ActionListener

[Kid Programmer]

I have an action listener question. What goes in the parameters when adding an action listener to a button. Here is my code:

package NumberAverager;

import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JTextField;
import javax.swing.JLabel;
import java.awt.Container;
import java.awt.FlowLayout;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;

class NumberAverager
{
	public static void main(String[] args)
	{
		//create and set the title for a new frame
		JFrame frame = new JFrame();
		frame.setTitle("Number Averager");
		
		//create a container
		Container contentPane = frame.getContentPane();
		
		//create a layout and apply it to the contentPane
		FlowLayout layout = new FlowLayout();
		frame.setLayout(layout);
		
		//create components
		JTextField num1 = new JTextField("Number 1");
		JTextField num2 = new JTextField("Number 2");
		
		JButton calculate_average = new JButton("Calculate average");
		
		JLabel average = new JLabel("Average");
		
		//add the components
		contentPane.add(num1);
		contentPane.add(num2);
		
		contentPane.add(calculate_average);
		
		contentPane.add(average);
		
		//create action listeners
		calculate_average.addActionListener(WHATGOESHERE?);
		
		//frame settings
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.pack();
		frame.setVisible(true);

	}
}
