@Mitchell, many people have solved it, just not many commented here. We don't want users to paste solutions or long code samples here, but you can link to your most recent submission instead by clicking on "Load Link" below the comment form.

Will the answer that was given run forever since the condition is less than or equal to a.?
-
Bernard, it will stop when 'i' in the for statement increments up to the same number as the 'a'.

have to pay already?? you have failed this community

int kq=1;
for(int i=a;i>0;i=i-1){
kq=kq*i;
}
return kq; -
You can solve this with recursion.
public static int doStuff(int a){
if (a==0 || a==1) return 1;
return doStuff(a-1)*a;
} -
I just gave 2 as the initial value of the variable i so I think my code will just jump the first useless iteration: 1*1.
my code -
import java.util.Scanner;
public class Factorial {
public static void main(String[] args){Scanner input = new Scanner (System.in); System.out.print("Enter a number to calculate: ");int num=input.nextInt(); int result=1; for (int i=1; i<=num; i++){ result = result*i; } System.out.println(result); }}

int b = a;
while(a!=1)
{
b = b*(a-1);
a -= 1;
}
return b; -
