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 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 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.

I am new to JSP . I am Using Jdeveloper UDI to create JSP Pages.
My main idea in creating JSP to display data from one or more tables.
I created 2 pages called Serverpage.jsp and Messagecount.jsp and it is working fine as expected,
Now i want to create home page and it should also have left navigation menu and it should contain MessageCount and MessageStatus.
When i click on Messagecount or MessageStatus my home page should refresh and have to display new JSP page (MessageCount.jsp or Serverpage.jsp)
Here is my JSP pages
Serverpage.jsp
<%@ page contentType="text/html;charset=windows-1252" isELIgnored="true"%>
<!--<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>-->

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)
//add button clicked
private class BtnAddActionListener implements ActionListener {
public void actionPerformed(ActionEvent arg0) {
((DefaultTableModel)table.getModel()).addRow(new Object[]{
cbMonth.getSelectedItem() + "/" + txtDay.getText() + "/" + cbYear.getSelectedItem(),
cbCategory.getSelectedItem(),
[Code] .....
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.

HTML Code:
import java.util.Scanner;
public class BellmanFord {
private int distances[];
private int numberofvertices;
public static final int MAX_VALUE = 999;
[Code] ....
I am trying to display two types of table one with initial cost and another one with new cost. Based on the java code here i already have one table but don't know how to display another table.
Attached is the sample output that i am aiming for. The output table for the above code is:
Enter the number of vertices
6
Enter the adjacency matrix
0 4 0 0 -1 0
0 0 -1 0 -2 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 -5 0 3
0 0 0 0 0 0
Enter the source vertex
1
distance of source 1 to 1 is 0
distance of source 1 to 2 is 4
distance of source 1 to 3 is 3
distance of source 1 to 4 is -6
distance of source 1 to 5 is -1
distance of source 1 to 6 is 2

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 developing a product where the client needs to display the content of XML in a JSP page. This XML will be extracted from database and will be temporarily sotred in a String object and will then be flushed to JSP page for display. This was working fine unitl now. But now the customer wants display each tag with one color. attribute in another color and data in another color.
For ex: <?xml version="1.0" encoding="UTF-8"?>
this should be displayed in one color. Then
<ichicsrmessageheader>Data</ichicsrmessageheader>
In the above one the tag should be displayed in one color and "Data" should be displayed in another color
<organisation operationtype="1">Data</organisation>
In the above sample tag should be in one color and attribute should be in one color ex: red and value of the attribute should be in another color ex: blue and "Data" should be in one color ex: green.
Here is the sample screen shot of how xml should is currently being displayed.

I'm trying to work out how to get a string from a servlet in to the JSP, The code I thought would work was as follows.
request.getSession().setAttribute("test", "this is a test");
request.getRequestDispatcher("C:myjsp.jsp").forward(request, response);
<%
String s1 = (String) session.getAttribute("test");
%>
<%= s1 %>
This is returning null ...
I have tried a few examples and followed a few tutorials but I keep getting null or nullpointexceptions.

I am new in XSLT and I started to support an application which has the servlet below. Which are the patterns in this servlet related to XSLT? Beyond the basic methods get and post, I didn't understand the purpose of too many methods. Obviously I can debug but I can figure out every purpose because it is not clean code: at least when I compare with much more straight forward servlets that I have supported. It seems that who has developed this application has used some common practice of wrapping DOM and SAX methods.
package jsp;
import My_App.ConfigAdapter;
import My_App.management.UserHandler;
import My_App.queue.PanHandler;
import java.io.ByteArrayOutputStream;
import java.io.File;
