Your sales associates need a program where they can enter customer information and calculate the customer's total bill. When the sales associate enters the program they should be presented with this main menu.
Enter customer information
Display Total Bill
Quit
If the sales associate selects option 1, the program should allow the sales associate to input their name, address, and e-mail address. Your program should then display this customer information to the screen with a message that the customer has been added to the customer list.
If the sales associate selects option 2, the program should ask the sales associate for the customer's name, product that the customer is purchasing, the quantity, and the price of the product. The total bill will then be displayed to the screen and should include the following:
- The customer's name.
- The product the customer is purchasing, the quantity, and total cost
- The amount of tax 8%
- The total cost with tax.
Example Total Bill Output:
John Doe
Product Purchased Quantity Total Cost
Shoes 2 $100.00
Tax 8%: $8.00
Total Cost: $108.00
This is the code that I need to do without using the Joptionpane:
An Internet service provider has three different subscription packages for its customers:
Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour.
Package B: For $13.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour.
Package C: For $19.95 per month unlimited access is provided.
Write a program that calculates a customer's monthly bill. It should ask the user to enter the letter of the package the customer has purchased (A, B, or C) and the number of hours that were used. It should then display the total charges.
This is what I have so far : Cannot use Joptionpaneshowinputdialog

I'm struggling with inheritance in my assignment. The assignment states that I should use the calculatePrice() to calculate the total price and use another method to display the total. The I must overload the calculatePrice() and add a fee in the SpeedOrder() class.
My main class
package useorder; import javax.swing.*; public class UseOrder { /** * @param args the command line arguments */ public static void main(String[] args) { Order.display();
[Code] .....
The problem is mainly displaying the TotalPrice field and. I can't display TotalPrice if it's not static but if it's static I can't inherit it to the SpeedOrder class to assign the total in the overloaded calculateprice method. How can I display the total in my order class and use it in my SpeedOrder class?
write a program that calculates the change due to a customer by denomination; that is, how many pennies, nickels, dimes, etc. are needed in change. The input is to be purchase price and the size of the bill tendered by the customer($100, $50, $20, $10, $5, $1).
import java.util.Scanner; public class Bill { public static void main(String[] args) { Scanner console = new Scanner(System.in); //final variables Premium Service final double monthlyChargeP = 25.00; final double FordayminutesP = 0.10;

A shopkeeper in Diagon Alley needs you to write a program that will calculate the correct amount of change due to a customer. (In Diagon Alley they use three coins with different values, given below).
1. Prompt the user to input the amount of sale in Galleons, Sickles, and Knuts.
2. Prompt the user to input the amount of money given by the customer in Galleons, Sickles, and Knuts.
3. Create constants that represent:
a. 1 Galleon = 17 Sickles
b. 1 Sickle = 29 Knuts
4. Perform the necessary calculations and conversions to compute the correct change in the least number of coins.
5. create a formatted receipt recording the entire transaction.
Here are what is steps 1 and 2 and 5 but problem with are 3 and 4. I need to create the constants and use proper conversions to give the right amount of change back.
Java Code:
import java.util.Scanner; public class OperatorFormatting { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Welcome to Flourish and Blotts");
[Code] ....
Basically, on steps 3 and 4 which are creating the constants and using the to make the proper conversions to give the customer the proper amount of change Due.
Write a program that will calculate the cost of a ticket order and display the receipt for the customer on the screen. There are 2 ticket prices: adult, and senior citizen. Adult seats are $4.50 and senior citizen seats are $3.50. If more than 5 senior citizen tickets are purchased, the customer gets an extra 20% off the of the ticket order. If more than 10 regular seats are purchased, the customer gets an additional 10% off the cost of the order. A customer can only place an order for one type of ticket. Output the type of ticket purchased, the number of tickets purchased, the gross cost, the amount of the discount, and the final cost of the order.

I wanted to write a simple code that receives information from the user (double-digit number and above) and calculates it's numbers.
For instance- The user wrote a number- 234, the software will return the number 9 (2+3+4 = 9).
Tried to use a loop for that, but I got stuck since I didn't know what to write.
This is what I've wrote so far
Java Code:
import java.util.Scanner; public class Calculate { public static void main(String[] args) { System.out.println("Please type a number larger than 9"); Scanner type = new Scanner(System.in); String number1 = type.nextLine();
for( int i = 0; i < number1.length(); i++ ){ int calculate = number1.charAt(i); } } } mh_sh_highlight_all('java');
I work for my local probate court, and one service we offer is email reminders. They fill out a form, it's entered in the system, and they will be notified when something is due. I've been allowed to create a program that will allow me to enter the information from the form to keep track of the attorney's who have signed up.
public class Attempt1 { public static void setConnection() throws SQLException { Connection conn = null; Statement state = null;

