How To Hide JComboBox Array Option
Jul 24, 2014
I'm trying to hide a JComboBox option depending if the a user has picked a certain option from a previous JComboBox.
.setVisible(false). doesn't work
String[] Dest = new String[] {"Select Destination","Crete", "Paris", "Croatia"};
String[] Accomodation = new String[] {"Select your Accomodation","Hotel", "Villa", "Bed & Breakfast","Youth Hostel"};
String[] Night = new String[] {" Select number of Nights", "7","10","14"};
final JComboBox<String> comboDest1 = new JComboBox<String>(Dest);
[Code] ....
I know setVisible isn't the way it's done but i don't know how to do it

{
switch(comboDest1.getSelectedItem())

I'm having an issue with using a JComboBox to select an item from a parallel array and displaying the correlating results in the same frame. Essentially, I have to add seven cities to a JComboBox drop down within a frame, select a city then display the population of that city in the frame with a label indicating the population. I have two issues:
1) my label text will not show up during execution unless I drag a corner no matter what width or height I make the frame.
2) I need to make the JComboBox selection correlate to the city population and display as a label, not having making that work using the getSelectedIndex() method.
I think I need to add an event listener for the combobox selection, not sure where to add that if that is the case. Here is my mess so far:
import java.awt.FlowLayout;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JComboBox;
[Code]....

I am trying to create a JTable and I want to implement an undo option in it. Is it possible that I store the table model at some part of the operation and later when i press an undo button or something, I can set the saved table model so that it will perform like an undo.

My code is already running. But the problem is, i don't want to see 0 denomination. like for example if i input 3.86 in (dollars).
dollars: 3
quarters: 3
dimes: 1
pennies: 1
so my problem is. it still showing 0 denomination like this:
dollars: 3
quarters: 3
dimes: 1
nickels: 0
pennies: 1
Currently using latest netbeans and if im correct we are using methods and class runner?.. Anyways here's the code..
for method:
package MyPrograms;
public class Mp3Method {
public int dollars(int dollars,int remainingAmount){
return dollars = remainingAmount / 100;
}
public int quarters(int quarters, int remainingAmount){
return quarters = remainingAmount / 25;
[Code] .....

I have eight panels that are one above the other and are the full width of the frame.
I would like to hide some of them some of the time and then "bring them back".
If I use panel1.setVisible(false) panel1 will disappear but then all the panels below it move up to take panel1's place.
I don't want that to happen. I want just a blank area where panel1 was.
Is there a way to do that?

I have a login window, which when sucessful will activate a new Applet/JFrame. The problem is that the login window remains in the background under the new JFrame. I want this to diappear. I want to either set the visibility to false, or close it.This is how the new window is started:
if(sucess.equals("flase")){
DBAccess dba = new DBAccess();
dba.setFname(fnameusr); //fnameusr
dba.setLname(lnameusr); //lnameusr
dba.main(null);
//LogIn.exit(0);
}else{
JOptionPane.showMessageDialog(null, "Your credentials were not entered correctly or you may not be authorised to access this system.");
System.exit(0);
}

As below code showing that you cannot directly access the private variable as i understood,
public class EncapsulationDemo{ private int ssn;
private String empName; private int empAge; //Getter and Setter methods
public int getEmpSSN(){ return ssn; }
public String getEmpName(){ return empName;

my code is ignoring the checkbox option when Iterating in loop like this:
<tbody>
<c:forEach items="${users}" var="user">
<tr>
<td><input type="checkbox" name="deleteFromList" value="${user.id}"/><input type="submit" value="Delete" name="action" ></td>
</tr>
</c:forEach>
</tbody>
The output of value="${user.id}" is retrieved from a DB, it looks like this:
Id Nombre usuario Email Fecha de registro Acción
1 isaac2 @2 1986-01-01 *Delete(input) *Here there is check box
2 isaac3 @3 1988-01-01 *Delete(input) *Here there is check box
Then depending of which check box I selected then the row by the side should be selected by id and deleted.But what happens is that doesnt matter which check box I select, always the first row is deleted. I understand that at the first iteration of the loop it just take the first id, it doest attach the id I have choosen to the row it belongs to

I have a jsp form that has a drop down option for a user to select. I would like to know how to have a pre-selected option that has been retrieved from my database or provide a default option if none has been selected by the user. My form allows a user to update a record in my database and what I need to achieve is when a user is updating an existing record they do not have to touch the drop down box if the do not need to change that option.
Here is my current form below form method
="POST" action='UserController?action=edit&albumId=${album.albumId}' name="frmAddAlbum">
<label for="album id">Format : </label>
<select name="action" selected=<c:out value="${album.format}" /> >
<option value="listUser">CD</option>
<option value="listUser">Tape</option>
<option value="listUser">MP3</option>
<option value="listUser">VINYL</option>
</select>

I understand the stack part of it, just not the loop, specifically how you give the user more than one option to input.
Implement a printer driver that handles incoming print jobs. The driver will behave in the following manner:
- Loop giving the user the following options: ADD print job, DELETE latest print job, and
QUIT
- Recording the following information from each job: computer name, document name, and
number of pages
- When the user chooses to ADD, add a new print job to the top of the stack
- When the user chooses to DELETE, pop off the latest print job and output to the screen
which job has just been deleted
- When the user chooses to QUIT, output the print jobs still in the stack (in order from top
to bottom)
- Output must include all relevant information for each job.

There is my code so far, on the line JOptionPane.showInputDialog(null, "Give us a word starting with "+text[i]+":", "tut", 2, image, ?, null);, eclipse gave me 2 extra arguments following the icon and I'm not sure what exactly goes into the 2nd to last, the "selectionValues" argument.
After checking the Java docs, it was apparent that the option buttons goes into the selectionValues argument, but is there a way to work past that if I would only like the default (OK, Cancel) buttons on my window? The school haven't taught us the method to create custom buttons and I doubt I would've been set something that was not taught.

I've a simple status bar in which I've several icons inside a HBox (ui drawn with fxml). These icons can be visibile or hidden due to some configuration properties in my app. I've a bind between some BooleanProperty and image.visibleProperty. The problem, as you can guess, is that when an icon in the middle disappears I've a hole. There is a property as in Android [URL] ...., that hide the node and collapse its space?
