Thread: Factorial of 1-20

I have to display the factorial's of numbers 1 - 20. I believe my code should work, but i keep getting the error:


FactorialTest.java:6: cannot find symbol
symbol : method factorial(int)
location: class FactorialTest
System.out.println( factorial( x ) );;
^(pointing under the "f" in "factorial")

Any help on what's causing my error, and how to fix it, would be greatly appreciated. Thank's in advance.

public class Factorial
{
	public static long factorial(int n)
	{
		if(n<=1)
			return 1;
		else
			return n*factorial(n-1);
	}
}

public class FactorialTest
{
	public static void main(String[] args)
	{		
		for( int x=1; x<=20; x++)
			System.out.println( factorial( x ) );;
	}
}

Im just think about this and could be wrong but try putting the int x out of the for loop and use and int i in the for loop instead: like this

int x;
for(int i; i<20;i++)
{
      System.out.println(factor(x));
}

That might work
