Thread: Error of "cannot find symbol"

Hello big_c and welcome to the Java Programming Forums

You are getting the error because of this:

PayCheck aPayCheck = new PayCheck([B]hourlyWage[/B], hours);

hourlyWage is a double value and the PayCheck constructor is looking for an Integer value.

You could try type casting the hourlyWage variable to Integer:

import java.util.Scanner;
 
/**
   This program calculates the pay of an employee.
*/
public class PayCalculator
{
   public static void main(String[] args)
   {
 
      Scanner in = new Scanner(System.in);
 
      System.out.println("Hourly wage: ");
      double hourlyWage = in.nextDouble();
 
      [B]int hourlyWageInt = (int)hourlyWage;[/B]
 
      System.out.println("Hours worked: ");
      double hours = in.nextDouble();
 
      PayCheck aPayCheck = new PayCheck([B]hourlyWageInt[/B], hours);
 
      System.out.println("Pay: "+ aPayCheck.getPay());
   }
}

Even with my code you are still getting the same error?

That is strange because it is compiling fine for me...

Please make sure you change:

PayCheck aPayCheck = new PayCheck(hourlyWage, hours);

to

PayCheck aPayCheck = new PayCheck(hourlyWage[B]Int[/B], hours);

Yes you should check to make sure the PayCheck class is in the same directory as this could also be causing the problem.

Sorry EmeraldStones, I think you are wrong. If you look at the PayCalculator class, hourlyWage is infact set as double:

double hourlyWage = in.nextDouble();

And the PayCheck class constructor is looking for an Integer value and a double value in that order. The values passed to this constructor have to be Integer, Double.

public PayCheck(int PayCheck, double hours) {

You are trying to send:

PayCheck aPayCheck = new PayCheck(hourlyWage, hours);

And of course hourlyWage is a double value, not an Integer. You are sending double, double.

This is 100% what is causing this error as you can clearly see in Eclipse:

Are the PayCalculator & PayCheck classes both in your My Documents directory?

This error is generated because it looks like the PayCheck class cannot be located.

I can't see anything wrong with the code. In Eclipse it is all compiling fine.

Could you attach a screen shot of your IDE including the error? This might help me to see what is going on.

OK I can see your error!

In PayCalculator you call aPayCheck.getPay()

System.out.println("Pay: "+ aPayCheck.getPay());

But getPay() doesn't exist in the PayCheck class.

You have renamed getPay() to PayCheckgetPay()

To fix the error, update the PayCalculator class with:

System.out.println("Pay: "+ aPayCheck.[B]PayCheckgetPay()[/B]);

No problem

Glad I could help. Has this solved all your issues now?

I knew this question was coming

Can you please post the PayCalculator & PayCheck classes that you are now using and I will help you fix it.

okay heres the right ones now
class:

public class PayCheck
{
 
 
public PayCheck(double hourlyWage,double hours)
{
this.PayCheck=PayCheck;
this.hours = hours;
 
 
}
public int getPay()
 
{
if(hours>40*hourlyWage*150)
PayCheck=;
 
else if(hours<=40*hourlyWage)
PayCheck=PayCheck;
 
return PayCheck;
 
}
private double hourlyWage;
public int PayCheck;
private double hours;
}

Tester:

import java.util.Scanner;
 
/**
   This program calculates the pay of an employee.
*/
public class PayCalculator
{
   public static void main(String[] args)
   {
      Scanner in = new Scanner(System.in);
 
      System.out.println("Hourly wage: ");
      double hourlyWage = in.nextDouble();
 
      System.out.println("Hours worked: ");
      double hours = in.nextDouble();
 
      PayCheck aPayCheck = new PayCheck(hourlyWage, hours);
 
      System.out.println("Pay: "+ aPayCheck.getPay()) ;
   }
}

There are a few reasons why this code did not fuction properly.

The PayCheck value was always being passed as 0. Once that is corrected the variables need to be changed from int to double.

Can you please explain the calculations for me? Please give me an example input for hours & hourly wage and the desired output.

I'll post the updated code after..

Thanks

Thank you for the calculations EmeraldStones. They look correct to me.

big_c, here is the fixed code:

public class PayCheck {
 
    public PayCheck(double hourlyWage, double hours) {
        this.PayCheck = hourlyWage;
        this.hours = hours;
 
    }
 
    public double getPay()
 
    {
      [B]  if (hours <= 40) {[/B]
[B]
            PayCheck = (PayCheck * hours);
 
        } else if (hours > 40) {
 
            PayCheck = ((40 * PayCheck) + (hours - 40) * (PayCheck * 1.5));
 
        }[/B]
 
        return PayCheck;
    }
 
    private double hourlyWage;
    public double PayCheck;
    private double hours;
}
