Pascal's Triangle

[roher4]

I can't find the error's in this program. I had to create these methods and must use them. It's for my high school class and I've cut 19 errors to one.

import java.util.Scanner;

public class Pascal{

public static void main(String[] args)
{
	Scanner input= new Scanner(System.in);
   int rows = getRows();
   while (rows != 0){
      printTriangle(rows);
      rows = getRows();
   }
} 

public static long factorial(long n)
{
	//A number that is leading up to the specified number
	for (int i=2,k=1; i<=n; i++){
	k*=i;
	return k;
	}
	return 1;
}
public static int getRows(){
	Scanner input= new Scanner(System.in);
	
	int rows=5;
	System.out.println("Please enter the number of rows:");
	rows = input.nextInt();
	return (rows);
}

public static long nCr(long n, long r){
	return factorial(n)/factorial(r)*(factorial (n-r));
}

public static void printTriangle(int r){
	for (int i=1;i<=r;i++)
	{
		for(int j=1;j<=i; j++)
		{
			System.out.println(nCr(i-1,j-1));
		}
		
		System.out.println("");
	  }

	}

}

what did the compiler spit out, what type of error?

Arithmetic exception..divide by zero?
