public class Calculator

{

public static double getProd(double num, int times)

{//計算次方

double sum = 1;

for (int i = 0 ; i < times ; i ++)

{

sum = sum * num;

}

return sum;

}

public static double getStepProd(double num)

{//階乘

double sum = 1;

for (int i = 1 ; i <= num ; i ++)

{

sum = sum * i;

}

return sum;

}

public static void main(String[] args)

{

System.out.println(Calculator.getProd(4, 4));

System.out.println(Calculator.getStepProd(3));

}

}

執行結果:
