java实现给定一个double类型的浮点数base和int类型的整数exponent。求base的exponent次方。

public class Solution {    public double Power(double base, int exponent) {        double result = 1.0;if (exponent == 0)return 1;else if (exponent > 0){for (int i = 1; i <= exponent; i++){result *= base;}} else if (base == 0)throw new RuntimeException("分母不能为零");for (int i = 1; i <= -exponent; i++){result *= base;}return exponent > 0 ? result : (1 / result);  }    public static void main(String[] args){double base = 0;int exponent = 2;Solution s = new Solution();System.out.println(s.Power(base, exponent));}}
