unable to clear text box in Multi Screen JFrame GUI Application

[harsh rocking]

i am working with a Swing GUI project where I want to accept user input in a
text field
I have used singleton pattern which will create only one instance of object
due to this when i move from one scree to another the input of textfield
doesnt updated I have used setText method to clear the JTextField but it wont
works
I have attached the code here which consists of two files
Program one -- 1st screen

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import java.awt.event.*;
import javax.swing.JTextField;

public class Frame1 extends JFrame
{
    public static Frame1 frame1;
    public JButton button;
    public JTextField input;

    public static Frame1 getInstance()
    {
        if(frame1==null)
          frame1 = new Frame1();
        return frame1;
    }

    public JButton getJButton(String mytext)
    {
        JButton button = new JButton();
        button.setText(mytext);
        button.setBounds(450,450,150,50);
        return button;
    }

    public void myGUI()
    {
        JPanel panel = new JPanel();
        panel.setLayout(null);

        button = getJButton("1st Frame");
        addActionListener(button);
        input = new JTextField(10);
        input.setBounds(200,300,100,30);
        panel.add(input);           
        panel.add(button);
        add(panel);
        setUndecorated(true);
        setSize(1024, 768);
        setVisible(true);
        setDefaultCloseOperation(EXIT_ON_CLOSE);

    }
    public void addActionListener(Object obj)
    {
        try{
        JButton button1 = (JButton)obj;
        button.addActionListener(new ActionListener()        {
           
            public void actionPerformed(ActionEvent ae)
            {               
                String text = "";      
                input.insert("", 0);
                Frame2.getInstance().myGUI();
                Frame2.getInstance().repaint();
                dispose();
            }
        }
       
    );
    }
        catch(Exception e1)           
        {
        System.out.println("Exception==>    "+e1.toString());   
        }   
    }

    public static void main(String[] args)
    {
        Frame1.getInstance().myGUI();
        Frame1.getInstance().repaint();           
    }
}

program 2 - 2nd screen

import javax.swing.JFrame;
import javax.swing.JPanel;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import java.awt.event.*;
import javax.swing.JTextField;

public class Frame2 extends JFrame
{
    static Frame2 frame2;
    public JButton BackButton;   
    public JTextField input;
   
    public static Frame2 getInstance()
    {
        if(frame2==null)
            frame2 = new Frame2();
        return frame2;
    }
        public JButton getJButton(String mytext)
    {
        JButton button = new JButton();
        button.setText(mytext);
        button.setBounds(450,450,150,50);

        return button;
    }
    public void addActionListener(Object obj)
    {
        try{
       
        JButton BackButton1 = (JButton)obj;
        BackButton.addActionListener(new ActionListener()
        {
            public void actionPerformed(ActionEvent ae)
            {
                input.setText("");                           
                Frame1.getInstance().myGUI();
                Frame1.getInstance().repaint();   
                dispose();
               
            }
        }
       
        );
        }
        catch(Exception e2)
           
        {
            System.out.println("Exception==>    "+e2.toString());
        }
    }
   
    public void myGUI()
    {
       
        JPanel panel2 = new JPanel();
        panel2.setLayout(null);

        BackButton = getJButton("2nd Screen");
        addActionListener(BackButton);
        input = new JTextField(10);
        input.setBounds(200,300,100,30);
        panel2.add(input);
        panel2.add(BackButton);
        add(panel2);
        setUndecorated(true);
        setSize(1024, 768);
        setVisible(true);
        setDefaultCloseOperation(EXIT_ON_CLOSE);

    }
}

In this application the status of TextField input remain same means it shows
the earlier input in the textfield wnen I come to earlier or next screen.
what is the solution to clear the TextField input while moving from 1st
scrren to 2nd screen.

Welcome to JavaRanch,

Please UseCodeTags to make your code easier to read.

You are adding an action listener to the button inside one action listener.
So who calls the first action listener? If the action listener is never called, do you think the setText("") would ever be executed?

is the only thing the current crop of greenhorns know how to do well is to cross-post?
is it part of the training?

very frustrating, getting close to being a total waste of time trying to help these people

I am sorry I am new to all these forums I don't know about the multiple posting
I will follow the code of conducts here on Michael.
Please share your knowledge with me. I am working on this code on last few
days but I am unable to solve this. Please help me your time is very important for me.

I am also tried it but it wont work. I had worj on above code lot.
Please help me

Since you are not willing to answer even simple questions like "did you read my previous reply" I do not see how else to further help you.

Yes I have read your earlier post and go through the link you have posted their.

As you say setText("") is executing properly but it is unable to clear the TextField in the GUI
The above application is working properly and is response to the button action very well
the problem is that I have used singleton design pattern which create only one object
of the Class if I doesn't use singleton then it works properly but that is bad coding as it create new object
each time. So in singleton approach their is single object which is unable to update the state next time
when i call setText("") function to clear the textField
