Program to find Factorial using loop

Factorial of n is the product of all positive descending integers. Factorial of n is denoted by n!. For example: 4! = 4*3*2*1 = 24  

package javabox;

class FactorialExample{  

 public static void main(String args[]){  

  int i,fact=1;  

  int number=5;//It is the number to calculate factorial    

  for(i=1;i<=number;i++){    

      fact=fact*i;    

  }    

  System.out.println("Factorial of "+number+" is: "+fact);    

 }  

}  

Output - 

Factorial of 4 is: 24
