Three Different Internet Service Provider Packages - Calculate Customer Monthly Bill
Feb 20, 2011
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)
{
char packageLetter;
int hoursUsed;
[Code] ....

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

I want to Write a program that calculates the minimum fixed monthly payment needed in order pay off a credit card balance.
the Amount is 3,500 the annual rate is 9.9%, the minimum payment is 2% a month. the fixed payment is 150.
By a fixed monthly payment, we mean a single number which does not change each month, but instead is a constant amount that will be paid each month.
The program should print out :
payment information:
new balance total .......
current payment due .......
if you make minimum payment (2%) you will pay of in .... months and you Will end up paying an estimated total of $........
if you make the fixed rate payment, you will pay of in .... months and you Will end up paying an estimated total of $........ and you will save $........

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
int ticketNum; //Number of Tickets

I thought there'd be loads of people looking to do the same. I have just got a Github account and uploaded all my source code for a project and would like to upload the associated JAR file with it. I am not too fussed about the JAR file being on github, providing a link to somewhere else it can be downloaded is fine too.

For my job I would to develop a Java application which downloads some data from a webpage and then process them.
The problem is that I have to authenticate to a proxy server to connect to the internet. As I browsed on the net, there is a possible way for implementation.
Authenticator.setDefault(new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
[Code] .....
Sometimes it works fine, but usually I get the following exception:
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required"
at sun.net.www.protocol.http.HttpURLConnection.doTunneling(HttpURLConnection.java:2083)

at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1439)
at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254)
I don't understand what's the problem and why it's not persistent.

I have a click button called log off , here once a user clicks it , task goes to logout servlet to end current user session . below is my code , I don't know why it works fine with mozilla firefox and google chrom but not working with internet explorer.
response.setHeader("Cache-Control","no-store"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0);
HttpSession httpSession = request.getSession();
[Code] ....
here it goes fine to my index, but if I logged in again, I should enter a new session , but unfortunately this not happened in explorer , works fine with mozilla , and chroom.
I have also done in my index.jsp the check like below:
<%
if(session!=null){
session.setAttribute("validUser",null);
session.invalidate();
%>
just to erase whatever previous session . But why session exist on same page ! only in explorer , it makes me open new explorer for new user and that is what I don't want !

I was wondering what happens to the API packages I've imported at compile time. Are they compiled to classes and placed In the same file as the class containing the Import command ?
The reason I'm asking Is because I've noticed the src.zip file Is not In the JRE and since the JRE Is all that's needed to run an app , I'd like to understand what the import command does.

This is for a mortgage calculator and we have to use the math.pow method. I am getting results, but the results are wrong. The monthly payment is coming out to big.
Here is what it should be:
Enter loan amount: 10000
Enter rate: 4.5
Enter number years: 3
The monthly payment is: $297.47
Here is what I'm getting.
Enter loan amount: 10000
Enter rate: 4.5
Enter number years: 3
The monthly payment is: $566.06
Here is my code. I believe my issue is in the math.pow formula.
Scanner in = new Scanner(System.in); // input object
double loanAmount; //user input
double interestRate; // user input
double yearNumber; // user input
double monthlyPayment; // answer to math
double finalPayment; // output
double monthNumber; // year number converted of months
double monthlyRate; // converted intersted rate
[Code] ....
The monthly payment is: $%.2f", monthlyPayment); // Shows monthly payment

-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.

I am doing a program where i have to implement a payroll system into a company for hourly, fixed monthly and commission paid workers. I also have to put the method which i did. the problem is I cant tell if my calculation is wrong or if i am missing a codes some where. The output is not giving me the answer that I was at least expected,
Here is my method:
{
< double total_deduction;>
< total_deduction = gross_pay - deduction;>
< return total_deduction;>
}
< public static double calGrossH(double hours_worked, double pay_rate)>
[Code] .....
I have done a lot researching and have come up with some search with almost the same calculation and I have also asked employees of a company on how they calculated hourly rate, commissions rate and fixed rate for all workers and gotten the same response but for some reason the output is not what it is supposed to output. here is my output.
<
un:>
<please enter the number of employees to be processed 31>
<please enter employee id number 3669>
<please enter employee first name>
[Code] ....
I dont know if I am missing some calculation somewhere or codes been researching and bussing my brains to figure out where is the missing codes or calculation.

Query query = em.createQuery("select CustomerName from web_cost_file,customer " +
"where web_cost_file.customer=customer.id and web_cost_file.customer=" +
