Thread: Swing, JFrame simple questions!

Okay I am trying to make a small inventory system for educational purposes.
I have a password Jframe and when the password is typed correctly I want it to close the password frame and open up my second file (mainpage.java).
Here are the 2 codes!
First gui (Password frame):

import javax.swing.; //access the jframe import java.awt.event.; import java.awt.*;
public class FirstGui {
private static String password = "password";
public static void main(String[] args) {
// TODO Auto-generated method stub
JFrame theGUI = new JFrame();

theGUI.setTitle("Thrift Store Inventory System");// Assigned the Gui title

theGUI.setSize(350, 100);

theGUI.setDefaultCloseOperation(JFrame.EXIT_ON_CLO SE); //Assigned closed operation

JLabel label = new JLabel("Enter Password");
JPanel panel = new JPanel();
theGUI.add(panel);

JPasswordField password = new JPasswordField(10);
password.setEchoChar('*');
password.addActionListener(new AL());
panel.add(label, BorderLayout.WEST);
panel.add(password, BorderLayout.EAST);

theGUI.setVisible(true);

}

static class AL implements ActionListener {


public void actionPerformed(ActionEvent e) {
JPasswordField input = (JPasswordField) e.getSource();
char[] passy = input.getPassword();
String p = new String(passy);

if (p.equals(password)){
************ CODE SHOULD BE HERE?!?! **************

}
else {
JOptionPane.showMessageDialog(null, "Incorrect");
}

}
}
}

Heres the second file!

import java.awt.event.ActionEvent; import java.awt.event.ActionListener;
import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; import javax.swing.JOptionPane;
public class MainPage {
public static void main(String[] args) {

JFrame theGUI = new JFrame();

theGUI.setTitle("Thrift Store Inventory System");// Assigned the Gui title

theGUI.setSize(350, 100);

theGUI.setDefaultCloseOperation(JFrame.EXIT_ON_CLO SE); //Assigned closed

JMenuBar menubar = new JMenuBar();
theGUI.setJMenuBar(menubar);

JMenu file = new JMenu("File");
menubar.add(file);
JMenuItem exit = new JMenuItem("Exit");
file.add(exit);

JMenu help = new JMenu("Help");
menubar.add(help);
JMenuItem about = new JMenuItem("About");
help.add(about);
about.addActionListener(new aboutaction());

theGUI.setVisible(true);

class exitaction implements ActionListener {
public void actionPerformed (ActionEvent e) {
System.exit(0);
}

}
exit.addActionListener(new exitaction());

}

static class aboutaction implements ActionListener {
public void actionPerformed(ActionEvent e){
JOptionPane.showMessageDialog(null, "Created by Jks");
}

}
}

So what do you seem to be stuck on?

In the IF statement that checks if password is correct I want to close the current (Password window) and open up the second window (Mainpage.java)

So what do you seem to be stuck on?

We are playing this game backwards.
You are supposed to ask the questions and read the replies.
I'll save the rest of my questions for answers that are of interest to me.
