unable to clear text Field in Multi Screen JFrame GUI Application

[harshalforu]

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

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;

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.
