Write a Java Program to find Factorial using While loop


Factorial of any number is the product of an integer and all the integers below it

For example ::  factorial of 5 is 5! =5* 4 * 3 * 2 * 1 = 120.

In below source code i will show you how to Write a  Java program to find factorial using while loop.

 

SOURCE CODE ::

 

import java.util.Scanner;

public class Factorial{

    public static void main(String[] args) 
    {
        
        int n, fact=1;
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter any number :");
        n=sc.nextInt();
        
        int i=1;
        while(n>=i)
        {
            fact=fact*i;
            i++;
        }
        System.out.println("Factorial is :" +fact);
    }
        
    }

 

OUTPUT ::

 

Enter any number :
9
Factorial is :362880
