Does Java have an exponential operator

Question

Is there an exponential operator in Java   For example  if a user is prompted to enter two numbers and they enter 3 and 2  the correct answer would be 9   import java util Scanner  public class Exponentiation        public static double powerOf  double p            double pCubed           pCubed   p p          return  pCubed              public static void main  String    args            Scanner in   new Scanner  System in            double num   2 0          double cube               System out print   Please put two numbers              num   in nextInt             cube   powerOf num            System out println  cube

There is no operator  but there is a method   Math pow 2  3     8 0  Math pow 3  2     9 0     FYI  a common mistake is to assume 2   3 is 2 to the 3rd power  It is not  The caret is a valid operator in Java  and similar languages   but it is binary xor

The easiest way is to use Math library   Use Math pow a  b  and the result will be a b  If you want to do it yourself  you have to use for-loop     Works only for b  gt   1 public static double myPow double a  int b       double res  1      for  int i   0  i  lt  b  i              res    a            return res      Using   double base   2  int exp   3  double whatIWantToKnow   myPow 2  3

To do this with user input       public static void getPow        Scanner sc   new Scanner System in       System out println  Enter first integer            3     int first   sc nextInt        System out println  Enter second integer            2     int second   sc nextInt        System out println first     to the power of     second     is               int  Math pow first  second          outputs 9

In case if anyone wants to create there own exponential function using recursion  below is for your reference   public static double power double value  double p            if  p  lt   0              return 1           return value   power value  p - 1

you can use the pow method from the Math class  The following code will output 2 raised to 3  8   System out println Math pow 2  3

There is the Math pow double a  double b  method  Note that it returns a double  you will have to cast it to an int like  int Math pow double a  double b
