Hi Apoorva,
Here I am giving you working code. This cocmpletely solves your problem.
import java.awt.Rectangle;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JPasswordField;
import javax.swing.SwingUtilities;
public class test extends JFrame {
     private static final long serialVersionUID = 1L;
     private JPanel jContentPane = null;
     private JButton jButton = null;
     private JPasswordField tPasswordField;
      * This method initializes jButton     
      * @return javax.swing.JButton     
     private JButton getJButton() {
          if (jButton == null) {
               jButton = new JButton();
               jButton.setBounds(new Rectangle(85, 121, 104, 27));
               jButton.setText("Click");
               jButton.addActionListener(new java.awt.event.ActionListener() {
                    public void actionPerformed(java.awt.event.ActionEvent e) {
                         System.out.println("actionPerformed()"); // TODO Auto-generated Event stub actionPerformed()
//                         JPasswordField tPasswordField = new JPasswordField(
                         tPasswordField = new JPasswordField(10);
                         tPasswordField.setEchoChar('*');
                         SwingUtilities.invokeLater(new Runnable()
                            public void run()
                                   tPasswordField.requestFocus();
                         int ret=JOptionPane.showConfirmDialog(test.this,
                                   tPasswordField,
                                   "Enter server password",
                                   JOptionPane.OK_OPTION);
          return jButton;
      * @param args
     public static void main(String[] args) {
          // TODO Auto-generated method stub
          SwingUtilities.invokeLater(new Runnable() {
               public void run() {
                    test thisClass = new test();
                    thisClass.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                    thisClass.setVisible(true);
      * This is the default constructor
     public test() {
          super();
          initialize();
      * This method initializes this
      * @return void
     private void initialize() {
          this.setSize(300, 200);
          this.setContentPane(getJContentPane());
          this.setTitle("JFrame");
      * This method initializes jContentPane
      * @return javax.swing.JPanel
     private JPanel getJContentPane() {
          if (jContentPane == null) {
               jContentPane = new JPanel();
               jContentPane.setLayout(null);
               jContentPane.add(getJButton(), null);
          return jContentPane;
}Now u can mark this as fixed and assign duke stars.. :-)
