Read File Of Sales Records And Produce Sales Report
Jun 29, 2014
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.

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
{ public static void main (String []args) { Scanner numberin = new Scanner (System.in); double store [];
[Code]....
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.
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 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;
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
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;
The assignment is to create a program that accepts entries from a user for 3 variables then saves the data to a file. There are other programs that use the file created. One program displays the non-default records. The next program allows the user to enter the id for the employee and displays the first and last name for that id number. The last program allows the user to enter a first name. It then displays all id numbers and last names for records with that first name.
Given the above situation, I am stuck on creating the first program. I can make the text file and write the information to it. However, when the file is created, a space is placed in between each entry for some reason. I cannot figure out how to get rid of this space so that I can display the appropriate records for the remaining programs. Below is the code and a view of my problem.
import java.nio.ByteBuffer; import java.nio.channels.FileChannel; import java.nio.file.*; import java.io.*; import static java.nio.file.StandardOpenOption.*; import java.util.*; public class WriteEmployeeList {
[Code] .....
The values for nameFormat and lnameFormat are 10 spaces. This is how the book told me to make sure everything is uniform and searchable. The file contents look like this when viewed in notepad.
I'm having some trouble with getting this program to read an input of morse code and then produce an output of English. When typing in morse code for the phrase 'the string', the output looks something like this:
I am working on a personal project and want to create a text editor to write my code. I am wondering how could I read the last input from the user and if say it was an open curly brace {, then like netbean's my editor will supply the closing curly brace. My java experience is limited but I have tried to read key board input and a few other options that did not work.
I am working on a project and for one step, I need to load an array (which in this case, students[]), with the records in another file.
So, should I used the try, catch method?? I am just not sure about the array. I know how to read from a file, but, I didn't get the idea of loading an array.
So I am calling this method several times and trying to write multiple records to a file. Problem is that every time I call the method it overwrites the file from before and doesn't add it.
public void fileWriterMethod() throws IOException{ RandomAccessFile raf = new RandomAccessFile(filename, "rw"); raf.writeInt(id); raf.writeInt(existingMileage); raf.writeInt(gasCost); raf.writeInt(ndays); raf.writeInt(rate);
I am reading records from a txt file and storing it into an array
import java.util.*; import java.io.*; public class PatientExercise { //patients exercise time public static void main (String[]args) throws IOException{ Scanner in = new Scanner(new FileReader("values.txt")); double [] patientTimeRecords = new double [300]; int noExerciseCount=0, numPatients =0; double highest=0, lowest=0, avg=0, totalTime=0;
[Code] ....
However an error msg keeps popping up:
Exception in thread "main" java.util.NoSuchElementException at java.util.Scanner.throwFor(Scanner.java:907) at java.util.Scanner.next(Scanner.java:1530) at java.util.Scanner.nextDouble(Scanner.java:2456) at pastpapers.PatientExercise.main(PatientExercise.ja va:44)
line 44 is:patientTimeRecords[i]= in.nextDouble();
The basic gist is it's "A program that reads in a text file that uses a specific input format and uses it to produce a formatted report for output."
Specifically :"For this lab you will write a Java program that produces a simple formatted report. The program will prompt the user to enter a file name. This file must contain information in a specific format (detailed below). Each "block" of the file contains information for one player in a competition -- the name of the player followed by a number of different scores that that player achieved. The program should find each player's average score, median score and best and worst scores and display them in a line on the final summary report. The program should also determine which player has the highest average score and which player has the lowest average score."
I get the following errors when I try and compile it:
Enter an input file name: Project11.txt Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException... -1 at java.util.ArrayList.elementData(Unknown Source) at java.util.ArrayList.get(Unknown Source) at Project11.getMedian(Project11.java:68) at Project11.main(Project11.java:27)
I get that the error(s) reside in lines 68 and 27, among problem other areas, but I'm not exactly sure how I can fix them.
Here's my code:
import java.io.*; import java.util.*; public class Project11 { public static void main(String[] args) throws IOException{ Scanner in = new Scanner(System.in); System.out.print("Enter an input file name: "); String input = in.nextLine();
I've got a nasty nullpointer that I have tried to resolve to no avail as of yet. The program should prompt for a listings.txt file and take its info and write to a report file. Here's the stacktrace:
run:
Input file: listings Exception in thread "main" java.lang.NullPointerException at java.io.Writer.<init>(Writer.java:88) at java.io.PrintWriter.<init>(PrintWriter.java:113) at java.io.PrintWriter.<init>(PrintWriter.java:100) at kettask2b.PropertyListingsReport.main(PropertyListingsReport.java:34) Java Result: 1
Some adjustments that I have attempted are:
BufferedWriter pwfo = null; for (int i = 0; i < args.length; i++) { String string = args[i]; pwfo = null;
So I am calling this method several times and trying to write multiple records to a file. Problem is that every time I call the method it overwrites the file from before and doesn't add it.
public void fileWriterMethod() throws IOException{ RandomAccessFile raf = new RandomAccessFile(filename, "rw"); raf.writeInt(id); raf.writeInt(existingMileage); raf.writeInt(gasCost); raf.writeInt(ndays); raf.writeInt(rate); raf.writeInt(totalCharge); raf.writeInt(discount); raf.writeInt(tax); raf.writeInt(netCharge); raf.writeInt(returnMileage); raf.writeBytes(carName + " "); //Closing the stream raf.close(); }
I have written a code to download .csv file with records from DB.
To download records i am uploading a .CSV file containing telephone number.
After downloading the .CSV file page is not getting refreshed.
Below is the code snippet i am using,where i am setting response content type as test/csv.
ServletOutputStream op = resp.getOutputStream(); // Set content type of output resp.setContentType("text/csv"); resp.setHeader("Content-Disposition", "attachment; filename="test""); op.flush(); op.close();
How that page will get refreshed after csv file download or after response.
I am working on a project that requires me to build a database with random access file, representing products, the base product contains a name (about 30 characters), a price (double), and a quantity (integer). I have worked on this project for probably 15+ hours and have tried so many things and feel like I've barley made any progress...
The part i am really struggling with is taking the data from the text file and creating an object array with it using the product class. Once ive accomplished that, i have to use that data to create a random access file with the data.
Here is the base Product class that must be used to create the objects for the array.
public class Product { public String pName; public String stringName; public double price; public int quanity;
[Code] .....
And then here is the data from the text file that i must extract to use to create product objects.
These continue for about 40-50 entries, they are not separated by a blank line though i had to add those so it would display correctly, each entry is on its own line with name separated with spaces, then price after a comma, then quantity after the second comma.....
New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows
(1) The original list of N numbers from the input file, (2) The original list of N numbers printed in reverse order of how they appear in the input file. (3) The sum and average of these numbers, (4) The minimum of all the numbers, (5) The maximum of all the numbers.
