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
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:

Tried it, I get red line under it, tried to do "jframe1 jframe1 = new jframe1(variable);
jframe1.setVisible(False); still failed. all I want to do is open a different jframe which I got that to work but cant hide show me how to do it without having to emend my code I want to be able to do is in same style.

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.
Currently using latest netbeans and if im correct we are using methods and class runner?.. Anyways here's the code..

Hiding the column but not removing , because i need to bring this column id to the next screen, only i do not want to show the column but internally it has to take the value to navigate the screen, but if i use below code, i am getting null pointer exception,
I've made a login system with a username and a password. The password is visible and I wanna hide it, how do I do that? Here is my code (have used swing);
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); }
I'm trying to write a program where the user has the option to enter either an int or double but whatever input I enter just gets cast to a double. Do I even have the right Idea by using if else statements?
import java.util.*; public class VS { public static void main(String[] args) { Scanner Input = new Scanner(System.in); System.out.println("Please enter a number"); if (Input.hasNextDouble()) {
I am trying to do a rock, paper, scissors game, but when i choose for example, it shows what i have typed. So how do i hide text form showing in the console?
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;
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.

I have to create 3 JLabel for Option, Square and Direction. Well, I did but its not in the right place. It should be in the right Panel but i did change the code so its in panelRight1 but its still not changing?

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.
SceneBuilder 2.0 on my computer shows no onAction for ChangeBox. How to get around this? Several of the Java coding options listed online do not work with JavaFx 2 and SceneBuilder.
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?
