Thread: Trouble Calling Method

Hey guys, thank you for the help with previous posts. Right now I am attempting to call a method getComm and getAnnComp but am slightly confused with the variable I should place before the method call. Here is the method, I highlighted my issue with all caps

 Scanner input=new Scanner(System.in);
        System.out.print("\nTotal Commission and Annual Sales Calculator\nThis "
                + "program will calculate Total Compensation based"
                + " upon\nthe percentage met of the $120,000 Annual Sales Target."
                + "\nThis program will also output a table of possible Total"
                + " Compensations\nin increments of $5,000 up to 1.5 times your inputted Annual Sales\n\n"
                + "Please enter your Total Annual Sales: ");
 
 
         //Check for Correct Entry Data
         try { 
            BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); 
            String line = in.readLine().trim(); 
 
            //Check for Null Entry
               if (line == null || line.length() == 0) { 
                  System.out.println("You did not enter a value"); 
                  return; 
            } 
 
               //Declare Annual Sales and Replace Commas/Dollar Signs
                annualSales = Double.parseDouble(line.replaceAll(",", "").replaceAll("\\$", ""));
 
            //Check for numerical value
        }   catch (NumberFormatException exception) { 
                 System.out.println("Error: Not a valid sales amount."); 
                 return; 
 
 
            //Check for IOException
        }   catch (IOException exception) { 
                 System.out.println("Error: " + exception.getLocalizedMessage()); 
                 return; 
        } 
 
         //Declare Sales
        spsales=new Salesperson(annualSales);
 
        //Output Total Commission
        System.out.println("\nYour Total Commission for the year is: $" +
                spsales.getComm()); //HERE IS MY PROBLEM
 
        //Output Total Compensation
        System.out.println("Your Total Compensation for the year is: $"+
                String.format("%.2f", spsales.getAnnComp())+ "+\n");  //HERE IS ALSO MY PROBLEM
 
...etc assume code closes correctly

the corresponding document is

   //Variable Definition

    double thresh = .80;
    String spName;    //holds the salesperson's name
    double annSales;   // Holds value for annual sales

    public double getComm()

    //Check if sale are greater than or equal to 80% of target. 
    if (annSales >= (target * thresh))
    {

            {   
            //Gets commission rate.
                commRate = (Comm * Accel_Factor)/100;
        commEarned = commRate * annSales;
            }
            else
            {
        commRate = Comm/100;
        commEarned = commRate * annSales;
            }
    }
    else
        {
        commRate = 0;
        commEarned = 0;
    }
    return commEarned;
    }
 
    /*
     * The getAnnComp method will calculate and return the total 
     * annual compensation.
     */ 
    public double getAnnComp ()
    {
    totalAnnComp = Fix_Sal + commEarned;
    return totalAnnComp;
    }
}

Do you get any runtime exception? If so, what is it?

I decided to use a different method figuratively and literally as I could not figure out why spsales could not be passed to GetComm(). With that being said I used

//Output Total Commission
        System.out.println("\nYour Total Commission for the year is: $" +
                Salesperson.CommEarned);

and was able to collect the variable efficiently

Thanks again!

I'm glad you've got it sorted out.

Going back to your original question (top of this thread) you had

spsales=new Salesperson(annualSales);
 
//Output Total Commission
System.out.println("\nYour Total Commission for the year is: $" +
    spsales.getComm()); //HERE IS MY PROBLEM
 
//Output Total Compensation
System.out.println("Your Total Compensation for the year is: $"+
    String.format("%.2f", spsales.getAnnComp())+ "+\n");  //HERE IS ALSO MY PROBLEM

Note the line "spsales=new Salesperson(annualSales);" because in the other class you define that as

Salesperson(double annualSales) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}

So I would have thought saying "new SalesPerson()" would throw an exception and give the error message. That's why I was asking about runtime exceptions.

Ah, I understand. I edited that out and corrected after posting. Thanks again for your help with everything.

As some background, Im in a 5 week course in which this program took an evolution of complexity each week. Some things are learned as we work, and it means a lot to have a source for help when needed. I look back at my questions and code from Week 2 and laugh at it's messy format. I'd love to share with you the final program and its evolution if you want to give it a look, I'm proud even though it may seem very basic to you haha! I won't post it here as someone may copy and paste it when Googling for help, but if you want to shoot me a PM, skype, or discord I'd be willing to send it!

Thanks again, and this concludes the programming for this class. Java is done for my major however I do plan on continuing to expand knowledge in the language
