    Default Double cannot be dereferenced

    Hey everyone,

    Im working on passing a double input to a method by the following code:

      //sales and sPerson Declaration
                 double sales;
                 sales = AnnualSales;
                 Salesperson sPerson = new Salesperson();
                 sPerson.setSales(sales);
     
            //Output Total Commission
            System.out.println("\nYour Total Commission for the year is: $" +
                    sPerson.getComm());
     
            //Output Total Compensation
            System.out.println("Your Total Compensation for the year is: $"+
                    String.format("%.2f", sPerson.getAnnComp())+ "+\n");
     
            //Output Table Headers
            System.out.println(" Total Sales           Total Compensation" + 
                               "\n ________________________________________");
     
            //UpperLimit Set: 150%
            int upperlimit = (int) ((AnnualSales/2)/5000);
     
            //Calculate Total Compensation in relevance with Total Sales
             for(int i=0;i<=upperlimit;i++){
              System.out.println(" $"+ sales+"       |         "
                      +"$"+String.format("%.2f", sales.getAnnComp()));   *****REFERENCE ERROR IS HERE*****
              sales+=5000;   
             }
       }

    The getAnnComp method code is here:

     public double getAnnComp ()
        {
        TotalAnnComp = Fix_Sal + CommEarned;
        return TotalAnnComp;
        }

    Any ideas? I'll continue working on a solution in the meantime. I can't just convert it to a string because the method used a double

    Thanks,

    //sales and sPerson Declaration
        double sales;
     
    // ... and later
     
    System.out.println(" $"+ sales+"       |         "
        +"$"+String.format("%.2f", sales.getAnnComp()));   *****REFERENCE ERROR IS HERE*****

    You have declared sales as a double and later you attempt to call a getAnnComp() method on it. The compiler message ("double cannot be dereferenced") is telling you that you can't do this because doubles don't have any methods.

    Why did you abandon the other thread which was about how to call the getAnnComp() method? Both Norm and I asked questions in that thread, but you seem to have walked away from it.

    I was at a standstill here because I could not convert the double to a string as the method required a double. Therefore I wrote a new method that allowed use of a tostring conversion and got this to work

    As for the my other thread, I could have swore I responded. I apologize and will go respond again now

    Thank you,

    No problem. I'll post a link to the other thread: trouble-calling-method. And close this one.
