Sales receipt, multiple choices (if/else), while loop, customer ability to change selections

None of the other posts seemed to fit accordingly.
I'm really struggling with producing this program without errors. I've come up with this below, however, if you run the program it is not adequately looping and if you choose the same candy twice the math isn't adding to the previous selection.
For the second part, I need to recode to adjust so that the customer may change the current selections if they'd like. So, I need the first part running perfectly.

* As long as the candy choice is in the proper range, prompt for the quantity,
* calculate the item total and subtotal; otherwise, print an error message. If it’s
* the first item in the purchase, ass it to the sales, a receipt with a $ sign for the
* item total. If not format the item without a $ sign for the item total
* and add it to the sales receipt. Start the process again when the customer wants
* to add another candy purchase. When the customer is done, the sales tax and the

Money format - how do I use it?

I'm a junior in high school. Having a tough time figuring out how to use money format. I'm doing an exercise in A Guide to Programming in Java (Second Edition) where I have to prompt the employees for the number of burgers, fries, and sodas.
Fries are $1.09, burgers are $1.69, and sodas are $0.99.
Here is my code:
import java.util.Scanner;
/**
* Order pg. 101
*
* Garret Mantz
* 2/10/2016
*/
public class Order {
public static void main(String[]args) {
final double pburgers=1.69;
final double pfries=1.09;
final double psodas=0.99;
final double ptax=0.065;
double burgers;
double fries;
double sodas;
double totaltax;
double total;
double tax;
double tendered;
double change;
Scanner input = new Scanner(System.in);
System.out.print("Enter the amount of burgers: ");
burgers = input.nextDouble();
System.out.print("Enter the amount of fries: ");
fries = input.nextDouble();
System.out.print("Enter the amount of sodas: ");
sodas = input.nextDouble();
System.out.print("Enter the amount tendered: ");
tendered = input.nextDouble();
totaltax = (burgers*pburgers)+(fries*pfries)+(sodas*psodas);
tax = totaltax*ptax;
total = totaltax + tax;
change = tendered - total;
System.out.println("Your total before tax is: \n" + totaltax);
System.out.println("Tax: \n" + tax);
System.out.println("Your final total is: \n" + total);
System.out.println("Your change is: \n" + change);
}
}
I just want to use the money format, but I'm not sure how. I'm sure it's a dumb question, but thank you for helping out!

Change your println to these, and see if that helps:
System.out.format("Your total before tax is: $%-5.2f\n", totaltax);
System.out.format("Tax: $%-5.2f\n", tax);
System.out.format("Your final total is: $%-5.2f\n", total);
System.out.format("Your change is: $%-5.2f\n", change);
There is also this:
NumberFormat formatter = NumberFormat.getCurrencyInstance();
String totalTaxString = formatter.format(totaltax);
String taxString = formatter.format(tax);
String totalString = formatter.format(total);
String changeString = formatter.format(change);
System.out.format("Your total before tax is: %s\n", totalTaxString);
System.out.format("Tax: %s\n", taxString);
System.out.format("Your final total is: %s\n", totalString);
System.out.format("Your change is: %s\n", changeString);
Output:
Your total before tax is: $8.53
Tax: $0.55
Your final total is: $9.08
Your change is: $10.92

You should not always try to format the output if it is not necessary.
Here's your problem :
System.out.printf("%nAS OF ");
System.out.printf("%1$TB %1$Td, %1$TY%n", dateTime);
System.out.printf("%nTotal Stock Cost: $" + totalStockCost);
System.out.printf("%nTotal Online Fees: $", totalOnlineFees);
System.out.printf("%nTotal Commissions: $", totalCommissions);
System.out.printf("%n%nTOTAL COST: $", totalCost);
You'll have to replace most of these with the following
System.out.printf("%nAS OF ");
System.out.printf("%1$TB %1$Td, %1$TY%n", dateTime);
System.out.println("Total Stock Cost: $" + totalStockCost);
System.out.println("Total Online Fees: $" + totalOnlineFees);
System.out.println("Total Commissions: $" + totalCommissions);
System.out.println("TOTAL COST: $" + totalCost);
Here is the output I get :

Java Lemonade Calculator

Assignment is to:
Display any welcome message at the top of the output screen
Create variables to hold the values for the price of a cup of lemonade.
Display the price per glass.
Ask the user for their name, and store it as a String object. Refer to the user by name, whenever you can.
Ask the user how many glasses of lemonade they would like to order. Save this as a variable with the appropriate data type.
Store the San Diego tax rate of 8% as a constant variable in your program.
Calculate the subtotal, total tax, and total price, and display it on the screen.
Ask the user how they would like to pay for the lemonade, and save the input as a char variable.
Ask the user to enter either 'm' for money, 'c' for credit card, or 'g' for gold
Using the DecimalFormat class, make all currency data printed to the screen display 2 decimal places, and also a '$" sign.
Need help figuring out how to get tax rate of 8% as a constant variable in my program
that way I can calculate the subtotal, total tax, and total price, and display it on the screen
So far this is what I have:
import java.util.Scanner;
import javax.swing.JOptionPane;
import java.text.DecimalFormat;
public class FirstProgram {
public static void main(String[] args) {
double cost = 7.55;
double amount = 7.55;
final double CA_SALES_TAX = 0.08;
int tax, subtotal, total;
subtotal = (int) (amount * cost);
tax = (int) (subtotal * CA_SALES_TAX);
total = tax + subtotal;
Scanner input = new Scanner(System.in);
double fnum = 7.55, tax1 = fnum * 0.08, answer = tax1 + fnum;
System.out.println("Welcome to the best Lemonade you'll ever taste! ");
System.out.println("My lemonade would only cost you a measly: $" + amount);
System.out.println("What is your name?");
String first_name;
first_name = input.nextLine();
System.out.println("Hi " +first_name+ ", how many glasses of lemonade would you like?");
fnum = input.nextDouble();
System.out.println("Subtotal: $" + (amount * fnum));
System.out.println("Tax: $" + (tax1 * CA_SALES_TAX));
tax1 = input.nextDouble();
Any help is appreciated

