GUI Button Write To File

Dec 8, 2014

I have created a program that allows a pizza shop to enter a customers orders (via 3 seperate panels of options), and calculate a total. Everything works just fine, and now we have to take it a step further and record the sale data in a .txt file (which will include the Crust Type, Toppings, and Extras).

I need to make it so that when a user clicks the calculate button, it also writes to a file (in this case, SalesRecords.txt). I have it all set up, but for some reason I can not get it to work. The error I get is:

"error: unreported exception FileNotFoundException; must be caught or declared to be thrown
PrintWriter outputFile = new PrintWriter(filename);

Here's my code: (the calculate button that I am working with is indicated by a comment)

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.text.DecimalFormat;
import java.io.*;
import java.io.BufferedWriter;

[I looked up the exception I got, and just so everyone knows I made sure that the file "SalesRecords.txt" DOES EXIST. It is in the same folder as my java and class files for this program. I even tried defining the absolute file path for SalesRecords.txt and that changed nothing.

Using Serializable To Write Everything To A File At Once?

Nov 3, 2014

For a class, I'm making a prison system program. The prison has cell blocks, each cell block has cells, each cell has bed(s), and each bed has prisoners. There are also visitors and visits. I thought, rather than write all of those to different files, I could just write the entire prison to a file and make all the classes under it implement serializable. The instructor said that is a bad practice and we shouldn't do it. So I'm thinking I'll make the prison non-serializable. But the prison has maps of cell blocks, inmates, visitors, and visits. I think I'll make all those serializable and I'll also make everything a cell block contains serializable as well. Then I can just read the cellblocks from the file. But is that too easy as well? Is that a bad practice?

Write TextArea To File Formatting?

Dec 10, 2014

I want to write a text area to a file which I have accomplished however the formatting for how it is written into the text file is different. Is there a different library I must use to retain the formatting?

I'm using a BufferedWriter to write to the file

if (!file.exists()) {
try {
BufferedWriter output = new BufferedWriter(
new FileWriter(file));
output.write(textArea.getText());
output.close();
} catch (IOExcception io) {
io.printStackTrace();
}
}

If I write this into the text area:

DreamInCode
YouTube
Google

The text file contains text that says:

How To Write ItemsInCart List To A File

May 14, 2014

Main:

package shoppingcartselection;
import javax.swing.*;
import java.util.ArrayList;
public class Main

public static void main(String[] args)
{
ArrayList<Item> items = new ArrayList<>();

[Code] .....

I have it to save to a text file the subtotal, sales tax, and the total cost of all items in the cart after clicking on Checkout. I need it to also show the Items that where in the cart, along with how much each Item costs. I've tried this:

public void save(ArrayList Receipt) throws FileNotFoundException
{
PrintWriter pw = new PrintWriter(new FileOutputStream("Receipt.txt"));
for (Item itemsInCartNames : itemsInCart)
pw.println(itemsInCartNames);
pw.close();
}

But this is what gets saved to the Receipt.txt file:

shoppingcartselection.Item@16752c9

itemPices.txt:

GUI Program - Read And Write To File

Oct 17, 2014

I'm rather new to programming and I'm trying to make a gui program that will allow the user to create text files. They will be prompted to enter what they'd like to save their file as and then they will be allowed to input text to that file . They will also be allowed to open their files to modify or view its contents. So to start things off, I'm making a prototype if you will.. I've been able to save to a file the problem occurs when I try to read/display it.

Main Class:

public class MainActivity {
public static void main(String[] args) {
// Access to other classes
WriteFile writer = new WriteFile();
ReadFile reader = new ReadFile();

Null Pointer Exception When Trying To Write To File

Aug 14, 2014

I've been closely following a tutorial series, and as far as I can tell my code is exactly the same, but not functioning.

The app throws a nullpointer exception here on "controller.saveToFile(fileChooser.getSelectedFile ());"

// Export data item
exportDataItem.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (fileChooser.showSaveDialog(MainFrame.this) == JFileChooser.APPROVE_OPTION) {
try {
controller.saveToFile(fileChooser.getSelectedFile());

[Code] ....

There are no errors popping up in the code, and I dont understand why there is a null pointer exception when Im saving this file.

Write And Read Via ArrayList With Text File?

Feb 6, 2015

I wanna learn to create a method where I use a scanner or any other way to input.The stuffs I input will be strings. The whole thing will be like a destination creator.So if I input the string USA, it will write this to a file:

1:USA

When I go to the method again the ID will be added so if I input UK, the file will contain:

1:USA
2:UK

Now if I terminate the program, next time when I run it again it will be able to read the ArrayList, so if I wanna go to the method again and write: Norway the file will contain:

1:USA
2:UK
3:Norway

Later I also want to be able to use println to show all of these lines from the file, as well I would like to be able to delete an ID, so if I delete ID 2 the file would contain:

1:USA
3:Norway

I'm quite new to Java, I'm in a Java course since soon 3 weeks back and I have sure learned a lot, all the loops and basic statements that exist in most languages, but now when it comes to this I just don't understand.

Read Three Files Using MultiThreading And Write Into A New File

Apr 21, 2014

I got a question in my last interview, its all about multithreading, interviewer asked me to write a program, to write the contents of three files(F1,F2,F3) in to a new File F4, using multithreading , first thread should read the first file and second thread should read second file, so the File F4 should contain F1's contents in first then F2's contents after that etc. I tried to give my best shot, but i couldn't get a way to ensure that the first thread is reading the first file and write to F4 then second thread reading the second file and writing once first file is written completely into F4 and so on ..how to do this?

Write Same Data To Stdout And To Save File

Apr 11, 2014

I need to write the same data to stdout and to a save file. In C I'd do something like:

void doWrite(int fd, char *stuff) {
fprintf(fd, stuff);
}
if(someFlag)
doWrite(STDOUT, data[]);
doWrite(saveFd, data[]);

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.

Write User Input To Text File

Dec 8, 2014

I need to write a program where the user inputs name, age, email, and cell and write the user inputs to a text file. I need to have it so the file can be added to if more than one set of information is added. Currently, every time I click the button, the file is overwritten instead of added to. How do I correct this? Current code is as follows:

try
{
FileWriter writer = new FileWriter("ContactInformation.txt");
BufferedWriter bw = new BufferedWriter(writer);
nameTextField.write(bw);
bw.newLine();
ageTextField.write(bw);
bw.newLine();
emailTextField.write(bw);
bw.newLine();
cellTextField.write(bw);
bw.newLine();
bw.close();
nameTextField.setText("");
ageTextField.setText("");
emailTextField.setText("");
cellTextField.setText("");
nameTextField.requestFocus();
}

How To Write Exact Directory Path To Properties File

Nov 27, 2014

I need to write the exact directory path like C:LisaestUpdate to a properties file.

I am trying it by

FileInputStream in = new FileInputStream(test.properties);
Properties props = new Properties();
props.load(in);
in.close();
 FileOutputStream out = new FileOutputStream(newprop.properties);
props.setProperty("myDirectory","C:Lisa estUpdate" );
props.store(out, null);
out.close();

but the properties file is updated as C:Lisa estUpdate

Extra comes before :.

How can I remove that.

Even I tried it with an command but got same output.
