How to display multiple jpassword field in pop up in swing java?

I have 2 JTextField and 2 JPasswordField component in my swing java which frame looks as below:
When ShowAllDetails button is clicked, all the entered details is displayed in JtextArea as shown below:
Below is the code for the same:
package popUpTest;
import java.awt.EventQueue;
import javax.swing.JFrame;
import javax.swing.JLabel;
import java.awt.Font;
import javax.swing.JPasswordField;
import javax.swing.JTextField;
import javax.swing.JButton;
import javax.swing.JTextArea;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
public class PopUpTest
{
private JFrame frame;
private JPasswordField passSourcePassword;
private JTextField txtSourceUserName;
private JTextField txtTargetUserName;
private JPasswordField passTargetPassword;
/**
* Launch the application.
*/
public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable()
{
public void run()
{
try
{
PopUpTest window = new PopUpTest();
window.frame.setVisible(true);
} catch (Exception e)
{
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public PopUpTest()
{
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize()
{
frame = new JFrame();
frame.setBounds(100, 100, 444, 403);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
JLabel lblSourceUserName = new JLabel("SourceUserName:");
lblSourceUserName.setFont(new Font("Tahoma", Font.BOLD, 16));
lblSourceUserName.setBounds(15, 62, 170, 20);
frame.getContentPane().add(lblSourceUserName);
passSourcePassword = new JPasswordField();
passSourcePassword.setBounds(15, 153, 147, 26);
frame.getContentPane().add(passSourcePassword);
JLabel lblSourcePassword = new JLabel("SourcePassword:");
lblSourcePassword.setFont(new Font("Tahoma", Font.BOLD, 16));
lblSourcePassword.setBounds(15, 132, 147, 20);
frame.getContentPane().add(lblSourcePassword);
txtSourceUserName = new JTextField();
txtSourceUserName.setBounds(16, 81, 146, 26);
frame.getContentPane().add(txtSourceUserName);
txtSourceUserName.setColumns(10);
JLabel lblTargetUserName = new JLabel("TargetUserName:");
lblTargetUserName.setFont(new Font("Tahoma", Font.BOLD, 16));
lblTargetUserName.setBounds(240, 62, 170, 20);
frame.getContentPane().add(lblTargetUserName);
txtTargetUserName = new JTextField();
txtTargetUserName.setColumns(10);
txtTargetUserName.setBounds(241, 81, 146, 26);
frame.getContentPane().add(txtTargetUserName);
JLabel lblTargetPassword = new JLabel("TargetPassword:");
lblTargetPassword.setFont(new Font("Tahoma", Font.BOLD, 16));
lblTargetPassword.setBounds(240, 132, 147, 20);
frame.getContentPane().add(lblTargetPassword);
passTargetPassword = new JPasswordField();
passTargetPassword.setBounds(240, 153, 147, 26);
frame.getContentPane().add(passTargetPassword);
JLabel lblEnterBelowDetails = new JLabel("Enter Below Details:");
lblEnterBelowDetails.setFont(new Font("Tahoma", Font.BOLD, 16));
lblEnterBelowDetails.setBounds(15, 26, 187, 20);
frame.getContentPane().add(lblEnterBelowDetails);
JTextArea textArea = new JTextArea();
textArea.setBounds(15, 252, 365, 85);
frame.getContentPane().add(textArea);
JButton btnShowAllDetails = new JButton("Show All Details:");
btnShowAllDetails.setBounds(15, 207, 226, 29);
frame.getContentPane().add(btnShowAllDetails);
btnShowAllDetails.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent arg0)
{
textArea.append(txtSourceUserName.getText() + "\n");
textArea.append(passSourcePassword.getText() + "\n");
textArea.append(txtTargetUserName.getText() + "\n");
textArea.append(passTargetPassword.getText() + "\n");
}
});
}
}
Now instead of diplaying these 4 components on loading the main frame instead, i want to diplay these 4 components in a Pop up Window on click of a button as below:
Also on clicking of Show All Details button should work as before.(i.e. it should populate JtextArea with the values entered in Pop Up)
How can I achieve this?
I have gone through other blogs as well however didn't find to show such multiple JPasswordField/JTextField in popup.Any guidance would be highly appreciated.

