Question

Replace <missing value> and <missing code> with your answers. Your code should compute the factorial of n. For example, if n = 5, your code should compute the following 5 * 4 * 3 * 2 * 1 (which is 120).

public static void main(String[] args)
{

Scanner scanner = new Scanner(System.in);
int n = scanner.nextInt();

int factorial = <missing value>;

<missing code>

System.out.println("factorial = " + factorial);

Answer 1

If you have any doubts, please give me comment...

import java.util.Scanner;

public class Factorial {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        int n = scanner.nextInt();

        int factorial = 1;

        for (int i = n; i > 0; i--) {

            factorial *= i;

        }

        System.out.println("factorial = " + factorial);

    }

}
