Cut / Copy / Paste / Delete And Select All Are Not Working

Mar 22, 2014

I am quite new to Java programming. I'm actually taking a class and I have an assignment due tonight. The program below compiles and functions correctly for the most part. It is supposed to be a simple GUI Text Editor with Edit and Format functions. Of the functions under the "Edit" menu, only word count actually works. Cut, copy, paste, delete, and select all are not working.

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.io.*;
import java.util.*;
import java.util.StringTokenizer;
import java.util.regex.Pattern;

Delete From ArrayList

Dec 7, 2014

I've this "program" that shall manage to register a dog, show a list of all registerd dogs and delete dogs from the list.. And I'm stuck at the latter one. So I've to classes, one for the dog and one for register/program. This is my main program

package hundRegister;
import java.util.Scanner;
import java.util.ArrayList;
public class HundProgram {
private static Scanner tangentbord = new Scanner (System.in);
private static ArrayList<Hund> hundlista = new ArrayList<>();

[Code] ......

So, when I enter a name on a dog that exist on my list, it just jumps down to } else { and write that dog can't be found even if I write the exact name on the dog.

I can't see what I'm doing wrong, been trying out different methods now.

EJB / EE :: Same Listener MDB For Different Jms Queue?

Feb 21, 2014

Is it possible to define the same message driven bean as a listener to different queues?

The goal being to define different redelivery configuration for different kind of messages, but handle them all through a single deployment MDB for unity/entity purposes.

The other option is to have many MDBs targeted to the same source code.

Modify And Delete Functions

Apr 4, 2014

I am writing a program for my Java class and I have every function of the program working aside from the modify and delete button. I'm not sure how to make them work. The course material doesn't cover these functions at all.

Here is what I have so far.. which is practically nothing. If I need to post any other code I will, I just don't want to post more than needed because going through unnecessary code can waste time.

public void actionPerformed(ActionEvent e)
{
inventoryTotalField.setText(String.valueOf(genre[ArrayIndex].getInventoryTotal()));
//add button functions
if (e.getActionCommand() == "First")//if first button is clicked
{
ArrayIndex = 0;//set array index to the first element in the array
setFieldValues(); // display dvd info on the form

Implementation Of Immutable Queue

Nov 12, 2014

The following codes shows an implementation of an enqueue function of a FIFO immutable queue, and the output result shows the String "c".

I don't understand why since I expected it should be null.

The head and the tail of an ImmutableQueue Object are two separate queue, and each time I call the enqueue function, it just return a new object with a new tail, however, the head is not modified except the first two times I call the function.

Therefore, I expected head.next.next should be a null element, but the result is not like that.

public class ImmutableQueue<E> {
private int size =0;
public Queue<E> head;
public Queue<E> tail;
public ImmutableQueue(){}
private ImmutableQueue(Queue<E> hd, Queue<E> tl){
head=hd;
tail=tl;

JSP :: How To Delete And Insert Data Into Two Different Tables

Jun 2, 2014

I am creating a portal using JSP and MySQL with eclipse IDE. I have a scenario where data is stored on draft table and is retrieved then stored on another table. I need the entry in the draft table to be deleted after the insertion. When I tried to run the code it redirects to success page but makes no impact on database(neither inserts not gets deleted).

<%@ page import="java.sql.*" %>
<%@ page import = "java.util.Date,java.text.SimpleDateFormat,java.text.ParseException"%>
<html>
<head>
<title>JSP Processing</title>

JSP :: Delete Database Record With JQuery?

Nov 4, 2014

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String delete = ("DELETE FROM anagrafica WHERE Nome = ? And Cognome = ?");
ConnectionManager cm = new ConnectionManager();
String Nome = request.getParameter("nome");
String Cognome = request.getParameter("cognome");

[code]....

and this is my JSP.The problem is easy, when I click on the grid for deleting the record two things happen, or the record is deleted only on JSP but not in my Database or Nothing happens even on my JSP, it is because I don't know how to get values from my jsp and send them to replace the ? in my delete query I tried even to give a name to the <tr> which contains Name and Last name but obviously i guess it works only for input type ex. Textbox.

JTable - Button In Table To Delete Row

Feb 16, 2014

My programms is working perfectly except for one little detail that annoys me. I have a JTable with a button on the first column that allows to delete this row from the table. Its working well except when I try to delete the last row of the table, the button stay there and then the table freeze and i can't delete any rows because i receive a "Out of bound Exception" . But, when I use the command table.getRowCount());

Before and after the removal of the line, the table "knows" that a line was removed but as i said, the button stay there. The screenshots in thumbnails show the situation before and after clicking the button next to the "Year" cell.

It's good to add that i'm adding rows in the table from a button outside the table.

Heres my code:

Main.java

static String [] title = {"X","Nom","SRM","Rend.","%","Kg",};
static Object[][] contenu;
static DefaultTableModel model1 = new DefaultTableModel(contenu, title);
static JTable tableauGrains = new JTable(model1);
 tableauGrains.getColumn("X").setCellRenderer(new ButtonRenderer());
tableauGrains.getColumn("X").setCellEditor(new ButtonEditor(new JCheckBox()));
ButtonRenderer.java

When To Delete Newly Created File

Jun 8, 2014

I have a method that checks to see if a file exists, if so, it reads the data contained therein, if not it calls another method then exits.

public void checkLoadPreviousStationStatus() throws FileNotFoundException, IOException,
ClassNotFoundException, EOFException, TempArrayOutOfBoundsException{
File f = new File(staFileName);
//if station file already exists load the info
if(f.exists() && !f.isDirectory()){

[Code] ....

My question, do I need to delete this file before exiting the method f.delete();? If not, what happens to it when I exit the method?

Memory recalled from a long ago taken c++ class: It's just reserving a memory location that will or will not be used isn't it? If nothing is stored in that location the reservation goes away right?

Base Form For Add / Edit / Delete

Sep 7, 2014

I have been developing what I intent to be a base class for several forms that will allow the user for adding / editing / deleteing records. These records could be customers, products, suppliers etc.

I have designed a basic form that has an add, edit and delete button. For the add button, I would want to clear all the values in all of the controls (textboxes, combox etc) in preperation for adding a new record.

My question is this. Is this something I should do in the base class OR should it be handled in the classes that will extend from the base class? Perhaps if the controls were datalinked to the data they will clear themselves (I haven't got that far yet so I dont know). I thought maybe I could write code in the base class that could loop through all of the controls and call this from the extended classes.

Print Queue Using Priority Q Simulation?

Nov 28, 2014

I have a class "ExecuteJob" which has Print Q in the form of Priority Q.

You can keep adding job to the Q by calling one of the method in the class. However, and object cant do things simultaneity can it? While im adding a new job to the print queue, can it be executing and existing job in the print Q.

To achieve that, I would need to implement process and threads? I believe am I right? So that adding a job is independent to being removed?
