//like this?
import javax.swing.*;
import java.awt.*;
import java.net.*;
import java.awt.image.*;
import java.awt.event.*;
public class test6 extends JPanel {
public test6() {
setPreferredSize(new Dimension(300, 300));
JButton b = new JButton("add");
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
JButton a = new JButton("ASDFASFAFAFA");
add(a);
updateUI();
}
});
add(b);
}
// main function
public static void main(String[] args) {
JFrame f = new JFrame("asdf");
test6 b = new test6();
f.getContentPane().add(b);
f.pack();
f.setVisible(true);
}
}
 
It is sorta covered in the JavaRanch Style Guide.
