There are 8 JCheckboxes, which are already added to panel and aligned in group layout. From which, I have selected one JCheckbox. Then the resultant GUI should contain only remaining 7 JCheckboxes and selected one should temporarily removed or hide from GUI . Is it possible? If so, how?

I've almost finished building an Editor in Java, but i'm a bit stuck on creating a JCheckBox that saves your credentials (as in password only) . I would like it to be on a JPanel under the password input box and above the Login and Register buttons.
Code:
Login.java (Main class for this problem)

The main thing here is using GridLayout, which is what im currently working with but can't seem to get it under the password input box.. check: [URL] ....

But my problem is inside the JTextArea the answer from a JTextField and JComboBox is also there, and they should be appear in a parallel. I attached the physical appearance of the GUI.

I'm displaying a table with several read-only pieces of data, and a checkbox field that toggles the row color. The background color for the checkbox is not toggling correctly. I put together a SSCCE:
import java.awt.Color;
import java.awt.Component;
import java.util.ArrayList;
import java.util.List;
[code]....
If I comment out the Nimbus look and feel, it works as expected. I googled this problem and found one possible solution on Stack Overflow. Their suggestion is:It's a bug in the synth-installed renderer, quick hack is to force the rendering checkbox opacity to true: ((JComponent) table. get Default Renderer(Boolean.class)).setOpaque(true);
I tried using this line and setting the opacity to true, but it renders the background white. I'm using Java 1.7.0_25.

I would like to get a checkbox within a table to fire an event when it's clicked rather. I gave tried putting in a TableModelListener but the the event only seems to trigger when I click on another column (as if the table is waiting to see if I will change my mind) before moving on.
I have also looked at the setValue of the TableModel itself.
Do I need to put an ActionListener on each checkbox or have I missed something ?

I'm currently writing a small program, where I need to save data into a Defaulttablemodel in a jTable.I have to save the name, a number and the email-adress.I added a button which opens a new JFrame and there I need to change the email and/or the name.My current solution is far from good: No matter which row I select, i can only update the "newest" row (last created). How can I visualize the values of the selected row (out.println// or whatever) so I can go further and overwrite these values.My Code when I click on Update:
int zeilenwahl = jTableStudenttab.getSelectedRow();
// System.out.println(jTableStudenttab.getSelectedRow());
if (zeilenwahl != -1) {
this.setVisible(false);
new Bearbeitung().setVisible(true);
} else {
JOptionPane.showMessageDialog(rootPane, "Zum Bearbeiten Zeile auswählen");
}
Here is where the mistake is (probably)
public Bearbeitung() {
initComponents();
jTextFieldvorname.setText(Student.vorname);
jTextFieldnachname.setText(Student.nachname);
matrikelstring = matrikelstring.valueOf(Student.matrikelnummer);
jLabelmatrikelwert.setText(matrikelstring);
jTextFieldemail.setText(Student.email);
}

I was wanting to select an item in a comboBox and display it in a text field but all it's doing at the minute is retrieving the first item in the comboBox and placing that in the txt field
String value = (String) comboBoxEnv.getSelectedItem().toString();
if(comboBoxEnv.getSelectedItem()!= null){
txtTo.setText(value);

I just learned about 2D arrays and am still trying to get a grasp on the concepts. I'm a little confused by how you return all the values in a row to add up and display the sum if the row is entered by the user.
import java.util.*;
public class RowSum {
public static void main(String[] args) {
Scanner s = new Scanner (System.in);
int userpick = 0;
int sum = 0;

I need to somehow compare the random color chosen from the color array and the random name selected from the name array. I know how to compare to entire arrays of the same type such as integers. How to go about this with two different arrays. I thought maybe I could parse the color array selection to a string but had no luck with that either.
Problem #1: Design and implement an Applet that plays a simple game to teach a child to read. The game displays a picture on the left hand side of the Applet and a word on the right hand side. Below the pictures are two buttons for the child to click--one if the word matches the picture, the second of the word doesn't match the picture. Display an error message if the child is incorrect (or play a sound). Display (or play a sound) display words of encouragement if the child chooses correctly. Add a loop so the child can keep playing.

I want to synchronize a List<String> with the selected items of a ListView. In the real project, I want to synchronize the selected items of a TreeView and the selected images of a galery (custom control).
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.collections.FXCollections;
[Code] ....
In most cases, the program works as expected but sometimes there are some issues.
- For example, when I launch the application and select all the items with Ctrl-A, the event { [One, Two, Three] added at 0, } is fired so the list of strings contains incorrectly 4 elements [One, Two, Three, One].
- Another example, when selecting all the items (with Shift+End), two events are fired { [One] removed at 0, } and { [One, Two, Three] added at 0, }, that's correct. But when I remove the last element with Shift-Up, 3 events are fired { [Two] removed at 1, }, { [Three] removed at 2, } and { [Two] added at 1, } and an exception is thrown:
java.lang.IndexOutOfBoundsException: toIndex = 3
at java.util.ArrayList.subListRangeCheck(ArrayList.java:1004)
at java.util.ArrayList.subList(ArrayList.java:996)

I'm trying to add filtering content in ListView by selected date from DatePicker. Every position(movie) has it's emission date saved, so when you choose date that you're interested in, it will show just matching titles. I was trying to use this solution:
@FXML
private void initialize() {
titleList.setCellFactory((list) -> {
return new ListCell<Movie>() {
@Override
protected void updateItem(Movie item, boolean empty) {
super.updateItem(item, empty);
[Code] ....
But when I add new position and change date, that I'm filtering by, every title disapear and don't reload. How can I make this work with every change?
