Factorial Program in Java - Java Program for Factorial of a Number
Factorial Program in Java :
- Factorial of n is the product of all positive descending integers. Factorial of n is denoted by n!. For example: 3! = 3*2*1 = 6
Sample Code
import java.util.Scanner;
public class factorial
{
public static void main(String[] args)
{
int fact = 1;
Scanner sc = new Scanner(System.in);
System.out.println("Enter the factorial of ___ ?");
int number = sc.nextInt();
for (int i = 1; i <= number; i++)
{
fact = fact * i;
}
System.out.println("Factorial of " + number + " is: " + fact);
}
}
Output
Enter the factorial of ___ ? 5
Factorial of 5 is: 120
Enter the factorial of ___ ? 10
Factorial of 10 is: 3628800
