my project is to design a class that stores the number of units sold and has a method that returns the total cost of the purchase..the given info is unit are $99. discounts are 20% for 10-19 units; 30% for 20-49 units; 40% for 50-99 units; and 50% for 100 or more units purchased... When i run the code and put in the units sold it returns: 0 units sold, $0.00 cost, 0% discount. How do I get the output to actually do the equation and give proper information. We were given a demo file from the instructor and had to create a class that works with it first set of code is the demo file:
package chapter4;
import java.text.DecimalFormat;
import java.util.Scanner;
/**
* SoftwareSalesDemo Program
*/
public class SoftwareSalesDemo {
public static void main(String[] args) {
int units; // To hold units sold
i have to ask user gross sales until -1 sentinial and to get the commission to put in groups its 9% times the sales add $200 the groups are formatted a) $200-299 /> $300-399 .... i) $1000 and over
import java.util.Scanner; public class Commissions { /** * @param args
Design a program that will read a file of sales records and produce a sales report. Each record in the file contains a customer's ID, name, a sales amount, and a validated GST code. The GST code is to be applied to the sales amount to determine the sales tax due for that sale, as shown below.
GST CodeGST Rate 0 1 20% 5% 10%
The report is to print a heading "SALES REPORT", and detail lines listing the customer's ID, name, sales amount, sales tax, and total amount due including sales tax.

How would I get my program to display a * for every 100 dollars in sales that the user enters in so: for example the user enters in store 1: $ 400 in sales for the store I want it to display store 1:****
The first part of my code allows the user to enter in whatever values the stores have in sales. The Second half of the code starts at line 19 is my best guess on what I need to do I just am not sure how to get it to display what I need it to.
The manager of a football stadium wants you to write a program that calculates the total ticket sales after each game. There are four types of tickets: box, sideline, premium, and general admission. After each game, the data is stored in a file in the following format:
ticketPrice numberOfTicketsSold
Sample data might look like:
250 5750
100 28000
50 35750
25 18750
The first line indicates that the box ticket price is $250 and that 5750 tickets were sold at that price.
Your program should input in this data (using Scanner or an input dialog box), then output that data to a message dialog box along with total ticket sales information. Output the total number of tickets sold and the total sale amount. Make your output user-friendly and "pretty". Format your output with two decimal places. Use JOptionPane and the formatting techniques learned in chapter 3 for your output. Example output might be:
5750 Box Tickets sold at $250.00 28000 Sideline Tickets sold at $100.00 35750 Premium Tickets sold at $50.00 18750 General Admission tickets sold at $25.00
I have this small program that creates a sales opportunity and its related products, and then prints out the opportunity name, total quantity and total price
class Opportunity{ String name; int Amount; String Stage; int Product_quantity;
[Code] .....
The code works as expected, and is successfully prints :
That said, I feel the way the OpportunityCreator class sums up the quantities and prices (see the comments on the code) is very inefficient, and would only work if there were 3 or less products. How can I design this so that it sums the quantities and prices of all the Product objects that I create, regardless of how many of them are? I understand probably I'd need to redesign the whole thing but I'd like to get at least an idea of how this can be achieved.
Originally I was thinking of creating an ArrayList and adding all the prices/quantities there but wasn't sure how to do. I also thought of using a loop to loop through the different object references and sum the quantity/price but was also unsure on how to do so?
I am working on trying to show the average daily sales for the store. I cannot quite figure out why my calculation is not working. Everything works except my average sales is always $0.00... lines 185-189 is where my calculation is located.
Java Code:
import java.util.*; import java.text.*; import javax.swing.JOptionPane; /******************************************************************************* * Create a fancy class for a cash register. *******************************************************************************/ public class fancyRegister{ /** current amount due */ private double currentAmount;
gather sales amount for the week display the total of sales display the average of sale display the highest sale amount display the lowest sale amount
using occurrences determine how many times the amount occurred for the week
make a sales main make a sales data
This is what i have so far but I'm confused on how to start the occurrence and where it would be placed in order to get the information from the array
public class SalesData { private double[] sales; // The sales data /** The constructor copies the elements in an array to the sales array. @param s The array to copy. */ public SalesData(double[] s) {
I'm writing this super simple code as I follow along in this java textbook, and I don't know why it's giving me an error in my tester program!
CashRegister.java
public class CashRegister //a cash register totals up sales and computes change due { private double purchase; private double payment; /**establishes instance variables "purchase" and "payment" and assigns them as doubles to store the two amounts later on. the assignment as private makes it so ONLY methods in this class can access these instance variables*/
This specific assignment requires me to write a program that calculates the total sales after each football game. There are 4 types of tickets: box, sideline, premium, and general admission. After each game, data is stored in a file... then output the number of tickets sold and total sale amount. Format your output with 2 decimal places.
