I have created two window frame in JAVA using awt and swing package. My Java code is like:

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

public class TopLevelWindow {

private static void createWindow() {
JFrame frame = new JFrame(“Simple GUI”);

//frame.setDefaultCloseOperation(JFrame.EXIT_ON_ CLOSE);
JLabel textLabel = new JLabel(“Hi Ans “,SwingConstants.CENTER);
textLabel.setPreferredSize(new Dimension(300, 100));
frame.getContentPane().add(textLabel, BorderLayout.CENTER);

//Display the window.
frame.setLocationRelativeTo(null);
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {

createWindow();
createWindow();
}

}

Now on executing my code I am getting two window like frame and switching between these two frames.
