When I use JOptionPane's static methods to display some JTextFields,
initial focus is on one of the buttons, is it possible to set initial
focus to the JTextField?

example code:

import javax.swing.*;
import java.awt.*;

public class MyApp3 {

  public static JFrame frame;

  private static void createAndShowGUI() {
    JFrame frame = new JFrame("A test app");
    frame.setBounds(100,100,  300, 200);
    frame.setVisible(true);
    getPassword();
  }

  private static void getPassword() {
    JPanel panel = new JPanel();
    JTextField nameField = new JTextField(10);
    JPasswordField passwordField = new JPasswordField(10);
    panel.setLayout(new GridLayout(2,2, 5,10)); // rows,cols,vgap,hgap
    panel.add (new JLabel("Name", SwingConstants.RIGHT));
    panel.add (nameField);
    panel.add (new JLabel("Password", SwingConstants.RIGHT));
    panel.add (passwordField);
    int choice = JOptionPane.showConfirmDialog(
      MyApp3.frame,                  // parent
      panel,                         // "message"
      "Database Log-in",             // title
      JOptionPane.OK_CANCEL_OPTION,  // optiontype
      JOptionPane.PLAIN_MESSAGE      // messagetype: no icon
    );
    // do something with choice and credentials
  }
   
  public static void main(String[] args) {
    javax.swing.SwingUtilities.invokeLater(new Runnable() {
      public void run() { createAndShowGUI(); }
    });
  }

}
