just stated learning Java. trying to create a java EmailFrame which will display a blank Submission Complete message.

but i keep getting error message when ever I try to compile the code.

error (Can not find symbol symbol method submit)

this is what my script looks like

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

public class EmailFrame extends JFrame
{
private InfoPanel infoPanel = new InfoPanel();

public EmailFrame()
{
super("Shared Listener Test");

setJMenuBar(createMenuBar());
getContentPane().add(infoPanel);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(190,150);
setLocation(300,300);
}

private JMenuBar createMenuBar()
{
JMenuBar menuBar = new JMenuBar();
JMenu menu;
JMenuItem item;



item = new JMenuItem("Exit");
item.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent evt)
{
System.exit(0);
}
});




return menuBar;
}

public static void main(String[] args)
{
JFrame f = new EmailFrame();
f.setVisible(true);
}
}

class InfoPanel extends JPanel
{
private JTextField firstname = new JTextField(10);
private JTextField lastname = new JTextField(10);
private JTextField email = new JTextField(15);

private JButton button = new JButton("Submit");

public InfoPanel()
{
button.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent evt)
{
submit();
}
});

setLayout(new GridLayout(4,2));

add(new JLabel("Firstname"));
add(firstname);
add(new JLabel("Lastname"));
add(lastname);
add(new JLabel("Email"));
add(email);
add(button);
}

public void clear()
{
firstname.setText("");
lastname.setText("");
email.setText("");
}
}

You're making a call to submit() whereas you have not defined a method called submit().

        button.addActionListener(new ActionListener()
            {
                public void actionPerformed(ActionEvent evt)
                {
                    <strong>submit();</strong>
                }
            });
