;
if ((nStones % 3 == 0 || nStones % 4 == 1) && nStones !=0)
{
computerStones = nStones - 3;
System.out.println("After the computer's move, there are" + " " + computerStones + " " + "left in the pile." );
return 3;
