读取包含与特定子类相关的不同信息的多行文件？

Question

所以我开发了一种迭代文件的方法，该文件可能在每行中包含不同的信息，然后将它们添加到通用的ArrayList中。正如您在代码中看到的，我有三个源自超类Employee的子类;每小时，薪水和佣金。我只是想知道是否有更好的方法对此进行编码？

这是我的代码：

public void loadData(File inFile) throws IOException
{
    Scanner in = new Scanner (inFile);
    String employeeName;
    String employeeNum;
    String empDepartment;
    char type;
    while(in.hasNext())
    {
        String employee = in.nextLine();
        String [] employeeList = employee.split(" ");
        //This if reads in an hourly employee
        if(employeeList.length == 6)
        {
            employeeName = employeeList[0];
            employeeNum = employeeList[1];
            empDepartment = employeeList[2];
            type = employeeList[3].charAt(0);
            double hourlyPay = Double.parseDouble(employeeList[4]);
            int hoursWorked = Integer.parseInt(employeeList[5]);
            employees.add(new Hourly(employeeName, employeeNum, empDepartment, type, hourlyPay, hoursWorked));
        }
        //This if reads in a Salary employee
        else if(employeeList.length == 5)
        {
            employeeName = employeeList[0];
            employeeNum = employeeList[1];
            empDepartment = employeeList[2];
            type = employeeList[3].charAt(0);
            double yearlySalary = Double.parseDouble(employeeList[4]);
            employees.add(new Salary(employeeName, employeeNum, empDepartment, type, yearlySalary));
        }
        else if(employeeList.length == 9)
        {
            employeeName = employeeList[0];
            employeeNum = employeeList[1];
            empDepartment = employeeList[2];
            type = employeeList[3].charAt(0);
            int weeksSinceStart = Integer.parseInt(employeeList[4]);
            double baseWklySalary = Double.parseDouble(employeeList[5]);
            double weeklySales = Double.parseDouble(employeeList[6]);
            double totalSales = Double.parseDouble(employeeList[7]);
            double commissionRate = Double.parseDouble(employeeList[8]);
            employees.add(new Commission(employeeName, employeeNum, empDepartment, type, weeksSinceStart, baseWklySalary, weeklySales, totalSales, commissionRate));
        }
    }
    in.close();
}
