Java program to find factorial of a number without using Multiplication Operator (*) or Asterisk

public static void main(String[] args) {

    System.out.println("Enter a  number of which you want to find factorial:");

    Scanner take = new Scanner(System.in);

              factorial = FindMultiplicationWOAsterisk(factorial,i);
    }
    System.out.println("Factorial of " + num + " is "+ factorial);
}
