Java Program Example on Factorial

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
