Writing methods We want to write a method that will enable u

Writing methods We want to write a method that will enable us to calculate a number to a given power. In other words, we are writing a method to mimic what the Math.pow() method we have seen before does. To write this method use the following requirements: The method should return an integer. It should have two parameters x and y both integers. The name of this method will be power(). For the sake of being able to use the method without creating an object, the method must be a static method.

Solution

Hi, Please find my implementation.

public class Power {

   public static int power(int x, int y)

   {

       if( y == 0)

           return 1;

       else if (y%2 == 0)

           return power(x, y/2)*power(x, y/2);

       else

           return x*power(x, y/2)*power(x, y/2);

   }

  

   public static void main(String[] args) {

       System.out.println(\"Power(3,4): \"+power(3, 4));

   }

}

/*

Sample Run:

Power(3,4): 81

*/
