Cant get this to run PAYROLL PROJECT java

package EmployeePayAppMRM;
import javax.swing.JOptionPane;
public class java
{
public static void main(String[] args)
{
String firstName;
String lastName;
String fullName;
String itemsSold;
String valueItems;
double basePay;
double totalPay;
double valueSold;
int numberSold;
final double ITEM_MIN = 10;
final int VALUE_MIN = 2500;
final int BONUS = 500;
firstName = JOptionPane.showInputDialog(" Enter employee's first name:");
lastName = JOptionPane.showInputDialog(" Enter employee's last name:");
fullName = JOptionPane.showInputDialog(" Enter base pay for " + firstName + " " + lastName + ":");
basePay = Double.parseDouble(fullName);
itemsSold = JOptionPane.showInputDialog(" Enter number of items sold for " + firstName + " " + lastName + ":");
totalPay = Double.parseDouble(fullName);
fullName = JOptionPane.showInputDialog(" Enter value of items sold for " + firstName + " " + lastName + ":");
valueSold = Double.parseDouble(fullName);
basePay = 1000;
if ( itemsSold > ITEM_MIN) //ERROR HERE (bad operand)
totalPay = (basePay + BONUS);
else if (valueSold >= VALUE_MIN)
totalPay = (basePay + BONUS);
else
totalPay = basePay;
System.out.println("this" + firstName + " " + lastName + " " + "will be paid" + totalPay "for selling" + itemsSold "items valued at $" + valueSold); //ERROR HERE
System.exit(0);
}
}

The first problem is about types, for the second you just miss some +
itemsSold is a String
ITEM_MIN is a double
Do like this, of parse it before
if(Double.parseDouble(itemsSold) > ITEM_MIN)
totalPay = (basePay + BONUS);
Finally, you don't need to define the variable and do the assignement later, just do it at the same time, once reoganisating all :
final double ITEM_MIN = 10;
final int VALUE_MIN = 2500;
final int BONUS = 500;
String firstName = JOptionPane.showInputDialog(" Enter employee's first name:");
String lastName = JOptionPane.showInputDialog(" Enter employee's last name:");
String fullName = JOptionPane.showInputDialog(" Enter base pay for " + firstName + " " + lastName + ":");
double itemsSold = Double.parseDouble(JOptionPane.showInputDialog(" Enter number of items sold for " + firstName + " " + lastName + ":"));
double valueSold = Double.parseDouble(JOptionPane.showInputDialog(" Enter value of items sold for " + firstName + " " + lastName + ":"));
double totalPay = 0;
double basePay = 1000;
if (itemsSold > ITEM_MIN) {
totalPay = (basePay + BONUS);
} else if (valueSold >= VALUE_MIN) {
totalPay = (basePay + BONUS);
} else {
totalPay = basePay;
}
System.out.println("this" + firstName + " " + lastName + " " + "will be paid" + totalPay + "for selling" + itemsSold + "items valued at $" + valueSold);

code works but it keeps giving me the error: InputMismatchException and

what am I doing wrong?
Thanks, HG

Take input food_one to price three like this:
food_one = fileIn.nextLine();
price_one = fileIn.nextDouble();
fileIn.nextLine();
food_two = fileIn.nextLine();
price_two = fileIn.nextDouble();
fileIn.nextLine();
food_three = fileIn.nextLine();
price_three = fileIn.nextDouble();
It should work.

I changed the format in which you are storing the food and price (in prices.txt) to the following (with food and price separated by a delimiter, in this case a colon)
Pizz:20.10
Burger:10.30
Coffee:5.99
I changed the code to the following and now it is working. Hope this helps
// give strings and numbers varibles
String[] foodPrice = fileIn.nextLine().split(":");
food_one = foodPrice[0];
price_one = Double.parseDouble(foodPrice[1]);
foodPrice = fileIn.nextLine().split(":");
food_two = foodPrice[0];
price_two = Double.parseDouble(foodPrice[1]);
foodPrice = fileIn.nextLine().split(":");
food_three = foodPrice[0];
// fileIn.nextLine();
price_three = Double.parseDouble(foodPrice[1]);

Forgot to comment out fileIn.nextLine(); around like 46
your trying to put the name of a food into a nextDouble()
//give strings and numbers varibles
food_one = fileIn.nextLine();
//fileIn.nextLine();
price_one = fileIn.nextDouble();
fileIn.nextLine();
food_two = fileIn.nextLine();
//fileIn.nextLine();
price_two = fileIn.nextDouble();
//fileIn.nextLine();
food_three = fileIn.nextLine();
//fileIn.nextLine();
price_three = fileIn.nextDouble();
Should be:
//give strings and numbers varibles
food_one = fileIn.nextLine();
//fileIn.nextLine();
price_one = fileIn.nextDouble();
//fileIn.nextLine();
food_two = fileIn.nextLine();
//fileIn.nextLine();
price_two = fileIn.nextDouble();
//fileIn.nextLine();
food_three = fileIn.nextLine();
//fileIn.nextLine();
price_three = fileIn.nextDouble();

