Java中是否有指数运算符？

例如,如果用户被提示输入两个数字,他们进入3和2,正确的答案应该是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);
    }
}
