the method in type not applicable for the arguments

I am getting this error message:

2 errors found:

Error: The method determineTaxRate(double) in the type PayCalculator is not applicable for the arguments ()

Error: The method calculateNetPay(double, double) in the type PayCalculator is not applicable for the arguments ()

Can you tell me what to do to fix this?

public class PayCalculator

    private double hourlyRate;
    private double hoursWorked;

     /**
     * Two parameter constructor
     * Add hourlyRate and hoursWorked
     * @param the hourly rate

     */
    public PayCalculator(double aHourlyRate, double aHoursWorked)
    {
        hourlyRate = aHourlyRate;
        hoursWorked = aHoursWorked;
    }

    /**
    * sets the hourly rate
    * @return hourlyRate
    */ 
    public void setHourlyRate(double aHourlyRate)
    {
        hourlyRate = aHourlyRate;
    }

    /**

    public double getHourlyRate()
    {
        return hourlyRate;
    }

    /**

    public void setHoursWorked(double aHoursWorked)
    {
        hoursWorked = aHoursWorked;
    }

you have declared your method like this :

public double determineTaxRate(double grossPay)

and later invoke it like this :

determineTaxRate()

obviously,you have missed a parameter when invoking the method

fix this by determineTaxRate(someDoubleVar)

your method defined with one argument.But you are not passing any parameters.

For calculateNetPay() also you are doing the same thing.

You haven't specified arguments for the methods which you are calling from printData() method, for example:

System.out.println("Net Pay: " + calculateNetPay());

You are calling calculateNetPay() with 0 arguments, where as in your method defnition you have specified, it needs 2 double arguments.

public double calculateNetPay(double grossPay, double tax) { ... }

Same applies for other errors you are getting.

You are calling

determineTaxRate()

But your method is defined as this:

public double determineTaxRate(double grossPay)
{

Same with your other error. You need to pass a double to the method. Such as this:

determineTaxRate(calculateGrossPay())
