A basic GUI commission calculator

[M Gerber]

So, I am supposed to write a program that calculates the total annual compensation for a salesman using user input for the salary, sales, and commission rate (list of 3 predefined commission rates. have to display in dollar format the amount of commission and total annual salary.

    //attributes of class, stored data
   private double sales;
   private double salary;
   private double rate;
   //and a total field? beware stale data.
   
   //store sales argument from sales field
   public void setSales(double sal)
   {
       sales = sal;
   }
   
   //store salary
   public void setSalary(double pay)
   {
       salary = pay;
   }

   public void setRate(double rat)
   {
       rate = rat;
   }
   
   //the get commands
   public double getSales()
   {
       return sales;
   }
   
   public double getSalary()
   {
       return salary;
   }
   
   public double getRate()
   {
       return rate;
   }
   //calcualate total
   public double getTotal()
   {
       //reading page 16 week 2 
       return sales * rate;
   }
}

CalcTest method

import java.text.DecimalFormat;
import java.util.Scanner;


public class CalcTest
{
    public static void main(String[] args)
    {
        CommCalc calc; //references the class CommCalc
        double salary, //starting salary
                rate,// starting rate
                sales,//starting sales

         CommCalc test;
        test = new CommCalc();
        
       DecimalFormat dollar = new DecimalFormat("#,##0.00"); //Initializes decimal format
       DecimalFormat percent = new DecimalFormat("##0.0%"); //Initializes decimal format
       
       Scanner keyboard = new Scanner(System.in);
       
       System.out.println("What is the amount of sales?");
       sales = keyboard.nextDouble();
       
       System.out.println("What is your annual salary?");
       salary = keyboard.nextDouble();
       
       
        System.out.println("Which rate do you want to use? .05" + 
                                                           " .10" +
                                                         " or .15?");
        rate = keyboard.nextDouble();
        
       Total = rate * sales + salary;
        
        System.out.println("This is your total salary from " +
                                         "your sales. $" + Total);
        
    }
}

I know that i have to fix some of the semantics .
I have this code that I made earlier, is there an easy way to make it into a GUI interface? Or will I have to go throughthe code lines to add the JOptionPane?
And I am a little confused on how to make a list (array) for the commission rate.

[fred rosenberger]

shouldn't the package declaration come before the imports?

[M Gerber]

Sorry I should have said that I am using NetBeans 8, that is where it put them.

[M Gerber]

The code will compile and run, I am just stuck on incorporating it into a JOptionPane or another GUI interface, could I just add code to the original?
Also the commission rate should be in a list (of 3 choices) and I am a little green(horn) in making arrays.

You should create a separate class to represent the view which will be the front-end of the application containing the labels, text fields and buttons for user interaction... Create another class to control the interaction between the user events in the view class components and how these events will interact with the interface of the CommCalc class to get the desired functionality...
