Read CSV File From Disk And Manipulate Data Inside

Nov 17, 2014

I need to read a csv file from the disk and manipulate the data inside. My problem is that if the csv (excel format) contains "" in any of it's values the whole string line gets saved/displayed incorrectly . For example for the line in the csv file :

1,393275,57319 57321 57323 57325 57327,5_5,200000,393277,57329 57331 57333 57335 57337,3_3,200000,400000,"gi,gi",,,,,,BASS/2.4,,1

it gets read in java as :

"1,393275,57319 57321 57323 57325 57327,5_5,200000,393277,57329 57331 57333 57335 57337,3_3,200000,400000,""gi,gi"",,,,,,BASS/2.4,,1";;;;

instead as :

1,393275,57319 57321 57323 57325 57327,5_5,200000,393277,57329 57331 57333 57335 57337,3_3,200000,400000,"gi,gi",,,,,,BASS/2.4,,1

My code is :

String csvFile = "resources/testcsxs.csv" ;
String l = "";
try {
BufferedReader cz = new BufferedReader(new FileReader(csvFile));
while ((l = cz.readLine()) != null ){
System.out.println(l);
}

What am i doing wrong , how can i read a csv file (excel saved) without getting "" added incorrectly ?

Read Text File Into Array Ask User To Save File And Print Data

Jul 14, 2014

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.

[import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;

How To Read In A File And Extract Data

Nov 15, 2014

I am supposed to read in a file and extract the data. I am trying to add a Long into an Array that I initialized. So this is how my method looks like :

Java Code:

public void readOSMWay(File osm){
try {
Scanner output = new Scanner(osm);
while(output.hasNext()){
String line = output.nextLine().replace("^s+","");
if(line.startsWith(" <way")){
Road way = new Road(line,true);

Use Data Read From File To Create Instances?

Sep 10, 2014

"Write a program (save the program as ProductInventory.java) that will read data about 5 products from a text file (Products.txt. The program should use the data read from the file to create instances (objects) of Product.java(Use Product class as a Reference Type)."

I'm yet to discover how I will get the info from the textfile using scanners but I don't know how to "create instances of a reference type".

This is the code of Product.java that came with the exercise.

public class Product {
private String productCode = "";
private String productName = "";
private int quantity;
private String supplierName = "";
private String supplierAddress = "";
private double price;

[Code] .....

By the way, the exercise also required me to use the abstract class ProductLister. To be clearer, the text file is kinda like this:

54643
Rizer Mouse
Mark5s Merchandising
Marquee Mall

205.50
23412

I am developing a java code using netbeans for encryption decryption by RSA algorithm. Swings and file handling play a major role in these code. My encryption code is working nicely but the code for decryption is not since keys file is not being read. That is why variable mod and pri are getting null values and the following error stack is coming. I know where the problem is somewhere in void readkeys() function but cannot solve it.

Best Way To Read Data From CSV File Then Compare And Display

Jun 13, 2014

I have 3 csv files as follows -

author file columns - emailID | firstname | lastname
books file columns - title | isbn | author_email | description
magazine file Columns - title | isbn | author_email | releasedate

I need to display -

1) Based on the ISBN display all books and magazines
2) All books and magazines by an author
3) All books and magazines by title

I am using Buffered reader as of now -

String csvFileToRead = "csvFiles/authors.csv";
BufferedReader br = null;
String line = "";
String splitBy = ";";

[Code] ....

I am confused about how to proceed with multiple files. Here are the approaches that i have considered -

1) change string csv csvFileToRead to a string array -

String[] csvFileToRead = {"data/autoren.csv", "data/buecher.csv", "data/zeitschriften.csv"};

Pass each index each time to a method returning all rows but getting stuck with DS to use. I think ArrayList wont suffice since i need separated data. Should i use a 2D array? Do i need to read and store data in a DS in order to achieve the goal?

2) Should i make 3 different classes with getters and setters for authors, book and magazine?

How To Read Data From Text File And Place Into Array

Nov 15, 2014

I'm trying to figure out the necessary code for reading integers from a text file, then placing them withing the two-dimensional array I have created, and then finally printing the array using a nested for-loop. I have attached the file I would like to read from. I'm having trouble figuring out how to reference the text file with the integers, and also how to properly create a dynamic preface for each row of the array. I want the preface to display as "Week #: ", with # being the row number. I tried to create an integer to be used that way, but NetBeans tells me whatever integer I declare has already been defined in method main. I know I need to use scanner to read the file. I would like the output to display like this:

Quote
Temperature Data

Week 1: 73 71 68 69 75 77 78
Week 2: 76 73 72 72 75 79 76
Week 3: 79 82 84 84 81 78 78

Using JAVA Scanner Class - Manipulate And Generate Data Dictionary Add Cards For Each

Feb 24, 2015

I have a string of variable tags (tag) filled with variables, and using a Scanner (scan) to manipulate and generate data dictionary add cards for each. The variables are delimited with new line character, and the variables are structured such that the actual name of the variable contains info as to its data type, size, etc. What I need to do is move the scanner to a particular point into the string then use .nextInt() or similar. I don't want to do this to the whole variable, just where I start it from. How can I do this?

