Split Text File In Multiple Files
Jun 17, 2014
I have multiple text files that contain several docs. my files look like this:
<doc id 1> some text </doc>
<doc id 2> some more text</doc>
...
As output I want to extract the text between the tags and then write the text into several files like 1.txt, 2.txt ......
here is my code so far:
import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Scanner;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
[Code] ....
I can not seem to get around how to print the text into several files.

I am trying to split the contents of the text file and assign the value on the left of the separator to a variable and the value on the right of the | separator to another variable. Thus I tried out a sample code to print all the values in the split [] first, and ended up with problems. This is the content of the text file:
Crazed Boy|20
Hello|5
MSB|6.5
public class Main {
public static void main(String[] args) {
try {
BufferedReader infile = new BufferedReader(new FileReader("test1.txt"));
for (int i =0; i < 3 ;i++) {
String s = infile.readLine();
String[] ss = s.split("|");
[code]....
I keep getting IOException in my sample code, why is this so ? I assumed the split() method is supposed to output for the 1st iteration:
ss[0] = Crazed Boy
ss[1] = 20

I am trying to read a text file into Java and split the text into tokens. Eventually I want to be able to count the number of instances of a specific word. However, at this point, when I run the file, all I get is the location of the file rather than the text in the file.
import java.util.*;
import java.io.*;
public class textTest3 {
/**
* Prints the number of words in a given file
*
* @param args
* @throws IOException
*/
[Code]...

For example, if I had a text file with one line such as "first, second, third", would there be a way to make it so I could make "first" go to the first array list, "second" to the second, and "third" to the third?
I haven't posted any of my code so far as it wouldn't be right to be handed the finished code on a platter and I should put the work into it, but I'd just need a loop to make it go through the rest of the lines in the text file to add all the first, second and third parts of each line, right?
(I already know how to input data from a file, but not how to split up a line into bits to put into different array lists).

So I have a text file, and I want my Java program to store names from the text file. How do I do that? This is what I have so far.
Java Code: import java.util.Scanner;
import java.io.File;
BingoCard[] cards = new BingoCard[n]; //Array of BingoCard objects, n being the length of the Array
Scanner sc = new Scanner(File("Names")); //Names is the name of the file
for(int c = 0; c < cards.length; c++)
cards[c] = new BingoCard(sc.nextLine); mh_sh_highlight_all('java');
Here's the constructor.
Java Code: private string myName;
public BingoCard(String name)
{
myName = name;
} mh_sh_highlight_all('java');
Whenever I compile, I get this error message.

</T0020>
so i have applied following xslt ...
<?xml version="1.0" encoding="UTF-8" ?>

[Code] ....
Now I want to apply this XSL to xml through Java Code...
TransformerFactory tFactory = TransformerFactory.newInstance();
Source xslSource = new StreamSource(xslFilePath);
Transformer trans = tFactory.newTransformer(xslSource);
trans.transform(new StreamSource(xmlFileName), new StreamResult( ????));
Here how can I map new StreamResult( ) input parameter with xsl Result document argument ??
Or Can you give me a link of Example which use result document and Java transform method to Output multiple document ??
Here new StreamResult take only 1 file as to be transformed ....

I have to read a text looking for value related to certain variable. The variable are always DE plus identifier from 1 to 99 or DE plus identifier from 1 to 99 and SF plus identifier from 1 to 99. The value can be alphanumeric. How can I get these values? As a start point, I try to use split("DE") but I can get something that is wrong if there is "DE" inside the text that doesn't me interest. I look for scanner but it doesn't work. I guess that there is some way, maybe using regex but I am completely lost ( I have never used regedix before and I am in rush to fix this).
Basically, the text is similar to the below where DE means data element and sf sub field. Some data elements have sub fields while others don't. I guess that there is a way to split with something like DE+anyNumberFrom1To99 = theValueAimed in some array and DE+anyNumberFrom1To99+,+SF+anyNumberFrom1To99 = theValueAimed in other array.
DE 2, SF 1 = 00 SOME TEXT THAT DOESN'T INTEREST ME
DE 22, SF 1 = 0 SOME TEXT THAT DOESN'T INTEREST ME
DE 22, SF 4 = 1 SOME TEXT THAT DOESN'T INTEREST ME
DE 22, SF 5 = 0 SOME TEXT THAT DOESN'T INTEREST ME
DE 22, SF 6 = 11 SOME TEXT THAT DOESN'T INTEREST ME
DE 22, SF 7 = 90x SOME TEXT THAT DOESN'T INTEREST ME
DE 22, SF 7 = 12ab SOME TEXT THAT DOESN'T INTEREST ME
DE 99 = 1234 SOME TEXT THAT DOESN'T INTEREST ME

[Code].....
This is actually my question:
Java Code:
1. billing-20140527[09].txt has
a)XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
b)XGMS,2034-05-27 30:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
2. billing-20140527[10].txt has
a)XCGS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
b)HELO
[B]I try to find the number 1 in both text files, if lets say I input the text file name is billing, I can find the number 1 in both text file and output them:[/B]
a) XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
b) XCGS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040.
[B]However, if I specify the text file name: billing-20140527[09].txt and find the number 1 inside the text file, it will only output:[/B]
a) XGMS,2014-05-27 10:08:04,122,PLAYER_VERIFY,VERIFY to LBA,0x580000,0xC0000,253040. mh_sh_highlight_all('java');
So far, I can't get this program to run,

