I really need help putting in another variable (Java) For handling the bottom 3 cases:

import javax.swing.JOptionPane;
import java.text.DecimalFormat;

public class CandleLine
{
 public static void main(String[] args)
 {
  double dollars, answer;
  int shipmentCode;

  dollars = getPrice();
  shipmentCode = getCode();
  answer = getTotalPrice(dollars,shipmentCode);
  output(answer,dollars);
  finish();
  }

 public static double getPrice()
 {
  double price = 0.0;
  boolean done = false;

  while (!done)
  {
   String answer = JOptionPane.showInputDia开发者_JAVA百科log(null,"Enter the original price\n(do not use commas or dollar signs)\n or click Cancel to exit:");

   if (answer == null) finish();

   try
   {
    price = Double.parseDouble(answer);
    if (price <= 0) throw new NumberFormatException();
    else done = true;
   }
   catch(NumberFormatException e)
   {
    JOptionPane.showMessageDialog(null,"Your entry was not in the proper format.","Error",JOptionPane.INFORMATION_MESSAGE);
   }
  }
  return price;
 }

 public static int getCode()
 {
  int code = 0;
  boolean done = false;

  while (!done)
  {
   try
   {
    String message = "Enter the shipment code:" + "\n\n1) Priority\n2) Express\n3) Standard\n\n";

    code = Integer.parseInt(JOptionPane.showInputDialog(null,message));

    if (code<1 || code>3) throw new NumberFormatException();
    else done = true;
   }
   catch(NumberFormatException e)
   {
    JOptionPane.showMessageDialog(null,"Please enter a 1, 2, or 3.","Error",JOptionPane.INFORMATION_MESSAGE);
   }
  }
  return code;
 }

 public static double getTotalPrice(double price, int shipmentcode)
 {
  double totalprice = 0.0;

  switch(shipmentcode)
  {
   case 1:
    totalprice = 14.95 + price;
    break;
   case 2:
    totalprice = 11.95 + price;
    break;
   case 3:
    totalprice = 5.95 + price;
    break;
  }
  return totalprice;
 }

 public static void output(double totalprice, double price)
 {
  DecimalFormat twoDigits = new DecimalFormat("$#.00");

  JOptionPane.showMessageDialog(null,"Your shipment fee is" + shipmentcode,"Shipment Fee",JOptionPane.INFORMATION_MESSAGE);
  JOptionPane.showMessageDialog(null,"Your total cost is" + twoDigits.format(totalprice),"Price Total",JOptionPane.INFORMATION_MESSAGE);
 }
 public static void finish()
 {
  System.exit(0);
 }
}

. . . . . . . . . The case 3 needs to be zero when it total price exceeds $75 (no shipping cost over that price). How do I implement this?

---

 case 3:
    if (price > 75 ) {
      totalPrice = price;
    } else {
      totalprice = 5.95 + price;
    }
    break;

---

So in total, how many possibilities are there for the shipping cost of an order?

---

final double [] shipmentprice = {14.95, 11.95, 5.95};
public static double getTotalPrice (final double price, final int shipmentcode)
{
    return price + shipmentprice[shipmentcode -1];
}

A shorter code, but not very object oriented. I'm not sure whether I see an Enum rising. :)