Okay I know there is a I/O section and wasnt sure where to post this. I need some insight on how to use file input and output as well ... Here is my program:
import javax.swing.JOptionPane; import java.text.DecimalFormat; public class ticketsSold { public static void main(String[] args) { String BoxSeat; String SideLine;

In a project for school. I have a program that links several GUI's as a menu based program. What I am trying to accomplish is when one of the previous GUI's is closed that it doesn't terminate the entire program. There is a lot of classes in the entire project so I'd prefer not to paste all the code here, but if it is necessary I will do so.
I'm creating a program that will compile and run another java program:Lets say I have a program in directory
D:HelloWorldsrc and compiled program will be in D:HelloWorldin inside src and bin is a folder hello (that's a package)
package hello; public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World"); System.out.println("Hello World"); } }
This program will be run by another program (that's the program that I am creating).Here is the code of my program:
package runnercompiler; import java.io.IOException; import java.io.InputStream; import java.util.logging.Level; import java.util.logging.Logger; public final class RunnerCompiler {
I'm working in a GUI program, but I'm not going to put the code because there is a lot of code and files. Instead, I will try to put it an example.
Let say:
I'm working in a GUI program that ask form the user to enter two number's. When the user press at the calculate button. It will show up the output. However, the program won't exit unless the user press at red (X).
int x = user_Input1; int y = user_Input2; int total = x + y; // JOptionPane.showMessageDialog(null, total);
I know that there will be a (total) now, so my question is here how can I reset all the calculation and have a new total that will show up when the user enter two number's again.
I have searched the internet for about 2 days and now i'm posting this. I'm trying to make a program that will let me enter "1" to show how many movies I have watched and press "2" for a new one. The problem I ran into is I enter 2 then when I enter 1 it said "you have watched 0 movies". I know what the problem is I just don't know how to retype it. here is the code.
package stuff; import java.util.*; public class thing {
I just finished a tutorial on youtube that covers the basic java, and now i want to try and make a game / program thing, only problem is that i have never worked with graphics before (i have tried to make ovals, rectangles, and other things with the paint method tho )
I know how to make a jframe and a jpanel, and i feel like i can make a simple "game" (not a complicated one, just a simple one with a guy walking around on the screen) in fact i have already make a such game, where you are a oval walking around on the screen, so thats not really my problem.
My problem is that i want to draw an image on the screen that can walk around instead of the oval, but how to do that. I have made a new project and set up the jframe and jpanel, and my code looks like this:
(main)
import javax.swing.JFrame; public class main_class { public static void main(String[] args){ JFrame f = new JFrame(); f.setTitle("title"); f.setVisible(true); f.setSize(800,600);
[code]...
but once again, i get a blank jframe with no image and no "test" string . How i can display images on the screen?
I am new on this and I will be working in a gpa and average program. This is my code so far: Every time that I try to add the gpa part it gives me errors or just duplicates whatever I've in average and displays it in gpa
/** * This program shows a database of students in a school. * It gathers information as name, classes, grades, and calculates average and gpa average. * */ import javax.swing.JOptionPane;
In this exercise you will write a program that estimates the value of π. Pretend that we are looking at a dartboard in the picture above. If the square is 2units wide and 2 units high, the radius of the circle within the square is 1 unit. Then the area of the circle is π*r2 = π*12 = π. The area of the square will be 2*2 = 4.
The estimation of π will work by randomly "throwing darts" at the dartboard. We will assume that every dart will hit the board but the location of that strike will be random so some darts will land inside the circle and some will land outside the circle. The calculation of π is then the ratio of the number of darts that land inside the circle to the total number of darts, multiplied by 4. Note that as we increase the number of darts used in the simulation, the accuracy improves.
Follow the steps to complete the program:
1.Declare variables that represent x, y coordinates of a dart, the distance of the dart from the origin, the number of darts that land inside the circle, and the total number of darts.
2.Read in the total number of darts (N) from the user and create an instance of the Random class.
3.Create a loop that runs N times. Inside the loop, you will use the nextFloat() method of the Random class to create x, y coordinates randomly, and then compute the distance of the dart from the origin. Determine whether the dart lands inside or outside of the circle.
4.Compute π using the estimation algorithm.
5.Run the program with increasing numbers from 100 to 100,000,000 and observe the accuracy of π.
