error: expected with addActionListener class










0















I'm having issues with this simple block of Java code. I'm supposed to write an application that displays a JFrame containing the opening sentence from A Christmas Carol. When the user clicks the button, it will display the title of the book that contains the quote in the available JLabel using the setText() method.



However, when I compile, I'm getting errors that an is expected for my line to add the ActionListener for the button. I feel like I'm missing something simple, but I can't place it. Below is my source code. Thanks for any help.



import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class JBookQuote extends JFrame
FlowLayout flow = new FlowLayout();
JLabel msg1 = new JLabel("To begin with,");
JLabel msg2 = new JLabel("Marley was dead.");
JButton button = new JButton("Click for source");
JLabel msg3 = new JLabel();
String title = "** A Christmas Carol **";
public JBookQuote()
add(msg1);
add(msg2);
add(button);
add(msg3);
setLayout(flow);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);


button.addActionListener(new ActionListener()
@Override
public void actionPerformed(ActionEvent e)

msg3.setText(title);

);
public static void main(String args)
JBookQuote aFrame = new JBookQuote();
aFrame.setSize(300, 150);
aFrame.setVisible(true);

your code to add the actionlistener to your button isn't in a function, I think you want it in your constructor.