E.g..

/* variables in String tag...
ANS_s20Tx12VDstr
ANS_:Tx67MSvis
ANS_zRx11MSctr
...
..
*/

Scanner scan = new Scanner( tag );
int ptr = tag.indexOf( "_" );
ptr++;
if ( Character.toLowerCase( tag.charAt( ptr ) ) == 's' )
// then start at the "_" character and grab the nextInt()

I/O / Streams :: Reading From And Writing To A File Then Read Again Including Data Written

Oct 11, 2014

I'm having a bit of trouble with using the Scanner and the Printwriter. I start with a file like this (1 = amount of Houses in the file)

1
FOR SALE:
Emmalaan 23
3051JC Rotterdam
7 rooms
buyprice 300000
energylevel C

The user gets (let's say for simplicity) 3 options:

1. Add a House to the file,
2. Get all Houses which fullfil requirements (price, FOR SALE / SOLD etc.) and
3. Close the application.

This is how I start:

Scanner sc = new Scanner (System.in);
while (!endLoop) {
System.out.println("Make a choice);
System.out.println("1) Add House");
System.out.println("2) Show Houses");
System.out.println("3) Exit");
int choice = sc.nextInt();

Then I have a switch for all of the three cases. I keep the scanner open, so Java can get the user input (house = for sale or sold, price = ... etc). If the user chose option 1, and all information needed is inputted and scanned, the House will be written to the file (which looks like what I typed above).

For this, I use try (PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter("Makelaar.txt", false)))). This works perfectly (at least so it seems.)

If the user chose option 1, and all requirements are inputted and scanned, the Houses will be read (scanner) from the file and outputted. For this I use the same Scanner sc. This also works perfectly (so it seems atleast).

My problem is as follows: If a House has been added, I can only read the House(s) which were already in the file. Let's say I have added 2 houses, and there were from the start 3 houses. If option 2 is chosen, the first 3 houses will be scanned perfectly. An exception will be caught for the remaining 2 (just added) Houses. How can I solve this? I tried to close the Scanner, and reopening it, but apparently Java doesn't agree with this

Aug 7, 2014

i am fairly new to java but have made a few projects so i do know most aspects that would allow me to complete the task its just i have been stuck at the same place now for 2 days.The project is to create a java program that can read specific data within a csv file to work out the averages etc. The csv file is a database of different weather stats . an example of the first 12 months of the csv file is below..

[CSV FILE]

year ,month,average rainfall etc

1946 15.70.616108.131.5
1946 28.23.56111.871
1946 38.82932.9 102.9
1946 414.16.3029.2 150.5
1946 513.96060.7 143.6

[code]...

I know that once the data is indexed i can than use a double to find the average of the 12 specific pieces of data and so on. once this is complete i should than be able to transfer the data to a simple graph.

Read Date From File / Calculate And Then Displays That Data In Table Format On Screen

Apr 22, 2015

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.

import java.io.*;
import java.util.Scanner;
import java.text.DecimalFormat;

How To Get Data Inside Table Row When That Row Is Clicked

Dec 19, 2014

I am using netbeans swing to do my little project . I have one table which is populated by data from a database. I also have another table which should be populated when a user selects a certain row in the first table.Both table have only one column. The logic is when a user selects on row 1,the data in that row should be obtained and should be used to search for certain entities in the database which are returned and used to populate table 2.So after a user selects row1 and decides to select row2 the second table should be updated accordingly. I have attached the java file

Swing/AWT/SWT :: Window To Submit Data Freezing When Created Inside Mouse Clicked Event

Feb 18, 2014

I'm trying to right a GUI in swing, and as part of my program, I want to open a secondary window out of the main window when a mouse clicks on the main window. Then, once I click a button on the secondary window, I want that window to close and submit data to the main window (like an info form). I have almost figured out how to do this, except for one problem. By putting a variable inside my form window called "ready," and then in my main window running a loop that constantly checks if ready is true and doesn't proceed until its true, I can create the form window, modify the values in it (currently just one value called "difficulty" that's modified by a jSlider), and then when i click the "begin" button, ready is changed to true, the form window closes, and the main window can proceed. However, when I try to put the while loop checking the ready variable inside a mouseClicked method in the main window, the form window freezes when it opens, and you can't see any of its content or modify it in any way (you can't even close it).

Here is my code:

//form window class
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class formWindow extends JFrame {
private JTextField instructions1;
