java需要帮助在这个程序中查找错误，编译但不是计算机所必需的数字

Question

该程序编译并运行，但不计算保险费。我已经做了好几天了，还没弄明白。它以前在另一个版本中运行，但我们现在需要有两个类，现在它不计算保险，或者在每个答案中显示为零。我们还需要使用窗格进行输入

// The Premium class represents an insurance premium cost for an individual policy.

  This program will demonstrate the Premium and BMI classes. This program will prompt users for input, 
  use that input to calculate BMI and their insurance rate.
  Output will be the customer profile: name, age, smoker status, height, weight and insurance premium cost. 
  Program will then ask user if they want to create another profile.

如果没有得到任何编译器错误，那么这是代码中的逻辑错误

在我看来calculateInsurance方法从未被调用过
