So far this is the code I have. It will successfully read the contents of the file(which are below in quotations) and write them to the designated file. My issue is totaling the corresponding costs to their services and then writing that to the file. The if and else if clauses above do not work but how is it that I can get them working?

I am trying to display two types of table one with initial cost and another one with new cost. Based on the java code here i already have one table but don't know how to display another table.
Attached is the sample output that i am aiming for. The output table for the above code is:
Enter the number of vertices
6
Enter the adjacency matrix
0 4 0 0 -1 0
0 0 -1 0 -2 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 -5 0 3
0 0 0 0 0 0
Enter the source vertex
1
distance of source 1 to 1 is 0
distance of source 1 to 2 is 4
distance of source 1 to 3 is 3
distance of source 1 to 4 is -6
distance of source 1 to 5 is -1
distance of source 1 to 6 is 2

I'm doing a program where a user enters in exam results for students. Once he's entered the code, the code should split the results in stars in 4 categories.
I am working with a while loop that prints out infinite results. What I want to do is, if the user enters 2 digits, say "12", it should output 1 "*".
If the user enters "21" and "22", it should output "**".
There are 4 categories of marks which are marked with ints range1, range2, range3 and range4, which are user enter digits. Part 1 of the code is to split the user entered digits into its correct ranges. the ranges are 0-29, 30-39, 40-69 and 70-100. I've done the part where when the user enters a digit, it goes into the correct variable. After that when the user enters a digit over 100, the enter results should show up as stars. For example
Enter number =
21
22
44
66
44
23
11
111 (the 111 is where the program breaks and moves on)
So it should then display
0-29 ****
30-39
40-69 ***
70-100
Whatever I'm trying, it displays an infinite amount of stars. If I try to use break, It only outputs a single star, no matter how many digits I enter
Here is the code
int mark = 0;
int range1 = 0, range2 = 0, range3 = 0, range4 = 0;
int count1 = 0, count2 = 0, count3 = 0, count4 = 0;
while (mark >=0 && mark <=100) {
[Code] .....
"The problem is with the while loop, the one above is something I was experimenting with "

This is supposed to get a certain number of items, and then calculate how much every item costs. It adds up the sum of those prices and checks if it is over 150$, if it is, it returns true, if it's not, it returns false.
import java.util.*;
class Cust
{
public static boolean DelPay (int a) {
Scanner reader=new Scanner (System.in);
int b,s=0;
for (int i=1;i<=a;i++) {
b=reader.nextInt();
s=s+b;
}
if (s>150)
return true;
return false;

So I have created a array list of pizza toppings, only 4 in total, and each ingredient needs to have a cost property. I'm supposed to access the cost through a get / set method, as the user can create their own pizza and it will total up the cost, but how to.

I am new to java and this is one of my first program assignments. I can't figure out how to make the if else statements work. I am trying to get the input from the user to be multiplied by the package cost but it gives me an error. I also can't figure out how to solve for the discounted total.
Purpose of the program: To write a program that asks the user to enter the number of packages purchased. The program should then display the amount without any discount, the amount of the calculated discount (if any), and the total amount of the purchase after the discount is applied.
What the output should be:
Enter the number of packages purchased: 10
Your total without discount: $990.00
The discount is: $198.00
The discounted total: $792.00
import java.util.Scanner;
public class Practice {
public static void main(String[] args) {
double packageCost = 99.00;
double amtPackage = 10.00;
double withoutDiscount = packageCost * (double) amtPackage;

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.

