How to access the JTextfield on one panel from the button on the other pane

Question

Hi to all!
I m having very simple problem about getText() and setText(). I am developing the user interface for an application. I got the JTextField on one panel and one button on other panel. When I try to do getText() and SetText() operation on the JTextField which is placed on a JPanel with the help of JButton click event Which is placed on other panel. The JTextField doesn't response. My program is not showing any compilation as well as runtime error. So how can i solve this problem?
Note: Duke dollar for rigth answer.
Thanks! in advance!

I've looked at the other post and was wondering what happened to all of those It is working briliantly...
In any event, I've taken the original code and clean it up my way as shown below:
import java.awt.event.*;
public class MainClass {
   public static void main(String[] args) {
      MajorFrame majorFrame = new MajorFrame();
      majorFrame.setSize(550,550);
      majorFrame.show();
      majorFrame.addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent e) {
            System.exit(0);
   }  //method ends
}  //class endss
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import javax.swing.event.*;
public class MajorFrame extends JFrame implements ActionListener {
   Container contentPane = getContentPane();
   Panel1 panel1 = new Panel1();
   JButton buttonMajorFrame = new JButton("Button MajorFrame");
   public MajorFrame() {
      contentPane.setLayout(null);
      contentPane.setSize(550,550);
      panel1.setBounds(5,5,400,250);
      contentPane.add(panel1);
      buttonMajorFrame.setBounds(5,350,150,20);
      buttonMajorFrame.addActionListener(this);
      contentPane.add(buttonMajorFrame);
   } //constructor ends
   public void actionPerformed(ActionEvent ev) {
      if (ev.getSource() == buttonMajorFrame) panel1.panel11.textField11.setText("majorFrame working");
   } //methode ends
} //class endss
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class Panel1 extends JPanel {
   Panel11 panel11;
   Panel12 panel12;
   public Panel1() {
      panel11 = new Panel11();
      panel12 = new Panel12(panel11);
      setLayout(null);
      panel11.setBounds(5,5,200,50);
      add(panel11);
      panel12.setBounds(5,65,200,50);
      add(panel12);
   //end constructor
}//end classs
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import javax.swing.event.*;
public class Panel11 extends JPanel implements ActionListener {
   public JTextField textField11;
   JButton button11;
   public Panel11() {
      setLayout(null);
      textField11 = new JTextField();
      button11 = new JButton("Button 11");
      textField11.setBounds(5,5,120,20);
      add(textField11);
      button11.setBounds(5,25,120,20);
      button11.addActionListener(this);
      add(button11);
   } //constructor ends
   public void actionPerformed(ActionEvent ev) {
      if (ev.getSource() == button11) textField11.setText("Text11 working");
   } //method ends
} //class endss
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import javax.swing.event.*;
public class Panel12 extends JPanel implements ActionListener {
   JButton button12 = new JButton("Button 12");
   public Panel11 panel11;
   public Panel12(Panel11 panel11) {
      this.panel11=panel11;
      setLayout(null);
      button12.setBounds(5,5,120,20);
      button12.addActionListener(this);
      add(button12);
   }//constructor ends
   public void actionPerformed(ActionEvent ev) {
      if (ev.getSource() == button12) panel11.textField11.setText("Text12 working");
   }//method ends
}//class endssI think this is what you're looking for and hope it saves your rear end...hehehe!