I'm having problems accessing the total price I initialized inside my if else statements

How can I get the sum of the three Total prices inside the if else statements for red velvet, buttercream and vanilla? And display it in allTextArea text area?
Here's my code:
double redVelvetPrice = 4.00;
double buttercreamPrice = 7.00;
double vanillaPrice = 3.00;
double firstHalf = 6.00;
double firstDozen = 12.00;
double firstBox = 25;
double secondHalf = 6.00;
double secondDozen = 12.00;
double secondBox = 25;
double thirdHalf = 6.00;
double thirdDozen = 12.00;
double thirdBox = 25;
String s1 = "";
String s2 = "The flavors you selected is/are: \n";
String s3 = "";
String s4 = "";
String s5 = "";
String totalPrice = "";
if (redVelvetCB.isSelected()){
s1=s1+ " "+ redVelvetCB.getText() + '\n';
if (firstHalfRB.isSelected()){
s3 ="A " + firstHalfRB.getText() + " of Red Velvet Cupcakes\n = $" + redVelvetPrice * firstHalf + '\n' + '\n';
}
else if (firstDozenRB.isSelected()){
s3 =firstDozenRB.getText() + " of Red Velvet Cupcakes\n = $" + redVelvetPrice * firstDozen + '\n' + '\n';
}
else if (firstBoxRB.isSelected()){
s3 =firstBoxRB.getText() + " of Red Velvet Cupcakes\n = $" + redVelvetPrice * firstBox + '\n' + '\n';
}
}
if (buttercreamCB.isSelected()){
s1=s1+ " "+ buttercreamCB.getText() + '\n';
if (secondHalfRB.isSelected()){
s4 ="A " + secondHalfRB.getText() + " of Buttercream Cupcakes\n = $" + buttercreamPrice * secondHalf + '\n' + '\n';
}
else if (secondDozenRB.isSelected()){
s4 =secondDozenRB.getText() + " of Buttercream Cupcakes\n = $" + buttercreamPrice * secondDozen + '\n' + '\n';
}
else if (secondBoxRB.isSelected()){
s4 =secondBoxRB.getText() + " of Buttercream Cupcakes\n = $" + buttercreamPrice * secondBox + '\n' + '\n';
}
}
if (vanillaCB.isSelected()){
s1=s1+ " "+ vanillaCB.getText() + '\n';
if (thirdHalfRB.isSelected()){
s5 ="A " + thirdHalfRB.getText() + " of Vanilla Cupcakes\n = $" + vanillaPrice * thirdHalf + '\n' + '\n';
}
else if (thirdDozenRB.isSelected()){
s5 =thirdDozenRB.getText() + " of Vanilla Cupcakes\n = $" + vanillaPrice * thirdDozen + '\n' + '\n';
}
else if (thirdBoxRB.isSelected()){
s5 =thirdBoxRB.getText() + " of Vanilla Cupcakes\n = $" + vanillaPrice * thirdBox + '\n' + '\n';
}
allTextArea.setText(greeting+s2+"\n"+s1+"\n"+s3+s4+s5+"\nTotal Price is "+totalPrice+".\n"+deliv+payment+bye);
I tried to set the total Price equal to redVelvetPrice + butercreamPrice + vanillaPrice, but the answer would be 14.0 which is the sum of the variables I initialized outside the if else statements (4.00,7.00,3.00),
I want it to be the sum of the prices of the three after selecting the quantity of each flavor. Help me.

You should use an other data type for the totalPrice. It's easier to calculate with numbers than strings.
double totalPrice = 0f;
After that you add up all the different combinations in your if/else statements
if (firstHalfRB.isSelected()){
s3 = "A " + firstHalfRB.getText() + " of Red Velvet Cupcakes\n = $" + redVelvetPrice * firstHalf + "\n\n";
totalPrice += (redVelvetPrice * firstHalf);
}
else if (firstDozenRB.isSelected()){
s3 = firstDozenRB.getText() + " of Red Velvet Cupcakes\n = $" + redVelvetPrice * firstDozen + "\n\n";
totalPrice += (redVelvetPrice * firstDozen);
}
When printing the total in the TextArea you may want to format it so it only has 2 positions after decimal point:
String.format("%.2f", totalPrice);

