Read All XML Files From Parent Folder And Write In Spreadsheet
Apr 21, 2015
I have a requirement to read all the xml files from a parent folder and write in a spreadsheet(separate spreadsheet for each xml file)
I have written the below code in which xml and excel file name are hardcoded. The format of xml file is same.
package xmlexcel;
import org.apache.poi.hssf.usermodel.*;
import java.util.ArrayList;
import java.awt.List;
import java.io.*;
import java.util.ArrayList;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.xml.sax.SAXException;
[Code]...

I have seen different methods of creating and reading files (specifically text files) in Java. The PrintWriter method or the Formatter with a Scanner to read the file, using a BufferedWriter with a BufferedReader, etc. They will all read/write text files, but from what I understand they do so in different ways. When would it be more beneficial to use a buffered writer than, say, PrintWriter, which is much simpler code-wise? Is there a "best" way to handle i/o in general in Java?

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?

I have an excel spreadsheet, with a specific filename and location which doesn't change (e.g. C:/workbook.xls)What I would like to do is have a window open when I open an .exe file, and in this window is a bunch of check boxes, text areas and drop down boxes (I can implement these, that's about my level of JAVA)
Then, when I click on a button in this window (for example, a button which says "Save"), the data from all these boxes and menus etc. goes into specific cells in the excel spreadsheet. Or if certain values are selected from a drop down menu, then a bunch of cells are empty.

i have to save some particular info of a pdf file info into a database.there are lots of folders with tons of pdf files to be analized and then getting that info saved. make the process incremental? i need the program to stop at some point. and then continue to analize the resting files in the folders (i dont want the program to start all over again from 0 )my ideas are..sorting all the files using apache commons sort (by date) method (iv seen it somewhere) and saving the last file analized in the dabatase to then continue. OR just adding some extra character to the pdf file name that has been analized like for example xx-xxx.pdf to xx-xxxa.pdf.

-I created the project with the checkbox "Create separate folder for sources and class files."
-I've tried running the program with the "mfq.txt" file in the root directory, the src directory, and the bin directory.
-I've even tried it in all three directories at once!
-I've also refreshed my project after each change in eclipse
-My error is the "FileNotFoundException" error
Here is the line giving me trouble
Scanner file = new Scanner(new File("mfq.txt") );
Where my code is wrong/where I should put my file? :tax:

I am currently using the following Rally API Java code(below...in Java 1.7) to create an object and attach a file to it. This code works fine. But I need the code to be a little less specific and attach all files located under a folder (not just one file). How could one potentially rewrite this code (or use a different constructor/method) to accommodate such a thing? Also additional code how to narrow down results to all files with a creation date >= today.
Java Code:
import com.google.gson.JsonArray;
import com.google.gson.JsonElement;
import com.google.gson.JsonObject;
import com.rallydev.rest.RallyRestApi;
import com.rallydev.rest.request.CreateRequest;
import com.rallydev.rest.request.DeleteRequest;
import com.rallydev.rest.request.GetRequest;

Where can I learn or how can I, being the most efficient way known to do so, create a folder outside my JAR file with the java source code, this then will copy YAML documents from my JAR file to that folder, then I need to read the YAML documents some way. I'm making an addon for a game, I am using an API that allows you to make a config.yml easily, and add and read entries from it, but I've read that I need to make my own methods to be able to create additional YAML documents.
I don't exactly know what to type in google to perhaps find such a page, but I did try to find a tutorial page about this or something and couldn't.
I've partially figured out how to create a folder, but I have a problem, how can I RETURN one directory to make the folder, I don't want to make the folder in the JAR file I want to make it just outside the Jar file in the same folder that the Jar file is at.

I'm trying to write information into a file using PrintWriter. The program complies correctly but when it get's to the following part of the program, an error is given. "Exception in thread 'main' java.io.FileNotFoundException" What is wrong with it?
System.out.print("Enter the filename:");
filename = kb.nextLine();
PrintWriter outputFile = new PrintWriter(filename);
outputFile.println(balance);
outputFile.print(item1+" "+item1Price);
outputFile.println(" "+item1Quantity);
outputFile.print(item2+" "+item2Price);
outputFile.println(" "+item2Quantity);
outputFile.print(item3+" "+item3Price);

I'm refitting a snippet of code I found on the net to write stuff into text files. After a bit of fiddling, here's what the code looks like in one of my classes:
public void addItem(String Item){
try{
Writer out = new OutputStreamWriter(fos, "UTF8");
out.append(Item);
out.flush();
// out.close();
}
catch (IOException e) {
System.out.println(e.toString());
}
}
The original snippet included the close() method. However, when I tried to do a test run writing multiple lines, I'd get an IOException about the stream being closed. I removed the close() method line, everything seems to work the way I want it, but I just wanna know if there's anything I'm missing out on by not having the close() method anywhere, especially when the IDE finds it important enough that it lit a warning about the stream not being closed somewhere as I was repurposing the original snippet.
