java幂的类封装怎么补充代码

Question

class Mi {
/*类Mi
  成员变量 double型diShu,zhiShu
  含参构造方法Mi(double a,double b)
  输出方法shuChu(),按幂的形式输出结果，如 2^4
  获取底数方法getDiShu(),返回幂的底数
  获取指数方法getZhiShu(),返回幂的指数
  muti(Mi r) 计算同底数幂的乘法，指数相加；底数不同，报错
  div(Mi r) 计算同底数幂的除法，指数相减；底数不同，报错
  power(Mi r) 计算同底数幂的乘方
*/
double diShu,zhiShu;
//---begin---

//【代码】声明double型变量diShu,zhiShu

 
//【代码】含参构造方法，将参数赋值给变量diShu,zhiShu
 
double getDiShu() {
    return diShu;

double getZhiShu() {
    return zhiShu;