A wages calculator application is required that can determine the total cost of crew departing from the port on that day. To do this, the application reads from an itinerary text file containing each ship being loaded in the port that day, in the following format:
<ship id>
<journey id>
<l> // where <l> is the length in hours of the journey
<s> // where <s> is the number of crew for the ship for this journey
<rate> // for each s, <rate> is hourly rate of pay
Your application must calculate the total cost of the crew for each ship/journey and then compare it with a "recommended maximum journey cost" (RM) amount typed in by the user when the application is first run. If the total amount is less than or equal to RM then the details must be written to the screen and to an output text file called wagedaily.txt. If the amount is larger than RM then the results must be written to the screen only. Messages to the screen must indicate whether the crew cost is less than, equal to or larger than RM.
Your application should find the ship with the highest crew cost that is below RM and print this out as the final piece of output to the screen.
It has given me a bunch of ships and numbers to play around with in the code, here they are:
Monarch
M141
16
6
10.5

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 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

This program is for a swimming pool filling service company. They charge 2 cents per gallon and $50 per hour to fill a pool. The truck can fill at a rate of 730 gallons per hour.
Create the Pool class that calculates the cost to fill a pool based on it's Shape, length, width and depth. (Input order is S L W D)
The pool class will need data fields for String shape, double length, double width, double depth, static double GallonsPerSqFoot = 7.4805, static double price per gallon = .02, static double FillingFeePerHour = 50.0, and static double FillingRate = 730gal/hr.
Create a No-Arg constructor and a constructor that accepts the non-static values, and has the methods: getShape, getLength, getWidth, getDepth, getGallons, getHours, getFillingFeePerHour, getHourlyCost and getTotalCost.
At the end of the class, create a main() method that asks for the input and returns the output based on the Pool class gets.. methods.
The shape options are oblong or rectangle. (A round pool would be oblong with the same width and height, a square pool would have the same width and height)
Formulas:
Rectangle cubic ft = length * width * depth.
Oblong cubic ft= ((Math.PI * Math.pow(width/2,2)* depth) +((length-width) * width * depth))
Gallons = cubic ft * 7.4805.
hours = total gallons/730.
Total cost = (total Gallons * .02)+(hours * $50)
Example Output
An oblong pool 18.00 feet long by 12.00 feet wide and 5.00 feet deep will use 6923.10 gallons of water and take 9.48 hours to fill. The total cost will be 612.65.
Here is my code:
import java.util.Scanner;
import java.util.*;
public class Pool
{
private String poolshape1 = "oblong";
private String poolshape1 = "rectangle";
private double length;
private double width;
private double depth;

I'm new to Web Services and I've been finding trouble when creating my first one. Before talking about the problem, I'd like to show you the process I followed to see if it's ok. Note that I'm using Eclipse Kepler, Tomcat 5.5 and Axis2.
1- I created a new Dynamic Web Project.
2- I created the Java class that implements the service with just one method, a simple one: you pass it a name and it returns "Hi, <name>"
3- Right click over that class and then: Web Services -> Create Web Service
4- I go through the next steps. On the last one, I select "Launch the Web Services Explorer to publish this Web service to a UDDI Registry". Click on "Finish".
5- The Web Services Explorer is launched, but I just get a "HTTP ERROR: 500" message.
I understand that my Web Service wasn't published and therefore it's useless to create a client as it wouldn't connect.

I have a server with a handful of php services. I communicate with these services by creating connections from java code. The services currently respond with XML, but that can be changed if an alternative way can improve performance.
One of the things I need to do is send varying sized payload (some large) to one of the services. My current plan is to create an xml file in java and perform a POST request with the XML as the payload. I am using an XML because the data is very structured.
From a performance point of view, would it be better to send the XML as a file or just as text? Also, is there a better way to send this data? These services will eventually be used by an android app, where performance and minimizing the size of the data packages will be extremely important.

I need to write a simple client to access a WS. Things I can not do :
Modify the serverAdd external jars
The client will be part of a command line call and will run as a stand alone.
I've been searching all day and have found hundreds of vague, overly complex examples, mostly based on SOAPHandler (which tells me I need to install server components which I cannot do). I grasp the general requirements but am having difficulty figuring out how to add the security elements to the header.
What do I need to do to add the username and password tokens to the header?
This is where I am so far.
