Trouble with login page to program page

[montalbano80]

I am having some trouble with my Java program. I completed a PoolVolume class project and am trying to add a login and password page before the PoolVolume class starts. I completed the login and password script but can not get the login page to access the next class page. I ran both codes and they work by themselves but will not work together. Can anyone take a look at it and let me know where I am going wrong and how to fix. I am just stumped!! Thank you!!

Login class and PoolVolume class are part of LoginForm Project

Login:

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

class Login extends JFrame implements ActionListener
{
JButton SUBMIT;
JPanel panel;
JLabel label1,label2;
final JTextField text1,text2;
Login()
{
label1 = new JLabel();
label1.setText("Username:");
text1 = new JTextField(15);

label2 = new JLabel();
label2.setText("Password:");
text2 = new JPasswordField(15);

SUBMIT=new JButton("SUBMIT");

panel=new JPanel(new GridLayout(3,1));
panel.add(label1);
panel.add(text1);
panel.add(label2);
panel.add(text2);
panel.add(SUBMIT);
add(panel,BorderLayout.CENTER);
SUBMIT.addActionListener(this);
setTitle("LOGIN FORM");
}
public void actionPerformed(ActionEvent ae) {
String value1=text1.getText();
String value2=text2.getText();
if (value1.equals("mike") && value2.equals("3180")) {
PoolVolume page=new PoolVolume();
}
else{
System.out.println("enter the valid username and password");
JOptionPane.showMessageDialog(this,"Incorrect login or password","Error",JOptionPane.ERROR_MESSAGE);
}
}
}
class LoginForm{
	public static void main(String arg[]) {
	try {
	Login frame=new Login();
	frame.setSize(300,100);
	frame.setVisible(true);
	}
	catch(Exception e)
	{JOptionPane.showMessageDialog(null, e.getMessage());}
	}
}

please, just as advice,

1/ replace JPanel(s) instead of creating plenty of JFrame without DefaultCloseOperation
2/ JFrame + JDialod (be sure that with dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);)
3/ don't extends TopLayOutContainer (JFrame, JDialog, JOptionPane or Window), maybe one time you need/want to create a plain vanilla constuctor from someClass back to mainClass
4/ its very, really strange catch focus between some JFrames (if contains lots of JPanels)
5/ back to your question I think that addOn page.setVisible(true); will solve your problem

6/ and learn how to use LayourManarer, just for resize issue PreferredSize

f.e.

frame.setPreferredSize(525, 350);
frame.pack();
frame.setVisible(true);

7/ your login (JFrame) should be JDialog

If I was to addOn page.setVisible(true); which part would I add it to, the login code or the pool volume code and where. Sorry, but I actually have just been doing Java for only the past 5 weeks. Thank you for the other tips, I appriciate it.

if (value1.equals("mike") && value2.equals("3180")) {
    PoolVolume page=new PoolVolume();
    page.setVisible(true);
}else.......
