java - java.util.InputMismatchException 头疼

Question

import java.util.Scanner;
import java.io.*;
public class GardinierPayrollP2
{
  public static void main(String[] args) throws IOException
 {
  // int id;  //i.d. number
  // double hrsworkd; //hours worked
   double wkspay = 0.00;  //total amount before tax for an individual employee
   double netpay = 0.00; //net pay to an individual after tax
   double runningTotal = 0.00; //total amount of paid salaries
   double runningNetTotal = 0.00; //net total after tax 
   double runningTaxTotal = 0.00; //total taxes payed 
   double levelA = 12.00;
   double levelB = 14.50;
   double levelC = 16.00;
   double levelD = 20.00;
   //String name; //employees First Name
   //char level; //level of payment for employee
   final double taxRate = .08; //tax rate @ 8%
   double taxes = 0.00; //dollar amount of taxes payed
  
  
  File employees = new File("employees.txt");
  Scanner inputFile = new Scanner(employees);
  
  
  
  while (inputFile.hasNext())
  {
    
   String name = inputFile.nextLine();
   int id = inputFile.nextInt();
   char level = inputFile.next().charAt(0);
   double hrsworkd = inputFile.nextDouble();
   
   System.out.println(name + id + level + hrsworkd);
  }

 }
}

这就是我正在使用的。计算机科学第二年。还不是很精通解决错误。我知道有输入错误。我只是说不出为什么。DrJava 的输出是打印信息的前四行，然后抛出错误。这是输出
