    Default Need some help with this JFrame, or JDialog.

    well, bascially i am making a little log-in system for myself.
    i created a JFrame in which you create an account, when you click "ok" it pops up a window with the information you just filled in(password and username).
    then if you click "OK" on that window too, i want another JFrame to pop up that actually lets you log in with the information.

    how can i create 2 JFrames in a single class?

    this is the code:
    import javax.swing.JOptionPane;
    import java.awt.event.ActionListener;
    import java.awt.FlowLayout;
    import java.awt.event.ActionEvent;
    import javax.swing.JLabel;
    import javax.swing.JFrame;
    import javax.swing.JButton;
    import javax.swing.JTextField;
    import javax.swing.JPasswordField;
    import javax.swing.JPanel;
    public class LogIn extends JFrame{
     
    	private JTextField txt1;
    	private JTextField txt2;
    	private JPasswordField ps1;
    	private JPasswordField ps2;
    	private JPasswordField ps3;
    	private JLabel label1;
    	private JLabel label2;
    	private JLabel label3;
    	private JLabel label4;
    	private JLabel label5;
    	private JButton b1;
    	private JButton b2;
     
     
     
     
     
    public LogIn(){
    	super("Account");
    	setLayout (new FlowLayout());
    	label1 = new JLabel("Enter your username: ");
    	txt1 = new JTextField(10);
    	label2 = new JLabel("Enter your password: ");
    	ps1 = new JPasswordField(10);
    	label3 = new JLabel("Confirm your password: ");
    	ps2 = new JPasswordField(10);
    	b1 = new JButton("OK");
    	add(label1);
    	add(txt1);
    	add(label2);
    	add(ps1);
    	add(label3);
    	add(ps2);
    	add(b1);
     
     
    	thehandler handler = new thehandler();
    	b1.addActionListener(handler);
     
     
    }
    public class thehandler implements ActionListener{
    	public void actionPerformed(ActionEvent event){
    		if(txt1.getText().equals(ps1.getText())){
    		JOptionPane.showMessageDialog(null, "Password error, your username can't be the same as your password","Password Error!",JOptionPane.ERROR_MESSAGE);}
    		else if(ps1.getText().equals(ps2.getText())){
    		JOptionPane.showMessageDialog(null, "Account information: "+"\n"+"User: "+txt1.getText()+"\n"+"Password: "+ps1.getText(), "Account Information", JOptionPane.INFORMATION_MESSAGE);}
    		else{
    		JOptionPane.showMessageDialog(null, "Passwords did not match! Try again please!", "Password error!", JOptionPane.ERROR_MESSAGE);}
     
     
     
     
     
     
     
     
    	}
     
     
     
    }
    }

    how can i create 2 JFrames in a single class?
    Use the new statement:
    frame1 = new JFrame();
    frame2 = new JFrame(); //  Create second JFrame

    but im not sure how to actually create and set up a JFrame like that.

    i created my first JFrame like this:
    public LogIn(){
    	super("Account");
    	setLayout (new FlowLayout());
    	label1 = new JLabel("Enter your username: ");
    	txt1 = new JTextField(10);
    	label2 = new JLabel("Enter your password: ");
    	ps1 = new JPasswordField(10);
    	label3 = new JLabel("Confirm your password: ");
    	ps2 = new JPasswordField(10);
    	b1 = new JButton("OK");
    	add(label1);
    	add(txt1);
    	add(label2);
    	add(ps1);
    	add(label3);
    	add(ps2);
    	add(b1);

    i created my first JFrame like this
    That code does NOT create a JFrame. It looks like a constuctor for a class that was created somewhere else.
    A class instance/object is created by a new statement. Somewhere there is a call to new Login() that creates an instance of the Login class.

    The new statement is used to create an instance of a class.

    how to create a second JFrame in one class?
    I described that in post #2:
    JFrame frame2 = new JFrame(); //  Create second JFrame

    After the instance of JFrame is created, the code needs to add components to it and call the setVisible() method like what is done in the LogIn class's constructor code in post#3
