Java中是否有指数运算符？

例如，如果提示用户输入两个数字，然后他们输入3和2，则正确答案为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);
    }
}

回答：

要通过用户输入执行此操作：

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
