Unable to clear text Field in Multi Screen JFrame GUI Application

Question

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;
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.
