Calculate Cost Of Ticket Order And Display Receipt For Customer On Screen
Oct 4, 2014
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'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

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 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?

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.

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;

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

import java.util.Scanner;
/**
This program demonstrates a switch statement.
*/
public static void main(String[] args)

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;
private static double GallonsPerSqFoot = 7.4805;

The intent of the code is to read date from a file, does calculation and then displays that data in a table format on the screen. Then creates another file with those values:
Reads file: Beginningbalance.txt
Displays Data with calculation
Creates a file called "Newbalance.txt" with the following values:
111
251.41
222
402.00
With the way the code is written I can get it to create the file but it only displays one of the customers (111). I know that I need to create a loop but I am not sure how to build that. I tried creating another while loop and changing it to outFile but that was without success.

I am writing a piece of software to display an image on the screen using a particular library. The library lets me create an Atlas out of texture file data, to fetch Textures out of the Atlas using the textures' names, and to draw the textures by calling Renderer.draw(texture). It doesn't make a great deal of sense to create more than one of an Atlas or Renderer. I previously designed my code as follows:
public class SystemAssets {
static Atlas atlas;
public static void initializeAtlas(String pathToTextureFiles) {
atlas = new Atlas(pathToTextureFiles);
}
public static Texture getTexture(String textureName) {
return atlas.getTexture(textureName);
}
}
Similarly, I made a TextureRenderer class whose sole purpose is to provide static access to a Renderer. But many people seem to say that opening up a class like this to global access is bad. I cannot think of any better alternative, however. My core update/draw logic currently works something like this:
public class Game extends AbstractGame {
public void init() {
Screen current = new FirstScreen();
TextureRenderer.initialize();
[code]...
Making a Renderer object belong to the Game or Screen class doesn't make much sense to me, as there doesn't seem to really be a 'has-a' relationship between them; it's more of a 'uses-a', so that seems to imply that it would be best to just call Renderer.draw(thing) from outside the class rather than making it a data member. This would make my main code essentially call the various methods in order to get or print some form of data, much like System.out.println(). And of course, making one of the classes a subclass of Renderer makes even less sense. But making data members static for the purpose of global access and using singletons are often cited as 'bad' programming practices. This problem also arises in a lot of other scenarios in my program, ie. when I want to serialize Thing data members like texture filenames; do I put the serializer as a static data member in a class for global access and call it like I would a function, or do I put it in a class? And it seems like the Renderer will have to be initialized at the start of the program, which would take place in the init() method in Game, then be used to draw Textures in the Screen, so it would have to be accessible from both locations.
edit: In case it's suggested to put these in the main class, that's unfortunately going to be difficult without using static variables; the library recommends having the main class creating an Application object, which is essentially a black box that actually does all the work of calling Game's init() and draw() methods (via a Game object passed into its constructor) and looping until the program exits. AbstractGame and Screen are classes supplied by the library, so it doesn't seem like I can easily give Game any data that AbstractGame doesn't specifically ask for.

Write a program that will read two numbers and an integer code from the keyboard. The value of the integer code should 1, 2, 3, 4. If the value of the code is 1, compute the sum of the two numbers. If the code is 2, compute the difference (first number minus second). If the code is 3, compute the product of the two numbers. If the code is 4, and the second number is zero, compute the quotient (first divided by second). If the code is not equal to 1,2,3,4, display an error message. The program is then to display two numbers, the integer code and the computed result to the screen
here is the code that I have so far:
public static void main(String[] args) {
Scanner read = new Scanner (System.in);
int num1, num2, code, sum;
System.out.println("Please enter a number");
num1 = read.nextInt();

Create a class that allows the user to select a file and output the contents of the file to the console. Recommend using a text file to display, java files are text files. You may want to put this code in a method to allow you to complete the remainder of this assignment without overwriting your code.
- You should ask the user to enter the full path to your file to make certain you are processing the correct file.
- Modify your code/add a method to display the contents of the file in reverse order. You do not need to reverse the characters on each line but simply output the lines of the file in reverse order.
Hint: read the content of the file into an ArrayList and then traverse the ArrayList.
this is what i go so far.
package classActivity;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.Collections;
