jProgressBar with Threads for Database data Insertion

I'm trying to implement a JprogressBar to show the data insertion progress.
Basically the user select how many data sources will be imported to database.
With this parameter the main program Start a method to list those parameters and with a foreach loop it calls the insertion Thread and the ProgressBar update Thread.
for (Maquina i : m.listar()) {
//Passing to Import Thread the object with the data and a Date parameter
ImportarDados imp = new ImportarDados(i, jDateInicial.getDate());
//Calling progress bar update Thread with the progressbar itself and progress parameter
BarraDeProgresso bp = new BarraDeProgresso(progresso, progImportacao);
imp.run();
bp.run();
}
The threads kinda work on their own, but the result is not the one I want, cause the data is being imported and the progressbar is being updated, but it is being update to 100% after all data is imported. I need to update the progress bar as long as the import thread finish the importation for each (Maquina i) object.
If it is necessary I can provide the threads code...but i don't know if this calling method can provide the result I want. Searching on the forum i found something about EDT and i think it is the problem that the bar is not being updated. Can you guys help me solving this?
Minimal and Verifiable example:
My code is pretty short. The code generated by netbeans is huge, sry for that.
That code simulate my problem. The windows is refreshed only after the for loop is finished. But the BarraDeProgresso thread is running at the same as and SysOut some info...

Your current code creates no background thread. Yes you've got Runnables, but you call run() on them, meaning you are calling them on the Swing event thread. When you do this, you block the event thread, effectively freezing your program. Instead, you need to:
Create a true background thread by passing your Runnable into a Thread object's constructor and calling start() on that Thread.
Not mutate Swing components from within these background threads
Or use a SwingWorker as per the Lesson: Concurrency in Swing which will help solve both of the above issues.
For an example of use of a SwingWorker, please see:
import java.awt.Dimension;
import java.awt.event.ActionEvent;

ActionListener class doesn't get triggered for CheckBox

I am creating this software for a project and what i did was i created a method "Salad" here what happens is user can select maximum number of 2 salads.the names of the salad are coming from the database and i created checkboxes dynamically.
This works fine and I can get the values and insert it to the database.so then what i wanted was to update the inserted row.i created a method to setselected() the all the check-boxes that user selected before. so as i told above i created this method to select maximum no of 2 check boxes .when i try to insert it works fine..but when i try to update that ActionListener does not work.
I am using setSelected(true) in constructor that ActionListener is not triggering. What should I do this in the Salad() ??
public void Salad()
{
int count =0 ;//to count rows in result set
String sql="Select name from foodmenue where type='Salad' and menue='"+selecmenue+"' ";
try {
pst=con.prepareStatement(sql);
rs=pst.executeQuery();
while(rs.next())
{
count++;
}
if(count!=0)
{
rs=pst.executeQuery();
JCheckBox [] a=new JCheckBox[count];
jPanel7.setLayout(new GridLayout());
int x=0;
while(rs.next())
{
a[x]=new JCheckBox(rs.getString("name"));
a[x].setName(rs.getString("name"));
jPanel7.add(a[x]);
a[x].setVisible(true);
a[x].addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
if( e.getSource() instanceof JCheckBox){
String s=((JCheckBox) e.getSource()).getName();
if(((JCheckBox) e.getSource()).isSelected())
{
if(selsalad<2)//selsalad is 0 in the bigining
{
selectedsalad[selsalad]=((JCheckBox) e.getSource()).getName();
selsalad=selsalad+1;
}
else
{
((JCheckBox) e.getSource()).setSelected(false);
showMessageDialog(null, "you cant have more than 2 salads");
}
}
if(!((JCheckBox) e.getSource()).isSelected())
{
if(selectedsalad[0].equals(s)|| selectedsalad[1].equals(s) )
{
if(selsalad<2)
{
selectedsalad[selsalad]="";
}
selsalad=selsalad-1;
showMessageDialog(null, selsalad);
}
} }
}
});
x++;
}
}
} catch (Exception e) {
showMessageDialog(null, e);
}
}
this is how i filled the check boxex
for(Component c : jPanel7.getComponents())
{
if(c instanceof JCheckBox)
{
JCheckBox temp=(JCheckBox) c;
if(temp.getName().equals(s1)){
temp.setSelected(true);
}
if(temp.getName().equals(s2)){
temp.setSelected(true);

The number of check boxes selected are checked on the actionListener of each of these CheckBox. Action listeners aren't called when you are call setSelected(true) on the choice boxes.
You need to call the doClick(), if you want to call the action listeners.
JCheckBox temp=(JCheckBox) c;
if(temp.getName().equals("a1")){
temp.doClick();
}
if(temp.getName().equals("a2")){
temp.doClick();
}
Further, since both the if statements are doing the same stuff, you can just combine them.
if(temp.getName().equals("a1") || temp.getName().equals("a2")){
temp.doClick();
}

Your problem is that you're not updating the selsalad when you programmatically select a JCheckBox. Better perhaps is to get rid of the selsalad variable completely, and instead within the ActionListener iterate through an ArrayList<JCheckBox> and count exactly how many have been selected. Or make your array of JCheckBox a field, improve its name and iterate through that.
For example:
import java.awt.Component;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;
import java.util.List;
import javax.swing.*;

How To Work Menu Items For All Opened Documents in Java Swing

I Want To work All Menu Items Functionality for All Opened Documents.In My Application It's working for Recently Opened Document only.For Example: I Open Two Files/Documents(say Document1 and Document2).My Application is work for Document2(Recent) only.If I Go with Document1 and try to Apply the Menu Items Functionality,It's not working for that.Because it is older one.In My Application I Add two Menu Items.One Open-->To open a file and another is ViewSpace-->for check the whether the functionality is working for all opened Documents or not.Please Check My Application and Help me.Thank You.

That is because your "tx" variable always references the most recently created JTextArea.
For your menu items you should be using an Action and you would create your Action by extending TextAction. The TextAction has a method that allows you to access the text component that last had focus. Then you do you processing on this component:

As already explained by camickr, your "tx" field always references the most recently created text area. Also, when you switch tabs, you want to make sure that the selected text area displays according to the current "view spaces" setting.
I think both problems can be fixed by making the following changes:
adding a list of text areas to keep track of them;
add a change listener to the tabbedPane component to handle tab switches;
add new text areas to this list as they are created;
modify the viewSpaceActionPerformed method to determine the selected tab and rename it to setDocumentContents.
In code:
// Change 1 (before the constructor).
private final List<JTextArea> textAreas = new ArrayList<>();
// Change 2 (after assigning the tabbedPane field in the constructor).
tabbedPane.addChangeListener(new ChangeListener() {
#Override
public void stateChanged(final ChangeEvent changeEvent) {
setDocumentContents();
}
});
// Change 3 (after creating a text area in the openActionPerformed method).
textAreas.add(tx);
// Change 4 (replacing the viewSpaceActionPerformed method).
private void setDocumentContents() {
final JTextArea textArea = textAreas.get(tabbedPane.getSelectedIndex());
String previous = textArea.getText();
if (viewSpace.isSelected()) {
previous = previous.replaceAll(" ", ".");
} else {
previous = previous.replaceAll("\\.", " ");
}
textArea.setText(previous);
textArea.setCaretPosition(0);
}

How To Write Close All Action For All Documents using Swing

I want to write close all action for all created documents. My application has Create and CloseAll menu items. When I create a single document and write some code on that then I click on CloseAll, it asks conformation dialog box "Whether do you want to save or not".
This case is working fine for me. But when I create multiple documents (more than five) and some documents are empty, some documents have text. Then I click on CloseAll menu item, it should ask conformation dialog box for all documents that have text. But my code is not working in this case. How can I achieve this?
My Working Code:
public class CloseAllAction extends javax.swing.JFrame implements ChangeListener {
JTextArea textArea;
JScrollPane scrollpane;
int tabCount=0,doc_count=0;
int i=0;
CloseButtonTabbedPane tabbedPane;
HashSet<String> docSet=new HashSet<>();
boolean update =false;
ArrayList<String> InternalClosing;
private final List<JTextArea> textAreas = new ArrayList<>();
private final List<JScrollPane> scrollPanes = new ArrayList<>();
public CloseAllAction() {
initComponents();
tabbedPane=new CloseButtonTabbedPane();
InternalClosing=new ArrayList<>();
