Question

Change the factorial method to return a BigInteger. You can leave the parameter value alone (ie, the parameter will remain an integer). You'll need to modify the method to use

BigInteger objects and instance methods.

Hint: remember that you can easily form Strings from numerical values by concatenating the numerical value with the empty String "". For

Example:

String s = 5 + "";

•What happens when you rerun your loop in main? Do you get the correct answers?

import java.math.BigInteger;

public class Lab10 {

   public static int factorial(int n) {
       int result = 1;
       for(int i = 1; i <= n; i++) {
               result *= i;
       }
       return result;
   }

   public static void main(String[] args) {
       for(int i = 1; i < 31; i++) {
           System.out.println(i + "\t" + factorial(i));
          
           }

   }

}
