Java Factorial Example

This Java Factorial Example shows how to calculate factorial of

a given number using Java.

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