Just add the new components (JTextFields and JPasswordFields) within a button listener and call repaint() and revalidate() on the frame after that.
Here is a solution without proper layout:

By the way: try to read about layout managers as soon as possible, because absolute coordinates are a pain in the ass ;-)

add dynamic checkbox in java windowbuilder

I want to add a dynamic checkbox after selecting an item in combo box.
I am working on eclipse and design my frame on window builder.
final JComboBox<String> comboBox = new JComboBox<String>();
comboBox.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String typeName = comboBox.getSelectedItem().toString();
for (int i = 0; i < SqlQuery.getCoursesName(typeName).size(); i++) {
JCheckBox c = new JCheckBox(SqlQuery.getCoursesName(typeName).get(i));
c.setVisible(true);
coursePanel.add(c);
frame.repaint();
frame.validate();
System.out.println(c.getText());
}
}
});
comboBox.setBounds(208, 221, 91, 20);
frame.getContentPane().add(comboBox);

Hope you understand what I wrote. I want to show a list of coursesName after click on the comboBox.
Why the frame does'nt show the checkbox?
Thank you.

First and foremost. The comboBox.setBounds() is a very bad practice. Take some time and see Layout Managers. Also add 'swing' tag in your post since you are referring to Swing library.
The frame doesn't show the component because you repaint the wrong one. You add the checkbox in coursePanel, which means you have to repaint() & revalidate() coursePanel. So coursePanel.repaint() instead of frame.repaint() will help you.
Also checkBox.setVisible(true)is not required, since checkBox is visible by default.
Finally i have added the way of how i would do it.

combo.addActionListener(e -> {
//Its better to handle indices when there is not dynmic data to your combobox
int selectedIndex = combo.getSelectedIndex();
boolean isInPanel = checkBox.getParent() == p;
if (selectedIndex == 1 && !isInPanel) {
p.add(checkBox);
p.repaint(); //Repaint the proper panel that has this component.

label_6.setBounds(321, 245, 103, 14);

Another option is to create the checkbox as a field outside of the actionlistener (like i did) and set its bounds with window builder and use setVisible(false). Then on your listener, setVisible(true)

Program Terminates without running in eclipse

When I run this code ( having simple buttons and a LOGIN button with an action listener), it terminates without running and without showing screen.
I have tried System.exit(0); in main function to overcome this terminating issue but all in vain

You are not making your JFrame visible.
You can do either -
In your constructor, make it visible by adding the following line at the end -
setVisible(true);
Or in your main() function you can do -
HOme h = new HOme("HOme");
h.setVisible(true);

Answer to second part:
Import MouseListener, import java.awt.event.MouseListener;
Construct a MouseListener somewhere, include action of the button
Where you define btnLogin, add a line btnLogin.addMouseListener(<name of MouseListener>);
An example: http://www.java2s.com/Code/Java/Swing-JFC/ButtonActionSample.htm

Add something like setVisible(true); at the end of the HOme method.

Unable to make JDialog modal

Try making the dialog modal BEFORE you try and make it visible. You can't change the modal state once the dialog is made visible...
JDialog jd=new JDialog(loginpage.this,"User Registration");
jd.setModal(true);
jd.setLayout(null); // THIS IS A BAD IDEA //
jd.setLocationRelativeTo(null);
// This is somewhat pointless, you've set relative location, but know overridden it...
// You should also be relying on the layout manager and pack to determine the size...
jd.setBounds(400,300, 479, 329);
jd.setResizable(false);
setLocationRelativeTo(loginpage.this);
// Add you other components
jd.setVisible(true);

My JLabel text will not change

I am creating a final project for my computer programming course, and have run into a strange problem that I'm hoping someone could possibly help me with. I am attempting to make a blackjack program which will run between two computers, but am having trouble getting the text of my labels to change beyond what they are initially set to. To make this project I am using the eclipse compiler with the window builder addon.
The problem itself lies within the label "lblEnterTextHere", who's text will not change when i try to do so in the rungame method. The random System.out.print messages were to check if the code even reaches the point where this method is run, and it does. "Waiting for connection" is printed.
Note: I'm new to java, and this is merely a grade 12 course, so please explain your answer with clarity. It would help a lot. Also This isn't even a game yet, just the skeleton of what I'm trying to do.

You are blocking the EDT by placing ServerSocket functionality in that Thread. Place the functionality found in runGame in a SwingWorker and the UI will be free to update its components.
As you are don't require any return information you can use SwingWorker<Void, Void>
