I'm supposed to write a GUI application letting the user enter a file on the text field and display its hex representation in a text area and vice versa.
Here's my code:
/*

* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package hexconvertor;
import java.util.*;
import java.io.*;
public class HexConvertor extends javax.swing.JFrame {
[Code] .....
It's not doing anything, I don't understand why.

I think I need to save the file into an object but I cannot seem to figure out how. I tried to save it into a string array but that did not work either. I have been working on that section for three weeks and cannot get it to display correctly.
public class DVDList2 {
private static void CreateGUI(){
File file = new File("C:UsersaprildesktopDVD.txt");
JTextField txtName, txtSeason, txtSearch, txtMain;
JFrame frame = new JFrame("DVD List");
txtName = new JTextField(20);
[Code]...

I have my below Swing GUI code in which I want to read and display some contents present in text file say (test.txt) which is located in my local disk (C: est.txt). My pane tab 2 is divided into two halves horizontally. How can I read and write the test.txt file contents under the tab tab2 in the first half of the pane(where currently it is 2 written)?
Sample test.txt present in my local hard disk location
username:test1
Password:test1
DataBasename: testDB
CODE FOR TABBED PANE
import javax.swing.*;
import java.awt.*;
public class SplitPaneExp {

I have to write a gui program where I can enter a file name and then it gets displayed in a text area when I click Open. Conceptually, I do not get this. I was thinking of appending the text file into a string or something, but I guess I'm confused on how it all works and how I can open the text file. Not asking for the code, but just a compass or something.

I cannot use menu selection 4 5 6 7 8 9 10 ... Why NO_EXIT has been declared and used in defining the contents of the map array, rather than just directly using the value 99999 in the map array definition
I don't understand map[][], objectName[] and objectLocation[]
package Assignment;
import java.util.Scanner;
public class GameWorld
{
// the map array holds details on which paths lead to which other rooms. NO_EXIT indicates no valid exit.
// each element holds the details of all paths leading out from a single-room in the order n ,e, s, w, ne, se, sw, nw
private final int NO_EXIT = 99999; // indicates that there is no exit in that direction
private int map[][] ={{NO_EXIT,NO_EXIT,NO_EXIT,1},{2,0,NO_EXIT,NO_EXIT},{NO_EXIT,3,1,NO_EXIT},{NO_EXIT,NO_EXIT,NO_EXIT,2}};

I have an addressBook GUI where I have a JList that populates with the contacts names, and once I double click a contacts name I'm wanting to fill the textfields with the contacts corresponding data.
ex) ContactType: Family (enum), Name: Zoidberg, Address: 111 Space Drive, City: New York City, etc...
I've got it to where I select open from the JMenu, it populates the JList, but once I select a contacts name, all the textfields are populated, but only with the contacts name
ex) Name: Zoidberg, Address: Zoidberg, City: Zoidberg, etc....
What am i doing wrong here, and how can i fix it to where it fills out the correct data?
Here's my code so far:
public class AddressBookGUI extends JFrame {
private final int WIDTH = 450;
private final int HEIGHT = 300;
private JLabel currentlySelected;
private JTextField contactTypeTextField;
[code]...
I'm certain the logic is messed up near the end where i set all text fields to the index, because no matter what field i want to fill it's at it's going to set it to whatever index I select, but I don't know how to fix it.

I am having the hardest time trying to figure out how to display an array in a 1-window GUI.
I can display 1 book separately, by basically ignoring the array and creating a new object for each book, but I need all 5 books to display in one window, and that's where I'm lost. I'd really like to use the arrayI built to generate the books in the GUI. The information of each book appearing horizontally, and the different books appearing vertically.
// Bookstore.java
// This program displays information on multiple books
/* Currency Formating Import */
import java.text.NumberFormat;
import java.util.Locale;
import java.util.Arrays;

I've chosen to build a GUI that will initially display a window with 'x' number of buttons for different subject areas of physics (kinematics, waves, sound, circuits...etc). I would like to use an Actionlistener for each button so that when its pressed, the JFrame will extend a sidepanel or expand the JFrame with a new JPanel that contains variable Jtextfields so the user can enter data to calculate.
I'd like to know if its possible to do this with the JFrame or should I just open a new window altogether? I have some other features I plan to add to the program, but this is where I am right now.
how difficult is it to add a banner image and imageIcon? By banner image I mean create a Jpanel that will contain a header for the window and will have some cool physics jpg image.

