Given below is another program where the number whose factorial is to be calculated is taken as an input from the user and the result is displayed on the screen.

public class Factorial {
   public static void main(String[] args) {
       int n = 5;
       int result = factorial(n);
       System.out.println("The factorial of 5 is " + result);
   }
   public static int factorial(int n) {
       if (n == 0) {
          return 1;
       } 
       else {
          return n * factorial(n - 1);
       }
   }//end of factorial(int n)
}//end of class

Output:

The factorial of 5 is 125
