What is wrong with the code II?

Question

The code below did not display "test" as expected. Why and how
to fix it? Thanks.
import java.awt.*;
import javax.swing.*;
public class component extends JFrame
public component()
setTitle("add component test");
Container c = getContentPane();
ComboBoxTest cc = new ComboBoxTest("test");
c.add(cc);
setSize(200, 200);
setLocation(400, 300);
public static void main(String [] args)
component c = new component();
c.show();
class ComboBoxTest extends Component
public ComboBoxTest(String s)
a = new Label(s);
private Label a;
