Java Applet program to create different screen and link them together

Hi,

I'm very new to java, and currently learning some of the basics.

What i need help on is how to program in java so that i can change from one window to another. Not really sure how to word this but here goes:

For example, when i start the java applet, a login screen (window1) will appear, when a user enters username and password, when the user is verified, it "switches" to a different window (window2) to access the data.

Any help much appreciated.

Thanks in advance,

Hello channi3 and welcome to the forums.

Take a look at this code example and compile it.

There is a main JFrame with a button on it. When this button is clicked, JFrame1 closes and opens JFrame2.

Its just a matter of invoking the run method for each form when an action is performed and setting the visibility of the previous form to false.

Code :

---

import javax.swing.*;   
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
 
public class Channi3 {
 
    public static JFrame frame1 = new JFrame("Java Frame1");
    public static JFrame frame2 = new JFrame("Java Frame2");
 
    //Form1
    private static void createAndShowGUI1()  {
 
        frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
        JButton button = new JButton("HI! IM JFRAME1 - CLICK ME TO OPEN FRAME 2");
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e)
            {
                [B]frame1.setVisible(false);[/B]
                System.out.println("Opening JFrame 2");
                javax.swing.SwingUtilities.invokeLater(new Runnable() {
                    public void run() {
                        [B]createAndShowGUI2();[/B]
 
                    }
                });
            }
 
        });      
 
        frame1.getContentPane().add(button);
        frame1.pack();
        frame1.setVisible(true);
    }
 
 
    //Form2
    private static void createAndShowGUI2()  {
 
        frame2.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
        JButton button = new JButton("HI! IM JFRAME2 - CLICK ME TO OPEN FRAME 1");
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e)
            {
                [B]frame2.setVisible(false);[/B]
                System.out.println("Opening JFrame 1");
                javax.swing.SwingUtilities.invokeLater(new Runnable() {
                    public void run() {
                        [B]createAndShowGUI1();[/B]
 
                    }
                });
            }
 
        });      
 
        frame2.getContentPane().add(button);
        frame2.pack();
        frame2.setVisible(true);
    }
 
 
 
    public static void main(String[] args) {
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI1();
            }
        });
    }
}