I need to download multiple files from my jsp,My jsp will receive a string array,and in that each array will have a filePath.I ggot the solution to download multiple files by Using ZipOutPutStream,But i don't want to Zip Them,I need to download them in a folder.In that folder i should have all the files.
<c:set var="streamValue" value="${streamValue}"/>
<%!
void addFile( ZipOutputStream outZip, File f, String name ) {
FileInputStream in = null ;
try {
// Add ZIP entry to output stream.
outZip.putNextEntry( new ZipEntry( name ) ) ;

The problem is what to do when the source file for a class gets too big ( a judgment call for sure). Is it possible for one class to be defined in multiple files and if so how do you do it, and is it good practice?
I do see ways to refactor into a base class or move code into a helper class but sometimes the abstraction is cleaner as a single class that does a lot of stuff. My problem is how to organize a BIG class?

I'm going through a file (MySQL dump) and I wish to take the SQL and create individual files for each table (as opposed to what I do now, which is just run through the whole thing).
<code>
BufferedReader myDumpfileReader = new BufferedReader(new FileReader(tfDumpfile.getText())); BufferedWriter myDumpfileWriter = new BufferedWriter(new FileWriter("/users/linehanp/mydb/bin/tgac_dump/Vanilla.sql"));
while((dumpFileLine = myDumpfileReader.readLine()) != null){ DoStuff();
MyDumfileWriter.write("Whatever");
}
myDumpfileReader.close();myDumpfileWriter.close();
</code>
Now, this all works fine - but what I want to do is create a separate .sql file for each table.
However, I can't figure out the best way to do this - how do I create a new FileWriter (or instance of whatever class is required) as I'm going through the while loop? That or pointing the same one to different files as I go through the loop.
It can be assumed that the file may exceed RAM - I want to do it line by line rather than slurping the entire file as a string and "cheating" that way.
There appear to be many (a bewildering amount of) I/O options and I'm just unsure.

I have a multi scene JavaFX FXML application [URL] ....
I have added a TextField to Scene2.fxml and Scene3.fxml files each scene has its own Controller Class with a ScreensController class that loads a HashMap with Id name, Node screen that is defined in the ScreensFramework
class (Main class)
public void addScreen(String name, Node screen) {screens.put(name, screen);}
So each time you click a Button on a screen (scene) you fire an ActionEvent and move to another screen
myController.setScreen(ScreensFramework.screen2ID);
What I would like to do if it is possible is use the value in the TextField on Sceen2 and transfer it to the TextField on Scene3. I have discovered that unless both FXML files are loaded this is so far not possible. This is a desktop application. So how do you create a variable that is GLOBAL and has a life after one class is unloaded or one FXML file is unloaded?
At this point I do not want a database to accomplish this task.I have developed in Visual Basic 6 where I would just declare a global variable that could be used through out the application.

I am trying to compile multiple jar files into one jar file from inside a java program. I know how to do this with shell scripts but I would rather have a universal application than one that will only run on Mac, Windows, or Linux. This is my current compiler code:
if(System.getProperty() == "Mac OS X"){
Runtime.getRuntime().exec("javac -classpath jar1.jar; jar2.jar");
}
I would then continue this on for Linux and Windows, but this limits my application.

Lets say I have a desire to convert and entered value to Centigrade or Fahrenheit and that I have two Radio Buttons to designate the type of conversion with the Answer posted to a TextField on Scene Two from a button click event on Scene One ok Now I would like to convert the value in the TextField on Scene Two to Kelvin and reflect the value on Scene Three in a TextField by clicking a button on Scene Two
lets say I have 4 FXML files sceneONE sceneTWO and scenMain and I created 4 controllers ControllerONE and MasterController
So far I can navigate to the different scens with just the MasterController code below...
BUT because I have two FXML files I can not capture the value in the first FXML file and pass it to the second scene
This project is my attempt to adapt the FXML style code from this web site
Switching to Different Screens in JavaFX and FXML | JavaFXTutorials
Which uses this code to switch scenes
//get reference to the button's stage stage=(Stage) btnS1.getScene().getWindow();
//load up OTHER FXML document
root = FXMLLoader.load(getClass().getResource("ATTwo.fxml"));
But will not permit variable transfer due to scope of variables which reside in two different FXML files
public class MasterController implements Initializable{@FXML public Button btnS1;
@FXML public Button btnS2;
@FXML public Label lblS1;
@FXML public Label lblS2;
@FXML public TextField txfS1;
@FXML public TextField txfS2;
@FXML public AnchorPane root;

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 managed to retrieve data, and set data in my own ways in which I like. But my problem is, if the file does not contain anything (fully empty), when I try to use my
set("", "");
method, it only sets the last one that is called.
Example:
set("section1", "section1Item");
set("section2", "section2Item");
set("section3", "section3Item");
Only section3 would get set, and not the others.
Otherwise, if the file contained a section already, then each section (section1, section2, section3) would get set.
Here's how I set the data to the file:
public static void set(String section, String data) {
files.openFileWriter();
files.file.delete();
reCreateFile();
String beforeItem = section + ":" + files.dataList.get(section);
[code]....
And here is how a retrieve the data and set them to my arraylist/hashmap:
public void getData() {
String line = null;
openFileReader();
StringBuffer sb = new StringBuffer();
[code]....
