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 need to read folder structure from the excle file and need to read all the files which are available inside folder structure.folder structure like below

I am trying to write a program that read from a csv file called matches.csv.
A single football match can end with a win or a draw: in first case the winner team get 3 points and the loser none, in the second case of draw each of the two teams get 1 point.
For example, the first line of the file matches.txt is as follow:
This means that a match has been played on the 17/08/2013 where Arsenal scored 1 goal while Aston Villa 3 goals: thus Arsenal got 0 points while Aston Villa 3 points.
How can I structure my output to make it make it read
Position Team Played Points 1 Aston Villa 2 3 2 Liverpool 1 3 3 Arsenal 1 0
import java.io.File;
import java.io.FileNotFoundException; import java.util.Scanner; public class Teams { public static void main(String[] args) { String fileName = "matches.csv"; File file = new File(fileName);

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 am quite new to Java. I have downloaded a tictac example Java applet code and I run it on Eclipse with no problems. But when I try to test it outside Eclipse by doing the following:
I copy the .class file and two gif-images to another location and call the Java from html code:
If I draw (drawLine) the X and O instead of using gif, then it works.... so its really the gif-loading which is the problem.
I have a Windows XP. I also tried to run it inside XAMPP server folder in my machine but the same problem. How could I be able to run it on my machine?
I have a program that is a XML-parser, and it works fine when I'm running it from NetBeans. But when I create a JAR-file and run the very same program, it cannot find the xml file. Consider this small program that addresses my problem:
I am trying to make a Library that will read some Input Files from a File . Like When We Enter Nuber from a System.in
1 2 45 667
77 34
and then store these values in int[] array
What I want is I Save all these values in a File and at Run time pass path of that file to command line arguments and then int[] array will be initialize using that
In a program I created, I'm using a text file that contains some texts needed for the program. The method relevant to this is something like the following.
private String wordgen(){ try { BufferedReader reader = new BufferedReader(new FileReader("src/Resources/adjectives.txt")); Random rand = new Random(); int low = rand.nextInt(400); String fil=""; int i=0; while(i!=low){
[Code]...
The program runs fine in netbeans project but once the jar is created it does not corporate with the text file. ("null" is returned) How can I attach text files to jar and exe?
I need to transformation the txt files into xml files, but each row txt files don't have same elements, for example the first book is composite one author
One of my official site is not disaplying the content in machine#1 IE10 browser.And the same site is showing data in another machine#2. I compared the both machines JRE and JDK settings but no difference found.
I'm a first timer at jsf, and right now I'm learning how to use ajax in jsf. i got a problem when i click a command link i want to change in a content, but when i run my web and i click the command link it didn't do anything. This is the source :
<?xml version="1.0" encoding="UTF-8"?> <!-- To change this license header, choose License Headers in Project Properties. To change this template file, choose Tools | Templates and open the template in the editor. --> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"
[Code] ....
In this code when i click the Home button it suppose to change the ouput text to a string that store in my bean. This is my bean:
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package UI; import javax.faces.bean.ManagedBean; import javax.faces.bean.RequestScoped;
[Code] .....
At first the output text value is the same as the string i store in the bean. but when i click the commandlink, it didn't do anything, is there something wrong with my code?
I am trying to read a content of file downloaded from ftp and return it as a String. This is what I use:
Java Code:
import java.io.BufferedInputStream; import java.io.IOException; import java.io.InputStream; import org.apache.commons.net.ftp.FTPClient; public class Test { public static void main(String [] args) throws IOException{ FTPClient ftp = new FTPClient();
[code]....
The code does not work, although all the links are correct.
String contentType = fi.getContentType(); gives text/plain when my file is.txt file and gives image/jpeg when my file is .jpeg file but when my file is .jar or .docx it will return application/octet-stream and application/vnd.openxmlformats-officedocument.wordprocessingml.document respictively so what to do to get exact mime type.
