I want it to save the names of the "Items" that were put into the "Cart" along with their retail prices and the subtotal of all of them, and the sales tax, and the final total, to a text file.
Main:
package shoppingcartselection;
import javax.swing.*;
import java.util.ArrayList;
public class Main
{
public static void main(String[] args)
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.
This part of the code searches for every word in the text file and saves it to an ArrayList. It searches for the word if its valid of not.How can I offer a list of similar words when the word that the user inputs is not in the dictionary. Also I want it to prompt the user to accept the word or enter a replacement that gets saved in the dictionary.
I am writing to a file coordinates of texts using PathIterator (Java Platform SE 7 ) saved as SVG format i defined the Font attributes using AttributedString (Java Platform SE 7 ) and TextLayout (Java Platform SE 8 ). It is saving to the file and working properly, but it is just writing as a single line of text where is my target is multiple lines of text, i began using LineBreakMeasurer (Java Platform SE 7 ) Class, but some text is removed plus i got single line of text only, where i face the problem that , How to determine the width to get multiple lines of text ? i tried to figure out from this exampleDrawing Multiple Lines of Text (The Java - Tutorials > 2D Graphics > Working with Text APIs) where is drawing multiple lines of text but i am using getBounds().getWidth() of TextLayout object the code i tried
i can't make the [JfileChooser] save text file instead of opening files.that [ComboBox] always don't show me the items that i have inserted in eclipse.
How to force browser to open/save/save as the file from server instead of browser cache.
I am creating a csv file through a pl/sql procedure and forwarding the link to user once user clicks on link he downloads the file, however if the same thing is repeated then browser returns the old cached file instead of new file generated on server.
I am currently working on a project that can save text from a JTextArea and also open that same saved text. The problem I am having is that when I open the saved text file it is no longer formatted.
How the file looks before saving/closing:
public class HelloWorld{ System.out.println("Hello World!"); }
How the file looks after being saved/closed then opened:
public class HelloWorld{ System.out.println("Hello World!");}
When I save the file I'm actually saving the entire thing to a single string. When I do this the String eliminates all tabbed spacing and pushes all characters to one single line.
The only ideas I had for fixing this were to either somehow use Format in the String class or record every time user tabs and add to the String.
is my current exercise.so far i have gotten the code to create a file, and ask the user to input their age.what should i use to save what the user writes into the file?
Java Code:
package assignment7; import java.io.*; import java.util.*; public class Exercise2 { public static void main ( String [ ] args ) throws IOException { Scanner scan = new Scanner(System.in);
Here my code . Iam trying to open text file in window_pane it will open when i click on save it will ask destination to save file if i save example like Read.txt it will save...when i go and check in that folder Read.txt file won't found...what is the error ....
Java Code:
import javax.swing.*; import javax.swing.filechooser.FileFilter; import javax.swing.filechooser.FileNameExtensionFilter; import java.io.*; import java.net.MalformedURLException; import java.awt.*; import java.awt.event.*; public class Read extends JFrame
Here my code am trying to open text file in window_pane it will open when i click on save it will ask destination to save file if i save example like Read.txt it will save...when i go and check in that folder Read.txt file won't found..
I have a program that reads lines of text, but some of the lines of text aren't applicable and break the program. I'd like to put a letter in front of the lines in the .txt file I want to use, such as a #.
I need to make an if loop that'll check for the first letter on the line being #, and use the line in the program if true and skip if false. I'm guessing a boolean variable would be useful here to be true or false depending on the presence of #, but I don't know how to only read the first letter of each line, how can I do this?
I insert a link to a file, that you need to download. After I click the download button and that's performed this action. And how me save the file, where i chose?
private void actionAdd() { JFrame parentFrame = new JFrame(); JFileChooser fileChooser = new JFileChooser(); fileChooser.setDialogTitle("Specify a file to save"); URL verifiedUrl = verifyUrl(addTextField.getText());
Google shows me how to use file I/O, and how to use stdio, but not how to combine the two easily.
With my *nix command line I could "program file | tee savefile", but savefile holds the result of prior runs, gets read before I parse 'file', and this command line zero's out savefile before the program can read it.
The data is standard ASCII, I doubt I'll ever have 20k of data.
I have the file in my project sitemap.xml, which i am trying to write via XMLStreamWriter. My code gets successfully executed as i can see the logs. But my sitemap.xml file keeps blank. Why nothing is getting write in my sitemap.xml file. Below is my servlet code.
I have wrote this class who read from text line by line and save the words in fileOnTable.. Now i don't know what to read in ReadOffer to save the words in object offers and return this.. One more question.. What JUnit test can write for this code..?
I am wondering how to do the following:when a user clicks on a save menu item, a save JFileChooser pops up. I would like to have a default file name set in the FileName box on the chooser, similar to what applications like Microsft word has. Right now, no file name will appear until the user has selected a file.I also need to know how to get the text from this box in the case that the user enters a new file name (the getSelection function is not useful here because the user will not have selected an existing file.)
7.Front desk search the vacant room to be assigned to the guest
Functions:
1. View all rooms 2. Add Customer to a room 3. Display available room 4. Delete customer from a room 5. Find room from customer name 6. Exit
Files:
One file use to store room info. (to be retrieved by program)
One file use to store rate info. (to be retrieve by program)
One file use to store the booking details (to be created and write by the program).
Currently I have write a program but only compiling and display the output to the console. How to modify my code below to be able to save to the .txt file
Here is the code:
import java.util.*; import java.io.*; class Customer { private String name; private int room; public void setName(String name) { this.name=name;
My assignment is to make GUI to calculate orders and to save the calculation to .csv file.I have solved "save" button and it really does save my input to .csv file.But, my problem is "Load button" When I press it, how to load .csv file to my existing JTextFields?
01. pickup the selected text file and read the line by line and output the text in to visual text pane.
what i did:.
01. I wrote code that read the text file and output in to jave console/ also some of the interface.
the code read txt file:
Java Code:
String fileName = "C:/Users/lakshan/Desktop/lawyer.txt"; File textFile = new File(fileName); Scanner in = new Scanner (textFile); while(in.hasNextLine()){
[code]....
so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?
I have a project to create an application where you can print all the detail to be written on a receipt (no more manual writing). I already have blank receipts. All I want to know is how to do that printing the details at exact position in my blank receipt. I'm starting to read about Jasper Reports but I don't know how it will work since most of its example are creating template.
Okay so my main problem is that i can't seem to initiate three objects in order for it to display like a recipt in a way. Here is the picture of what the out is suppose to look like : Here are all three files of code
public class IceStand { //Defining the properties private String Name; private String location;
[Code] ...
Output looks like currently
Please enter name of Shaved Ice Stand: People who love ice cream Please enter your zip Code: 21236 Enter number of Small (press -1 to stop): 0 Enter numebr of Medium: 1 Enter number of Large: 1 PEOPLE WHO LOVE ICE CREAM 21236
Basically I am trying to make a POS system and need a way to print a receipt whether there are 1 items sold or 50. So I used a Arraylist. This is the format for the printer that is needed:
printer.printNormal(POSPrinterConst.PTR_S_RECEIPT, " 2 200 Tx Hashi Chop Sticks" + LF);
This is what I tried to do:
ArrayList<String> receiptLine = new ArrayList<>(); public void captureSales(){ receiptLine.add("Test"); System.out.println("Size of the receipt list is: "+receiptLine.size()); System.out.println("Element at index 1: " + receiptLine.get(0));
