For loop

For loop

A simple example of using for loops to calculate factorial. Uses the built in int data type so only good to 13!

public class Factorial
{
 public static void main(String[] args)
 { final int NUM_FACTS = 100;
  for(int i = 0; i < NUM_FACTS; i++)
   System.out.println( i + "! is " + factorial(i));
 }
 
 public static int factorial(int n)
 { int result = 1;
  for(int i = 2; i <= n; i++)
   result *= i;
  return result;
 }
}
