JFrame Eclipse 'add' command error

While trying to add a button with "click me" written on it I get the following error message:

Exception in thread "main" java.lang.Error: Unresolved compilation problem: Cannot make a static reference to the non-static method add(Component) from the type Container

import javax.swing.JButton;
import javax.swing.JFrame;
public class FirstFrame extends JFrame {

    public static void main(String[] args) {
        JFrame frame = new JFrame("My little frame");
        JButton button = new JButton("Click Me");
        add(button);
        frame.setSize(300,200);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
}

Any help to resolve this error would be much appreciated!

The add() method is an instance method, and can only be called on an instance of (in this case) frame.

try

frame.add(button);