Java project returning null values

Hi I am new to Java programming. Why are my values returning null after I enter them on the input dialog. I have two classes, one called VehicleApp and the other called VehicleFactory. Help would be appreciated. Thanks.
Full code VehicleApp.java
package romprojectname;
import java.text.NumberFormat;
import javax.swing.JOptionPane;
public class VehicleApp{
public static void main(String[] args) {
String firstname = JOptionPane.showInputDialog("Enter your first name");
String lastname = JOptionPane.showInputDialog("Enter your last name");
long phone = Long.parseLong(JOptionPane.showInputDialog("Enter your phone"));
int nbrVehicles = Integer.parseInt(JOptionPane.showInputDialog("Enter number of vehicles"));
int nbrTanks = Integer.parseInt(JOptionPane.showInputDialog("Enter number of tanks"));
VehicleFactory vehicleObject = new VehicleFactory();
vehicleObject.getSummary();
vehicleObject.HayloFactory(firstname, lastname, phone, nbrVehicles, nbrTanks);
vehicleObject.calcFuelTankCost();
vehicleObject.calcManufacturingCost();
vehicleObject.calcSubtotal();
vehicleObject.calcTax();
vehicleObject.calcTotal();
}
}
Full code VehicleFactory.java
package romprojectname;
import java.text.NumberFormat;
import javax.swing.JOptionPane;
public class VehicleFactory{
private String firstname;
private String lastname;
private Long phone;
private int nbrVehicles =0;
private int nbrTanks =0;
private double manufactureCost =0;
private double fuelTankCost =0;
private double subtotal =0;
private double tax =0;
private double total = 0;
private final double VEHICLE_PRICE = 500.19;
private final double FUELCELL_PRICE = 2.15;
private final int CELLS_PER_TANK = 12;
private final double taxrate = 7.25 / 100 ;
public void HayloFactory(String firstname, String lastname, Long phone, int nbrVehicles, int nbrTanks){
this.firstname = firstname;
this.lastname = lastname;
this.phone = phone;
this.nbrVehicles = nbrVehicles;
this.nbrTanks = nbrTanks;
}
public void calcManufacturingCost(){
double manufactureCost = nbrVehicles * VEHICLE_PRICE;
}
public void calcFuelTankCost(){
double fuelTankCost = nbrVehicles * nbrTanks * CELLS_PER_TANK * FUELCELL_PRICE;
}
public void calcSubtotal(){
double subtotal = manufactureCost + fuelTankCost;
}
public void calcTax(){
double tax = subtotal * taxrate;
}
public void calcTotal(){
double total = subtotal + tax;
}
NumberFormat cf = NumberFormat.getCurrencyInstance();
public void getSummary(){
String summary = "WELCOME TO HAYLO MANUFACTURING" + "\n" + "\n";
summary += "Customer Name: " + firstname + " " + lastname + "\n";
summary += "Customer Phone: " + phone + "\n";
summary += "Number of Vehicles: " + nbrVehicles + "\n";
summary += "Number of Tanks: " + nbrTanks + "\n";
summary += "Vehicle Cost ($500.19 / vehicle): " + cf.format(manufactureCost) + "\n";
summary += "Tanks Cost ($2.15 / fuel cell): " + cf.format(fuelTankCost) + "\n";
summary += "Subtotal: " + cf.format(subtotal) + "\n";
summary += "Tax (7.25%): " + cf.format(tax) + "\n";
summary += "Total: " + cf.format(total) + "\n";
//display the summary
JOptionPane.showMessageDialog(null, summary);
}
}
Problem (code taken from VehicleFactory.java)
All of the summaries such as customer name are returning null values and all the costs and totals are $0.00.
public void getSummary(){
String summary = "WELCOME TO HAYLO MANUFACTURING" + "\n" + "\n";
summary += "Customer Name: " + firstname + " " + lastname + "\n";
summary += "Customer Phone: " + phone + "\n";
summary += "Number of Vehicles: " + nbrVehicles + "\n";
summary += "Number of Tanks: " + nbrTanks + "\n";
summary += "Vehicle Cost ($500.19 / vehicle): " + cf.format(manufactureCost) + "\n";
summary += "Tanks Cost ($2.15 / fuel cell): " + cf.format(fuelTankCost) + "\n";
summary += "Subtotal: " + cf.format(subtotal) + "\n";
summary += "Tax (7.25%): " + cf.format(tax) + "\n";
summary += "Total: " + cf.format(total) + "\n";
//display the summary
JOptionPane.showMessageDialog(null, summary);

You haven't really described the problem, but I suspect this is the cause:
VehicleFactory vehicleObject = new VehicleFactory();
vehicleObject.getSummary();
vehicleObject.HayloFactory(firstname, lastname, phone, nbrVehicles, nbrTanks);
You're calling getSummary before you call HayloFactory - so it's trying to display the values in the object before you've set them to useful values.
Additionally, all your calcXyz methods are introducing new local variables, like this:
public void calcTotal(){
double total = subtotal + tax;
}
Instead, they should be setting the field values:
public void calcTotal(){
total = subtotal + tax;
}
If you change all of your calculation methods appropriately, then move the getSummary() call to the very end, it will work. (It's not quite how I'd have written the code, but that's a different matter.)

The variables defined insides your methods have local scope only for example
double manufactureCost = nbrVehicles * VEHICLE_PRICE; it actually hides your class variable manufactureCost .. they should be instead used as
manufactureCost = nbrVehicles * VEHICLE_PRICE;
This way you can actually set the class variable which in turn displayed inside your getSummary method

After the login class was successfully accessed, it does not continue to the main method. I don't know what codes are needed to manipulate to connect the login class to the main class. Thanks for those who will help! :)

Remove the main method from you login class:
public static void main(String[] args) {
MILogin milogin = new MILogin();
milogin.run();
}
Then instance the MILogin class from your Main Class:
MILogin milogin = new MILogin();
milogin.run();
