Find Power of a number in Java?

There are two ways to find power of a number. One is iterative which is very simple(Just multiply the number power number of times) and other is recursive. Following is the code to get power of a number in recursive way.

Code : 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

<b>/**  * Created with IntelliJ IDEA.  * User: aniket  * Date: 6/12/13  * Time: 3:08 PM  * To change this template use File | Settings | File Templates.  */ public class PowerCalculator {       public static int pow(int base, int power){           if(power == 1){             return base;         }         if(power % 2 == 0){             return pow(base, power/2) * pow(base, power/2);         }         else {             return pow(base, power/2) * pow(base, power/2) + base;         }     }       public static void main(String args []){           System.out.println("4 raise to 2 : " + PowerCalculator.pow(4,2));       }   } </b>

Output :

4 raise to 2 : 16
