Calculate factorial of a number using Recursion

import java.util.Scanner;

public class FactorialOfNumber {

      static int factorial(int n) {

            if (n == 0)

                  return 1;

            else

                  return (n * factorial(n - 1));

      }

      public static void main(String args[]) {

            int i, fact = 1;

            //Input the number

            System.out.println("Enter a Number");

            Scanner sc= new Scanner(System.in);

            int number = sc.nextInt();

           

            fact = factorial(number);

            System.out.println("Factorial of " + number + " is: " + fact);

      }

}

Output:

Enter a Number

5

Factorial of 5 is: 120
