the method in type not applicable for the arguments

Question

I am getting this error message:

2 errors found:

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

Answer 1

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.

Answer 2

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)

Answer 3

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

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

Answer 4

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())
