title: Adding a final double to my program
body: <p>I'm attempting to make a few doubles in my code final.  I've tried a few methods such as "public static final," just "final," etc.</p>
  
  <pre><code>import java.util.Scanner;
  import java.text.DecimalFormat;
  
  public class Pay_stub {
      public static void main(String[] args) {
          Scanner input = new Scanner(System.in);
          DecimalFormat df = new DecimalFormat("#.00");
  
          double fedinctax = .15;
          double statetax = .035;
          double socsectax = .0575;
          double meditax = .0275;
          double penplan = .05;
          double healthins = 75;
  
          double hoursworked;
          double hourlyrate;
  
          double netpay;
          double grosspay;
  
          String firstname, lastname;
  
          System.out.println("Enter employee first name: ");
          firstname = input.next();
  
          System.out.println("Enter employee last name: ");
          lastname = input.next();
  
          System.out.println("Enter hours worked: ");
          hoursworked = input.nextDouble();
  
          System.out.println("Enter hourly rate: ");
          hourlyrate = input.nextDouble();
  
          grosspay = hoursworked * hourlyrate;
  
          double fit = grosspay * fedinctax;
          double st = grosspay * statetax;
          double sst = grosspay * socsectax;
          double mmt = grosspay * meditax;
          double pp = grosspay * penplan;
          double total = fit + st + sst + mmt + pp + healthins;
          double net = grosspay - total;
  
          System.out.println(firstname + lastname + "'s monthly paycheck is: ");
          System.out.println("Gross Pay: " + (df.format(grosspay)));
          System.out.println("Federal Income Tax: " + fit);
          System.out.println("State Tax: " + st);
          System.out.println("Social Security Tax: " + sst);
          System.out.println("Medicare/Medicaid Tax: " + mmt);
          System.out.println("Pension Plan: " + pp);
          System.out.println("Health Insurance: " + healthins);
          System.out.println("Net Pay: " + (df.format(net)));
      }
  }
  </code></pre>
  
  <p>These are what I would like to make final:</p>
  
  <pre><code>    double fedinctax = .15;
      double statetax = .035;
      double socsectax = .0575;
      double meditax = .0275;
      double penplan = .05;
      double healthins = 75;
  </code></pre>
  
  <p>I just am not sure where I'm supposed to put the final lines in the code, or how they are supposed to be written</p>
