Answer 1

import java.util.Scanner;

class FactorialDemo{

public static void main(String args[]){

//Scanner object for capturing the user input

Scanner scanner = new Scanner(System.in);

System.out.println("Enter the number:");

//Stored the entered value in variable

int num = scanner.nextInt();

//Called the user defined function fact

int factorial = fact(num);

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

}

static int fact(int n)

{

int output;

if(n==1){

return 1;

}

output = fact(n-1)* n;

return output;

}
