数组/方法中未存储任何功能不正常的内容

Question

目的：“使用以下数组作为字段编写工资单类：雇员ID：一个由七个整数组成的数组来保存雇员标识号。该数组应使用以下数字初始化：568845, 4520125, 7895122, 8777541, 8451277, 1302850, 7580489小时：一个由七个整数组成的数组来保存每个雇员的工作小时数。pay费率：一个由七个双精度组成的数组来保存每个雇员的小时工资率工资：一个由七个双精度组成的数组来保存每个雇员的总工资。该类应该通过他的子对象来关联每个数组中的数据。该类应该有一个方法来接受雇员的标识号作为参数并返回该雇员的总工资。”

使用Grosspay方法设置/获取方法：

public class Payroll{
   private int [] employeeID ={5658845, 4520125, 7895122, 8777541, 8451277, 1302850, 7580489};
   private int [] hours = new int [7];
   private double [] wages = new double [7];
   private double [] payRate = new double [7];


   public void setEmployeeID(int a, int emp){
      employeeID[a] = emp;
   }
   public void setHours(int a, int hr){
      hours[a] = hr;
   }
   public void setWages(int a, int wgs){
      wages[a] = wgs;
   }
   public void setPayrate(int a, int prt){
      payRate[a] = prt;
   }
   public int getEmployeeID(int a){
      return employeeID[a];
   } 
   public int getHours(int a){
      return hours[a];
   }
   public double getWages(int a){
      return wages[a];
   }
   public double getPayrate(int a){
      return payRate[a];
   }
   public void Grosspay(){
      for(int a = 0; a < 7; a++){
         wages[a] = hours[a] * payRate[a];

      }

   } 
}

执行所有操作的地方：

import java.util.Scanner;
public class TestPayroll{
   public static void main(String [] args){
      Scanner in = new Scanner(System.in);
      Payroll pr = new Payroll();
      int hr;
      double prt;

      for (int a = 0; a < 7; a++){
         System.out.println("Enter in the hours worked by employee " + pr.getEmployeeID(a));
         hr = in.nextInt();
         pr.setHours(a,hr);
         while(hr < 0){
            System.out.println("Enter in a number greater than 0");
            hr = in.nextInt();
            pr.setHours(a,hr);
         }
         System.out.println("Enter in the pay rate for employee " + pr.getEmployeeID(a));
         prt = in.nextDouble();
         while(prt < 6.00){
            System.out.println("Enter in a payrate greater than 6.00");
            prt = in.nextDouble();
         }

      }
      pr.Grosspay();
      for(int a = 0; a < 7; a++){
         System.out.println("Employee " + pr.getEmployeeID(a) + " has a gross pay of " + pr.getWages(a));
      }


   }

我运行这个程序，除了打印工资之外，一切都很好。工资不是小时[a]*pay费率[a]的结果，而是打印0.0。我在想Grosspay方法可能没有按照我认为的方式运行。或者可能是我设置了工资[a]=wgs，但代码中没有使用wgs，因此工资数组中没有存储任何内容。那么我的代码有什么问题，0.0正在打印出来？感谢任何帮助。