The issue I have is the method setQuery. It displays a table with the data entered. Where it currently sits at line 21, it does not display the table, nor does it seem to terminate the program. The goal was to update the table with a few entries, and then display the Jtable. When placed above the setInsert method, it displays just fine, and will reflect the new entries added the next time you start it. I'm still learning Java outside of a classroom environment on my own, so I can only imagine that this is riddled with poor coding, but I just can't seem to figure out why it doesn't display the table after the setInsert method is called. In it's current state, this program is just meant to test functions of SQLite with Java. From there it will be created with a GUI.
I was wondering how can I calculate total age in months and store it as variable? this is what I have so far:
* * You will ask the user to provide their name (as a single word, assume first name here) * You will ask the user their age in full years (no fraction or months) * You will ask the user how many full months since their last birthday (again, whole numbers here). * * You will use this information to calculate the user's age in months and use that information to print out a greeting. */ import java.util.Scanner;
I am making a shopping cart web, but some problems I meet about how to calculate the total price
I use ajax in product list web and if I choose one product , it will send the Id that I read from MySql to servlet and use session to save it . and I click the button jump to the cart, the page cart.jsp will read information from session ,and find product information from mysql by id , now my question is where I calculate the total price, servlet or jsp?
So basically, I've been trying to create a for loop that asks the user for a number between 1 and 30, then calculates the total of the series of numbers. For example, if 15 is entered, the calculation should be 1/15+2/14+3/13+...15/1 which would equal approximately 38.1. The problem I'm having is that the code doesn't loop whenever I type a number for some reason, which results in a very incorrect calculation. Here is my code so far:
import java.util.Scanner; public class HmwLoop { public static void main(String[] args) { double sum = 0; for (double num1 = 1, num2 = 30; num1 <= 30 && num2 >= 1; num1++, num2--)
The pay rate is php 35.00 per hour. any hours worked after 40 hours is paid at rate of 2 times the normal hourly rate. Calculate and display the Normal Pay, The overtime pay, and the total pay.
OUTPUT MUST BE:
Sample 1 :
Enter Hours Worked: 40 (Sample) Normal Pay: 1400 (Sample) Overtime Pay: 0 (Sample) Total Pay: 1400 (Sample)
Sample 2 :
Enter Hours Worked: 41 (Sample) Normal Pay: 1400 (Sample) Overtime Pay: 70 (Sample) Total Pay: 1470 (Sample)
Here is my code or something, but i cant finish it.
import java.util.Scanner; public class Workpay { public static void main(String[]args) { Scanner in = new Scanner (System.in); int hours; int normalpay = 35;
This is what I've tried so far. What i want to do is to calculate all Total Amounts by adding all the rows (5th column only),as 5th column has total amount for 1 product, and set the text for a JTextField whenever the 5th column of any row changes its value.But this isn't working my way. I have also tried keyListener to trigger that change at Enter key typed but that also don't work for me.
So I've attempted a for loop for this type of problem:If you receive $0.01 on the first day of your allowance, and the daily rate doubles each day after, calculate the total earnings for 30 days.
Output should be like: Day ----- Daily allowance - Total allowance 1 -------- 0.01 -------------- 0.01 2 -------- 0.02 -------------- 0.03 3 -------- 0.04 -------------- 0.07
My code so far:
public class Allowance { public static void main (String[] args) { int day = 0; double daily = 0.0; double total = 0.1; System.out.println("Day Daily Allowance Total Allowance"); for(day = 0; day <= 30; )
I have an assignment to create a JFrame pizzaorder and at the end of this order after the totalprice is calculated I need to format the number to ##.## but I keep getting a cannot find symbol error.
Source Code:

So I have a class called Team that is a collection of players and managers for a baseball team, and one of my required methods is to calculate the total amount of Home Runs hit by the batters. Now along with the Team class I have an abstract Employee class, an abstract Player class and a Batter class that extends the Player class I thought this would be fairly easy but it is coming out to be pretty hard my code is as follow:
class Team { public int _numPitcher; public int _numBatter; public String _manager; public ArrayList<Player> team;
[Code] ....
The total salary works awesome but for some reason when I try and call up how many home runs a player has it wont call correctly I get this red line under my code that says: The method getHomeRuns() is undefined for type Player. I am trying to call this from the batter class which is an extension of the Player class...
I'm trying to create a GUI application that calculates and displays the total cost for certain automotive maintenance services. The application should contain hree classes: 1) the main class that creates and displays the window; 2) a panel for the routine services and 3) a panel for the non-routine services. 2 and 3 are instantiated in 1. I'm pretty positive the error lies in the NonRoutinePanel class because when I comment it out of the main class the program runs fine. But I can't quite figure out which lines of code or methods are causing the problem.
When I try running the program I get these error messages:
Exception in thread "main" java.lang.NullPointerException at java.awt.Container.addImpl(Container.java:1040) at java.awt.Container.add(Container.java:958) at javax.swing.JFrame.addImpl(JFrame.java:540) at java.awt.Container.add(Container.java:926) at JoesAutomotiveGUI.<init>(JoesAutomotiveGUI.java:38) at JoesAutomotiveGUI.main(JoesAutomotiveGUI.java:111)
Here's my code for the three classes:
import javax.swing.*; // Needed for Swing class import java.awt.*; // Needed for BorderLayout class public class RoutineMaintenancePanel extends JPanel { public final double oilChange = 26.00;// cost of oil change public final double lubeJob = 18.00;// cost of lube job

How do you use power of math. I'm trying to write a calculator to calculate the volume of a cylinder by asking the user to enter the height and radius but when I use pow(2) it doesn't work. I imported java.lang.math class so i dont have to keep using math. for now my code runs just fine since I'm using radius * radius but I would really luv to use the power instead times each other when i have to use higher powers.
import java.util.Scanner; import static java.lang.Math.*; public class Lab2 { public static void main(String[] args) { Scanner scan = new Scanner(System.in);
