Write a Java Program that find the factorial of a number

                                                        Week – 1

 

 c)Aim: To Write a Java Program that find the factorial of a number

Source code:
import java.io.*;
import java.util.Scanner;
 
class Factorial
{
public static void main(String args[])
{
int n, c, fact = 1;
 
System.out.println(“Enter an integer to calculate it’s factorial:”);
Scanner in = newScanner(System.in);
 
n = in.nextInt();
 
if ( n < 0 )
System.out.println(“Number should be non-negative.”);
else
{
for ( c = 1 ; c <= n ; c++ )
fact = fact*c;
 
System.out.println(“Factorial of “+n+” is = “+fact);
}
}
}
Expected Output:
 
Enter an integer to calculate it’s factorial : 6
Factorial of 6 is = 720
