I am suppose to display some information from some text files I tried to do that but the output gives me information from one text file and not information from all text files.
public static void main(String args[]) throws IOException {
String occupations;
double unemployRate_By_Occupations_2008;
double unemployRate_By_Occupations_2009;
double unemployRate_By_Occupations_2010;
//declare the file object and open the file "occupations.txt";
File myFile = new File("occupations.txt");
[code]....
The first text file is:
2.5
3.3
2.6
3.1
2.4
2.7
2.6

the second text file is:
4.6
5.7
5.2

I have a query regarding parsing a directory, its subdirectories and files of directories. i am using File Object to load absolutepath of main directory and checking file is a directory or file but not geeting exact solution what i want. Suppose directory structure is D:TestPC
PC is a directory and have 2 files test.txt test1.txt and one directory PC1 directory contains 2 directories PC2 ,PC3 and each PC2 and PC3 have some files.
Now my query is : i want to store each directory in HashMap and its files corresponding to its directory. E.g.:
I am trying to merge two files together using the Apache Commons CSV library. I figured it was easier to use this than to write my own implementation.
The first problem is that the output contains the underlying class logic and as a results my output contains a bunch of un-needed data. How do I get rid of this? I just want the column and row data, nothing else.
The second problem is that I just want the row Headers from the first file, but the row headers from my second file are still being included in my output. I used withSkipHeaderRecord(true), but it didn't have the desired results.
I have an xml with 'n' number of data which i am parsing,for test i hardcoded without looping has below,now the below line is just parsing and showing the data for index '1' ,i need to loop this and i am not sure how can i do this.How do i find the length of obj and loop,i cannot find any method in SoapObject.I used like below but the data is getting overridden after parsing
for(int i=0;i<obj.getPropertyCount();i++) { KSoap2ResultParser.parseBusinessObject(obj.getProp erty(i).toString(), getReminder); } call in another class public static void parseBusinessObject(String input, Object output) throws NumberFormatException, IllegalArgumentException, IllegalAccessException, InstantiationException{
how can I extract data from two different files but produce one output. For example, the first three columns are from text_file_1 and the last column (the last foruth column of the output) is from text_file_2.
I need to store the data of a bunch of objects of a particular class in files in a predefined directory. Later, I want to get all the files from the directory and turn them into the objects again. Ideally, I'd like to have one file per object and have the files be human-readable and editable without too much difficulty. The class used by the objects will likely be subject to change in the future, as well. To keep things simple, all the data members are either primitives, Strings, or arrays of them. What is the best library/API to use to deal with this situation? Or should I write my own classes for these operations?
I read into serialization, but I read that it doesn't deal well with classes that are frequently modified. I also found articles on Preferences, but none of the ones I saw seem to explain how to best handle reading and writing to and from multiple objects, especially when I don't know a prior all the objects that were written to disk.
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 have written a program (DOM Parser) that parses data from a XMl File. I would like to create an individual file with the corresponding name for each set of data parsed from the xml document. If the parsed output is Single, Double, Triple, I would like to create an individual xml file (Single.xml, Double.xml, Triple.xml)with those corresponding names. How do I create the xml files and give each file the name of my parsed data output?
I want to create an application wich can handle xml files ( display xml files's data on a html page) + insert those data into an oracle database.
I'm new to that, it a project for my internship. wich API is the most appropriate for that ( Jdom or Xstream or other), wich framework i can use ( there is only 3 IHM : connexion, upload file, display data, confirmation insertion data)?
I have my code in 3 different files using encapsulation (Data hiding) and i have 1 problem at the very end of my code in my if and else statement (very bottom) when trying to call the classes from the other 2 documents. I will put the code in 1st document to 3rd document.
// FIRST DOCUMENT public class CollegeCourse { //class name //variables String deptName; int courseNum; int credits = 3; double fee;

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap? Currently my program reads the data from several text files in a directory and the saves that information in a text file called output.txt. I would like to cache this data in order to use it later. How can I do this using the TreeMap Class? These are the keys,values: TreeMap The data I'd like to Cache is (date from the file, time of the file, current time).

I need to process 10000 xml files and verify and insert the data into database. I am loading all the files in the file object and iterating one by one. I am getting the memory issue. How to handle this?
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.

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've been staring at my code for the past few days and I just can't get it to work out. I'm trying to parse a DOM object with the following XML loaded:
I'm trying to get all of the attributes that I care about out of the <record> tags (date, event, etc ...) and stick the data in a wrapper class (DocumentData). If you run this, you'll see that it is close to working, but I'm having trouble getting the attributes in the <subject> and <return> tags (I need to get the errval and uid attributes).
I'm simulating temp/humidity values and want to separate the string value reported and parse each part (left and right) for their respective values. However, I'm having trouble figuring out how to parse the right hand side of this string value, I can get the left using split (shown below), but I think split removes the right hand side of the string value.

this is the error I'm getting..reached end of file while parsing. I think this is referred to as either an extra curly brace or that I am missing a curly brace but I'm not 100% sure.
I have to read this CSV file into an arraylist. Arraylist i call weight. The data in the csv file has 200 double values which is the weight of all the 200 bananas. Since the csv file is a string i guess I cannot create an double arraylist from scratch, but i have to parse the csv file afterwards, right? Well this does not work and ill show you the code in a bit, just need to state all my issues.
My second issue is how to be able to print out the the weight items (in this case bananas) next to the weight of the bananas taken from the array? This has to be done by constructor i assume? I just dont know how constructors work with arraylists.
Id like it to look something like this in the output window.
Banana 34,55 Banana 43,55 Banana 23,74
and so on (200 times)
so these are my issues, how to parse and how to print the arraylist weights and the item banana in the output window with constructor. Here is the code.
I have a String formated in the same way as package names:"com.darkchanter.code.NameValue"..Now I need to extract "NameValue" - the problem doesn't actually block my stuff, but before I write my own code, I Wonder if there is a function already available...
