Calculates factorials of n. Possibly wrong.

Factorial.java

import java.util.*;
 
public class Factorial {
    
	public static void main(String[] args)
	{
		
		// Declare variables
		Scanner sc = new Scanner(System.in);
		int n = 0, total = 1;
		
		// Get input for n
		n = sc.nextInt();
		
		for (int i = n; i >= 1; i--)
		{
        		total *= i;
		}
        
            System.out.println(n + "! = " + total);
	}
}

Okay cool, thanks for the tip!
