    Default Simple Commission Calculator

    I'm struggling to get the incentive part correct. And I have no idea where to start to display the table. Here are the instructions and the code below.

    ∑ A salesperson will continue to earn a fixed salary of $50,000.00 per year. The current sales target for every salesperson is $120,000.00 per year.
    ∑ The sales incentive will only start when 80% of the sales target is met. The current commission is 7.5% of total sales.
    ∑ If a salesperson exceeds the sales target, the commission will increase based on an acceleration factor. The acceleration factor is 1.25.
    ∑ The application should ask the user to enter annual sales, and it should display the total annual compensation.
    ∑ The application should also display a table of potential total annual compensation that the salesperson could have earned, in $5000 increments above the salespersonís annual sales, until it reaches 50% above the salespersonís annual sales.

    Sample Table: Assuming a total annual sales of $100,000, the table would look like this:

    Total Sales Total Compensation
    100,000 <Program Calculated Value>
    105,000 <Program Calculated Value>
    <etc>

    Here's what I have so far.

    package commissioncalculator;
     
    import java.text.DecimalFormat;
    import javax.swing.JOptionPane;
     
     
    /**

    public class CommissionCalculator {

           double pay; //Salesperson's pay

           double incentive; //sales incentive
     
           DecimalFormat dollar = new DecimalFormat("#,##0.00");
           DecimalFormat percent = new DecimalFormat("##0.0%");
           input = JOptionPane.showInputDialog("Enter the annual salary.");
           salary = Double.parseDouble(input);
           input = JOptionPane.showInputDialog("Enter current commission rate.");
           rate = Double.parseDouble (input);
           input = JOptionPane.showInputDialog("Enter the current sales target.");
           sales = Double.parseDouble (input);
     
           commission = rate * salary;
           pay = commission + salary;
           JOptionPane.showMessageDialog(null, "Commission rate is " +
            percent.format(rate) + ". The amount of pay is $" + dollar.format(pay));
     
            public incentive() {
              if (sales>=(.80 * sales) && sales<=120,000)
                incentive = (.75 * sales);
              else if (sales>120,000)
                incentive = (1.25 * .75 * sales);
        }
        }

    Can you show what the code does now, explain what is wrong and show what the output should be?

    For a first attempt at displaying the table, just use the println() method. Later you can look into using printf() which will give you some formatting.

    The first message comes through, but the second is "Total SalesTotal Compensation 100,000.00100,000.0075,000.00"

    I want it to look like this:

    Total Sales Total Compensation
    100,000 75,000
    105,000 78,750

    The table needs to increase by 5,000 until it reaches 50% above the salary. And the compensation takes into consideration the incentive.

    Add a newline character: ("\n") where you want a line to end and the following part of the String to be on the next line.
    Add some spaces between the numbers: num1 + " " + num2
    so you can see where one ends and the next starts.

    Something like this:

              JOptionPane.showMessageDialog (null,
              ("n")  "Total Sales"    +    "Total Compensation" + ("/n")
              ("n") ( dollar.format(sales)  + (dollar.format(sales) + dollar.format(incentive) )  ) + ("/n")
              ("n") ( (dollar.format(sales) + 5000) + (dollar.format(sales) + dollar.format(incentive) )))("/n");

    It still says ")" expected.

    Make sure all the ( have a matching ).

    It looks like you might need some + operators to connect all the parts of the String into one String.

    You don't need the ()s around the "\n"

    Ok, I think I got that solved, but now it doesn't like the "null"

      JOptionPane.showMessageDialog (null,
              "n" + "Total Sales"    +    "Total Compensation" + "/n" +
              "n" + ( dollar.format(sales)  + (dollar.format(sales) + dollar.format(incentive) )  ) + "/n" +
              "n" + ( (dollar.format(sales) + 5000) + (dollar.format(sales) + dollar.format(incentive) ))) + "/n";

    What other choices do I have?

    Where is the "void"? The error message did not give a line number.

    What error messages does the compiler give? Can you compile the code without trying to execute it? You won't be able to execute the code with compiler errors.

    Compile the code and copy the compiler's error messages here.

    If you use the compiler, it will generate error messages that can be copied and pasted.
    Here is a sample:
    TestSorts.java:138: cannot find symbol
    symbol  : variable var
    location: class TestSorts
             var = 2;
             ^

    If you can't post the text of the error messages attach images, not a pdf.

    Default Re: Simple Commission Calculator

    I don't recognize that message. Is it from the IDE, not from the javac compiler program?

    I don't know why beginners are encouraged to use an IDE before they understand how to write simple programs and how to understand the compiler's error messages.

    If you want help, Copy the source file to another folder and use the javac command to compile the program. It will produce error messages that can be copied to the forum.

    I'm not sure.
    Unfortunately, it's a self paced class, so they make us jump right into the IDE.

    CommissionCalculator.java:46: not a statement
    This part of the message says that there is something on line 46 that is not part of a statement.
    Is that where there was a missing + in the middle of a String?

    There was a long complicated String built there. Start over writing the code to build the String.
    Start with a short String that fits on one line. Compile it and correct any errors.
    Then add a little more to it, compile it and correct errors.
    Then add a little more, compile it and correct errors.

    Continue until you have the full String that you want.
