How To Add Customer Class
Jun 24, 2014
-A customer has a name, an email address and a list of supplements which they are interested in.
-A paying customer has a payment method and a list of associate customers whom they also pay for.
-An associate customer is a customer whose subscription is paid for by a specified paying customer.
-A payment method could be by a specified credit card or direct debit from a specified bank account.
-A supplement has a name and a weekly cost.
The magazine also has a weekly cost for the main part.Each week, each customer gets an email telling them their magazine is ready to look at and listing the supplements that they currently subscribe to.Each month, each paying customer gets an email telling them how much is being charged to their card or account for the month and itemizing the cost by supplements for them and any of their associate customers.Design and implement enough functionality in the classes to allow the operation of the following test program (which you also design, implement, test, and document):The client program should do the following:
a) construct a magazine with an array of 3-4 supplements with made-up details built in to the program (Alternatively, get input from the user using the Java Scanner class),
b) construct an array of 5-6 different customers of various types with made-up details built in to the program (Alternatively, get input from the user using the Java Scanner class),
c) view details of all customers stored in the array,
d) print out the text of all the emails for all customers for one week of magazines,
e) print out the text for the end of month emails for the paying customers,
f) add a new customer to the magazine service,
g) remove an existing customer from the magazine service.
Display enough information during the running of the program to allow checking of its operation.

Here is my current code. The CustomerName in the System.out.print statement doesn't compile - it says that CustomerName can not be resolved to a variable. But why is that true? it is declared and assigned a value in the for loop.
Query query = em.createQuery("select CustomerName from web_cost_file,customer " +
"where web_cost_file.customer=customer.id and web_cost_file.customer=" +
costsFileList[0]);
List<Object[]> listCustomerName = query.getResultList();
for (Object[] result : listCustomerName) {
String CustomerName = result[0].toString();
}
System.out.print(CustomerName);

I have an arrayList with these values:
Mike Smith with a customer id of 100 has an account number of 1000 and a balance of $5,000.00
Hank Jones with a customer id of 101 has an account number of 1001 and a balance of $45,000.00
Sam Overstreet with a customer id of 102 has an account number of 1002 and a balance of $45,000.00
Hank Jones with a customer id of 101 has an account number of 1003 and a balance of $48,000.00
and so on .....
I am trying to do a selection sort by the account holders last name. I understand how to do if the Arraylist holds integers, but my arraylist holds multiple fields. I am not allowed to use collections as this is a homework assignment.
here is the Account Class
public class Account implements Comparable<Account> {
private int acctNum;
private double balance;
private Customer cust; // note we are putting a Customer object in the Account clas
private static int nextAcct = 1000;// used to keep track of the next available account number
[Code] ....

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).

You have a store that sells the following items:
Shoes $50.00
T-shirts $30.00
Shorts $75.00
Caps $15.00
Jackets $100.00
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

Here are the instructions to my assignment:
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 am having errors with incaompatible varriables comparing float with doubles.
public class lab3 {
static Library myLib;
public static void main (String [] args) {
Library myLib = new Library(); //Instance the Library class

What to do with this JAVA code?
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
/* A demonstration of how to use Decision Structures
import java.util.Scanner;
/**
This program demonstrates a switch statement.

public static void main(String[] args)
{

How do you declare methods for a class within the class whilst objects of the class are declared else where?
Say for instance, I have a main class Wall, and another class called Clock, and because they are both GUI based, I want to put a Clock on the Wall, so I have declared an instance object of Clock in the Wall class (Wall extends JFrame, and Clock extends JPanel).
I now want to have methods such as setClock, resetClock in the Clock class, but im having trouble in being able to refer to the Clock object thats been declared in the Wall class.
Is this possible? Or am I trying to do something thats not possible? Or maybe I've missed something really obvious?

Regarding the lifecycle of servlet , in headfirst servlet i can find :
You normally will NOT override the service() method, so the one from HttpServlet will run. The service() method figures out which HTTP method (GET, POST, etc.) is in the request, and invokes the matching doGet() or doPost() method. The doGet() and doPost() inside HttpServlet don’t do anything, so you have to override one or both. This thread dies (or is put back in a Container-managed pool) when service() completes.
How can I call the doGet method of the subclass from the superclass. i am not getting this .

I have a quick polymorphism question. I have a parent class and a sub class that extends the parent class. I then declare an array of parent class but instantiate an index to the sub class using polymorphism. Do I have to have all the same methods in the child class that I do in the parent class? Here is an example of what I mean.
public class ParentClass
{
public ParentClass(....){ }
public String doSomething(){ }
}
public class ChildClass extends ParentClass
{
public ChildClass(....)
[Code] ....
Is polymorphism similar to interfaces where the child class needs all the same methods?

I want to know is there any way we can call parent class method using child class object without using super keyword in class B in the following program like we can do in c++ by using scoop resolution operator
class A{
public void hello(){
System.out.println("hello");
}
}
class B extends A{
public void hello(){
//super.hello();
System.out.println("hello1");

I am working on a program that simulates a bug moving along a horizontal line, My code works correctly when I test it in it's own class but when I tried testing my constructor and methods in a test class I received an error saying, "package stinkBug does not exist" on lines with my methods. However, stinkbug is not a package.

It's showing the error: The method GetInput(float) in the type GetInputFromUser is not applicable for the arguments ()
And when I do: getRadius = ui1.GetInput(rad);
It's showing the error: rad cannot be resolved

I was doing coding exercise from a book ('OCP Java SE 6 - Practice Exams' by Kathy Sierra and Bert Bates). I came to a question that told to demonstrate the difference between 'default' and 'protected' access rules by creating/making a directory structure and putting a couple of classes in different packages.
For this, I made a total of four classes, out of which, three classes are-Car, TestingCars, CarDimensions. (The fourth is not yet used in testing code till now, so, I am giving only the other three classes.) Their coding is given below.
Out of these classes, the classes- TestingCars and Car - are in a directory (say, FolderName). And, the class- CarDimensions is in FolderName's sub-folder.
The class 'CarDimensions' is public (and its components too are public). And, I am testing all the classes from the class- 'TestingCars'. But, this class (TestingCars) is not able to find the public class- 'CarDimensions' which is in its sub-folder and gives two 'Cannot find symbol' errors citing the class-CarDimensions. Also, If all three classes are put in one single directory, the programs work, without any error.
Coding:
Class TestingCars:class TestingCars {
public static void main(String[] args) {
Car c = new Car();
c.setType("FourWheeler");
[Code]....
I could not find why the public class- CarDimensions- is not getting found by the TestingCars class.

I want to write an app that declares a class Person(String name, int age), and an Account class, Account(int code, double balance).But, additionally, every Person has at most 3 accounts, and each account has a Peron associated with it.
my code so far...
public class Person {
private String name;
private int age;
private Account[] accounts;
private int numOfAccounts;
public Person(String name,int age){
this.name=name;
[code]....
My problem is:When I make data input for a person, and additionally I want to read data for the account(s) that this rerson has, what code should I write to create a new Account object as account[numOfAccounts].And, what is the code to assign an owner to a new created Account object?
There exists a relationship between the two classes, but I cannot find the way to implement this relation....