I'm working on a simple text editor, and I'm currently saving the contents of my JTextPane in a file using an HTMLEditorKit (text is a JTextPane):
private void save() throws IOException {
int returnVal = fc.showSaveDialog(window);
if (returnVal == JFileChooser.APPROVE_OPTION) {
StyledDocument doc = (StyledDocument)text.getDocument();
HTMLEditorKit kit = new HTMLEditorKit();
BufferedOutputStream out;
[Code] ....
The problem I'm having is that after opening a file that I saved, it does not display (if I disable text/html, it displays the entire html code, but when I re-enable it, nothing displays at all.) Am I loading it wrong, or am I setting the JTextPane's text incorrectly? Or is it, perhaps, another error that I didn't catch?

So, Iv'e been trying to make a simple Text Based RPG with Java, and it is going quite well, and my friends want to play it too but they aren't very tech savvy, so it's hard to tell them to get an IDE or use the CMD, so I wanted to know if there was a way to make my text-based game into a window, like using JFrame or something. All i need is a window that displays the text, and a bar on the bottom that lets the user input what they want (Kind of like a CMD).
I want it sort of like this window: This Pic

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?

Write a class named FileDisplay with the following methods:
1.) constructor: the class's constructor should take the name of a fil as an arugment.
2.) displayHead: This method should display only the first five lines of the file's contents
Here is the following code I have made so far
import java.io.*;
public class FileDisplay
{
private String filename;
public FileDisplay(String Filename) throws IOException
[Code] ....
First, in my constructor I have taken in an argument and used that argument to open up an output file. Meanwhile, I'm trying to work n the displayhead method to print out information and to read data to. I haven't opened up my input file yet, but I'm not understand how can I read a print data to an output file. in
public void displayHead()
{FileWriter file=new FileWriter(Filename)}
do I make create another instance of the filewriter class to output data?
In simple words, suppose to I want to display some messages on my output file in the displayhead function. Since I already have opened up the file in the constructor, how do I combine that in this method...

I am checking how to do following task.
01. pickup the selected text file and read the line by line and output the text in to visual text pane.
what i did:.
01. I wrote code that read the text file and output in to jave console/ also some of the interface.
the code read txt file:
Java Code:
String fileName = "C:/Users/lakshan/Desktop/lawyer.txt";
File textFile = new File(fileName);
Scanner in = new Scanner (textFile);
while(in.hasNextLine()){
[code]....
so it will read any text file dynamically and output to the text pane in interface. I think scanner code must be execute after the select the file from the browser and set the scanned result in to variable. then later out put the var as string in some jswing component?

I made the program below in java and compiled with javac command in Window7 (64bit machine). It simply post my machine IP and Mac address to my server application.
When i run this script with java as >java Macregister
I get what is expected, the program runs well on my machine.
When I try to run it on other machines (Win8 - 32 Bit) I get error message and nothing works.
My problem is 1) to make it compatible for all machines 2) to convert it into JAR application so that it is self executable on different machines.
I am a new to Java and am struct,
import java.net.*;
import java.io.*;
public class Macregister{
public static void main(String[] args) throws Exception {
InetAddress add=InetAddress.getLocalHost();
NetworkInterface network = NetworkInterface.getByInetAddress(add);
byte[] mac = network.getHardwareAddress();
StringBuilder sb = new StringBuilder();

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

I am in the middle of creating a chess application, and am currently working on laying out a list of moves on the right of the actual board. Specifically, I want to have a JLabel that says "moves" on top of a JList that contains the moves, on top of two buttons, labeled "<" and ">" respectively, to which I will eventually add functionality to take back and un-take back moves. Currently I have the first two parts down, but when I add my buttons,the other components are getting messed up.
I have all of these things in a vertical BoxLayout inside of a JPanel with a fixed width of 70, and a height that varies according to the size of the window (I overrode the getPreferredSize method of the JPanel). The two buttons are within their own JPanel with a grid layout with one row and two columns. Then I basically just add the moves list label, the movesList, and the panel housing the buttons to the larger panel, in that order.
However, I am encountering two problems. One, the buttons display the text "... " instead of "<" and ">" as if there is not enough room, although I'm pretty sure three periods take up more space than one less than or more than sign. The next is that, without the buttons at the bottom, the label reading "moves" is appropriately centered (or left aligned, I can't tell which) over the movesList, and you can read its whole text. However, when I add in the buttons at the bottom, the label of the top shifts over to the right and then reads "mov..." because it has run out of room.
Here is my code:
//move list
movesListLabel = new JLabel("Moves");
//the components for the actual movesList come from another class with an object called pen, but I don't think this is the problem
listModel = pen.getListModel();
JList movesList = pen.getMovesList();
JScrollPane listScroller = pen.getMovesListScrollPane();
