Re: cannot resolve symbol

I am importing the proper packages...even when I copy a file directly off a web page or from a book...one that has been proven to work...such as this one below..each time I try to create a class using Javac I get "cannot resolve symbol" for JFrame or setContentPane, and setSize.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class Alphabet extends JFrame {
JButton a = new JButton("Alibi");
JButton b = new JButton("Burglar");
JButton c = new JButton("Corpse");
JButton d = new JButton("Deadbeat");
JButton e = new JButton("Evidence");
JButton f = new JButton("Fugitive");
Alphabet() {
super("Alphabet");
setSize(360, 120);
JPanel pane = new JPanel();
FlowLayout lm = new FlowLayout(FlowLayout.LEFT);
pane.setLayout(lm);
pane.add(a);
pane.add(b);
pane.add(c);
pane.add(d);
pane.add(e);
pane.add(f);
setContentPane(pane);
}
public static void main(String[] arguments) {
JFrame frame = new Alphabet();
ExitWindow exit = new ExitWindow();
frame.addWindowListener(exit);
frame.show();
}
}
class ExitWindow extends WindowAdapter {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
}
