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);
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 license header, choose License Headers in Project Properties. * 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 {
I am facing a problem while executing a task. My task is to make such a code which will search for my source code file (abc.java) in all directories and then displays the code in textarea inside frame and along with that i also have to display the path of the file in text field. I have coded something but i am really not getting anywhere near my task.
I would like to build a GUI where by I can import a text file and interrogate certain values and then display them in a window. Thing is I would like to know what window type that will support this. i.e Panel,internal frame,dialog box.. etc etc... I am using Netbeans.
I am trying to upload the text file in specific location in my disk but when I open selection window it displays all type of files while it should display the files only having .txt extensions
I am writing the code below,
<%@page import="org.apache.commons.fileupload.*,java.util.*,java.io.*"%> <!DOCTYPE HTML> <html> <head> </head> <body> <% // JSP to handle uploading // Create a new file upload handler
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

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'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?
When I am entering the student name , his/her details should be retrieved from database by servlets and the data to be print in jsp pages this what I want But I am unable to display the data from database in jsp pages .
Need to display data in a table - no of columns are fixed, and rows may vary based on the data available in DB.Display tables in horizontally and 2 tables per row. If it exceeds 3 it should display in next rowsample format to display attached in attachment,Using JSF 2 & richfaces 4.0.
I'm supposed to take this truth table and alter it so it displays 1's and 0's instead of true false. I'm assumed to do this I would just need to change the variable type and replace true and false with 1 and 0 but every way I try this does not work.
//a truth table for the logical operators.
class LogicalOpTable { public static void main(String args[]) { boolean p, q; System.out.println("P Q AND OR XOR NOT"); p = true; q = true; System.out.print(p + " " + q +" ");
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?
I have an application that displays a GUI and this GUI displays a table with several columns and rows. I have a class that extends DefaultTableModel. I wrote the code that displays the GUI. When the database table changes, how would I updated the GUI dynamically? Do you have any sample code that does that?
Budget program. Here is my situation, I have 2 tabs in a GUI, one tab adds a transactions when the add button is clicked, and in the other tab displays a table showing all the transactions. In my code, I want it so that when the user chooses a deposit(combo box variable name = cbType, indexnumber for deposit is 0) it will add to the total and when the user chooses withdraw(index number is 1) then it will subtract it from the total. Here is the code.... (note as well, the code also adds a new row to the table)
So when I tested the program with 2 transactions, the first transaction was a deposit and the 2nd transaction was a withdraw. The end product was that both amounts were subtracted from the total. When I did a withdraw first and a deposit second, the amounts were both added together.
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...
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 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();
I have been trying to get my radio buttons to display text when they are selected in a textbox but for some reason no matter what i try it wont display. Here is my code i have removed my attempt to get the action listener working.
package listVsSet.Desktop.copy; import java.awt.BorderLayout; public class ListVsSetGui extends JFrame { private JPanel contentPane; private JMenuBar menuBar; private JMenuItem mntnListVsSet;
int lottoNumbers1 = Integer.parseInt(txtLotteryNumbers1.getText()); int lottoNumbers2 = Integer.parseInt(txtLotteryNumbers2.getText()); int lottoNumbers3 = Integer.parseInt(txtLotteryNumbers3.getText()); int lottoNumbers4 = Integer.parseInt(txtLotteryNumbers4.getText()); int lottoNumbers5 = Integer.parseInt(txtLotteryNumbers5.getText()); //int lottoNumbers6 = Integer.parseInt(txtLotteryNumbers6.getText());
So I want the method getDisplayText of d to be returned as long as the for loop runs. When I do this I get a compile time error to enter a return statement. I am currently trying to fix it by returning an empty string, yet this doesn't seem the right way to go.
public static String displayMultiple(Displayable d, int count) { for(int i = 1; i <= count; i++) return d.getDisplayText(); return ""; }
