public class NumberFactorial {
public static void main(String[] args) {
int number = 5;
/*
* Factorial of any number is! n.
* For example, factorial of 4 is 4*3*2*1.
*/
int factorial = number;
for(int i =(number – 1); i > 1; i–)
{
factorial = factorial * i;
}
System.out.println(“Factorial of a number is ” + factorial);
}
}
/*
Output of the Factorial program would be
Factorial of a number is 120