It looks like you already have the sales tax set as constant that is what the "final" keyword is being used for. As for your code i see some redundancies and am not sure as to why you are casting to integers. I made some mods for what I think you want it to do.
public static void main(String[] args) {
double cost = 7.55;
final double CA_SALES_TAX = 0.08;
double subtotal,tax,total;
Scanner input = new Scanner(System.in);
System.out.println("Welcome to the best Lemonade you'll ever taste! ");
System.out.println("My lemonade would only cost you a measly: $" + cost);
System.out.println("What is your name?");
String first_name = input.nextLine();
System.out.println("Hi " +first_name+ ", how many glasses of lemonade would you like?");
int fnum = input.nextInt();
//calc subtotal, tax, total
subtotal = fnum * cost;
tax = subtotal *CA_SALES_TAX;
total = tax + subtotal;
// print them all out
System.out.println("Subtotal: $" + (subtotal));
System.out.println("Tax: $" + (tax));
System.out.println("Total Price: $" + (total));
}

Why isn't my code calculating the correct total?

I'm having trouble trying to find out the running total. Each time I calculate the running total it miscalculates and gives me the incorrect answer. I'm not sure what it is. I cant tell if it has something to do with the method calling I did in main, the if statement in takeOrder or neither.
import java.text.DecimalFormat;
import javax.swing.JOptionPane;
public class MyCoffeeHouse {
public static void main(String[] args) {
String name = JOptionPane.showInputDialog(null, "What is your name?");
greetCustomer(name);
double totalPrice = takeOrder(name);
calculateFinalPrice(totalPrice);
}
public static void greetCustomer(String name) {
// greet customer
JOptionPane.showMessageDialog(null, "Hello " + name + ", Welcome to A Cup of Java!");
}
public static double takeOrder(String name) { // this method returns
String[] food = {"coffee", "bagel", "tea", "muffin"};
double[] price = {3.99, 1.99, 2.99, 4.99};
double totalprice = 0;
DecimalFormat dec = new DecimalFormat("#.00");
for (int index = 0; index < food.length; index++) {
JOptionPane.showMessageDialog(null, "Our menu offers: " + food[index] + "(s) which is " + "$"
+ price[index]);
}
int numItems =
Integer.parseInt(JOptionPane.showInputDialog(name + ", How many items are "
+ "you interested in purchasing?"));
// running total
for (int index = 0; index < numItems; index++) {
String input =
JOptionPane.showInputDialog(null, "Which items are you interested in purchasing from "
+ "our menu: coffee, bagel, tea, or muffin?");
if (input.equalsIgnoreCase(food[index])) {
totalprice += price[index];
}
}
return totalprice;
}
public static void calculateFinalPrice(double totalPrice) {
double salestax = (totalPrice * 0.07) + totalPrice; // 7% salestax
double finalprice;
DecimalFormat dec = new DecimalFormat("#.00");
int input =
JOptionPane.showConfirmDialog(null, "Would you like to dine in?", "Confirm",
JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE);
if (input == JOptionPane.YES_OPTION) {
finalprice = totalPrice + (salestax * 0.02);
JOptionPane.showMessageDialog(null, "The final price is $" + finalprice);
} else {
DecimalFormat dec = new DecimalFormat("#.00");
JOptionPane.showMessageDialog(null, "The final price is $" + dec.format(salestax));
}
}
}

When you do
double salestax= totalPrice + 0.07; //7% salestax
This means you are adding 7 cents in tax, not 7 percent. To add 7 % you need to multiply the original price by 1.07 or 100% + 7% = 107%
double salestax= totalPrice * 1.07; // add 7% salestax
When you do
finalprice=salestax + 0.02;
You are adding 2 cents. Note: at this point you can add another 2% however adding 7% and another 2% is not the same at adding 9% as 1.07 * 1.02 > 1.09.

Get the chosen food item before you loop to test for the price.
// First get the input
String input=JOptionPane.showInputDialog(null,//
"Which items are you interested in purchasing from "
+ "our menu: coffee, bagel, tea, or muffin?");
for(int index=0;index<numItems;index++) {
// now loop all of the items, and check what was picked.
if(input.equalsIgnoreCase(food[index])) {
totalprice+=price[index];
}
}
