Property Files That Used To Configure The Application Can Be Stored In Jar File?
Dec 22, 2013
I already used properties file without problems for localizing information. In that case the property file was stored as a resource in a package; and I used the Class ResourceBundle to manage the operations and the ClassLoader to access to the file.
Actually I need to use property files “To save the configuration of the application”.In this case I need also to update information stored inside the file.property, and I used the same procedure as before to manage it (ClassLoader to get data- also for writing).
I had problems in this case: that the data was never modified inside the properties file. I investigate, and now I think that the problem comes from writing in the property file that is located in the .jar file. For what I know, it is impossible to change resources putted in the .jar files.
I found a solution: to store the properties files out the jar files; and in this way all is good. But it would be more comfortable to store inside.
My question is : if a file property used to “save the configuration of the application “ have to be put out of jar, or is there another way ??

Any documentation that deals with assigining an icon to your application? I have tried the:
"stage.getIcons().add(new Image(this.getClass().getResourceAsStream("myicon.png")));"
Code as suggested on the web. It looks like this changes the icon in the window decoration only, which doesn't actually show on my Ubuntu desktop with Unity. What I really want is a custom icon for when I alt-tab through open applications. Currently it shows the default grey question mark. How do I assign an icon to the application.

I have this program to see the occurrences of a character in a string stored in a text file. My text file has the following contents (as shown below):
P-P-N-N-L-V
N-R-U-S-R-Q
K-Q-E-L-E-A
A-J-B-G-E-F
F-E-L-Q-R-R
U-F-J-V-I-M
P-I-Q-K-B-K
U-N-L-F-O-B
M-A-N-M-H-O
P-Q-J-D-N-I
G-U-O-D-F-I
Q-M-M-B-C-Q
N-B-I-L-E-J
S-A-T-Q-H-U
C-L-G-U-J-M
R-P-V-M-A-A
C-R-A-V-L-B
M-U-Q-K-M-Q
E-I-C-H-V-J
J-N-N-K-R-P
As you notice, each character is seperated by a hyphen (serving as its delimiter). I want to only go through 10 lines in the text, instead of all 20 of them. So, I wrote the program in such a way that I intend to reach into the indices of each character in the text file. Since there are six characters in each line so that means there are 6 indices - and there are 10 lines I only want to go through. So, 6 indices times 10 lines equals 60 indices. Hence, there are only 60 indices I need to go through. In that manner, it's like I have gone through only 10 lines through that way.
It compiled perfectly fine but upon running it, I ran through an error in the black DOS screen that says
"java.lang.ArrayIndexOutofBoundsException: 6 ".
How do I work around that?
The code I wrote is shown below...
import java.io.*;
import java.util.*;
public class hotandcoldclusterdeterminer_test {
public static void main (String args [])throws IOException {

I am trying to write to a text file with information stored like this.
brick 500
stone 500
And so on. Here is the code I am using to write to the file.
switch(record){
case "brick":
x.format("%s%n", "brick " + value);
closeFile();
break;
case "log":
x.format("
%s%n", "log " + value);
closeFile();
break;
When I write like this, putting deletes the first line. What I can look into or other functions that would be useful?

I have created an application that I wish for people to be able to run from command line, like so:
java myApp [filename]
Problem is my application uses functions from 3 .Jar files.
Here is how my folder(Assume it is called MyApplication) currently looks:
Application(folder)(contains .class files + source code)
jar1.jar
jar2.jar
jar3.jar
Manifest.txt
I understand I need add some information to the Manifest.txt file but I am struggling in adding stuff to it in the correct format.
Assuming the above folder is called my MyApplication, what I need to put in the Manifest and how to build it all as a Jar File.

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.

ensureFileIsVisible not working.
JFileChooser fileChooser = new JFileChooser();
fileChooser.setCurrentDirectory(new File(currentDirectory));
File f = new File(currentDirectory);
ArrayList<String> names = new ArrayList<>(Arrays.asList(f.list()));
for (String s : names)
if (s.startsWith(yearofIssueTXT.getText())) {
fileChooser.setSelectedFile(new File(s));
fileChooser.ensureFileIsVisible(fileChooser.getSelectedFile());
break;
}
int result = fileChooser.showOpenDialog(addNewCoinBody);
The file is not visible because it is at almost the end of the files in the directory. I want the filechooser to automatically scroll so that the file is seen in the list.

I was just wondering how would I create a jar file that would open 3 other jar files when I open the jar file with my batch file it and when I type stop in the batch file it will out put the stop command into all 3 of the other jar files.
This is for my Minecraft server so I can launch them all at the same time and inStead of having to enter the commands in all the server batch files I just have to do the command in 1 I know their is things like multi craft to do this but I want the code so I don't have to use multicraft.

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?
