Calling an ActionEvent

I am in the process of learning and creating a custom JButton/Component. I have the most of what I need, except I do not know how to call actionPerformed on my ActionListners.

Code:

package myProjects;

import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Shape;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.geom.*;
import java.util.ArrayList;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.JFrame;

public class LukeButton extends JComponent{
    public static void main(String[] args){
        JFrame frame = new JFrame();
        frame.setTitle("Luke");
        frame.setSize(300, 300);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        LukeButton lb = new LukeButton();
        lb.addActionListener(e->{
            System.out.println("Success");
        });
        frame.add(lb);

        frame.setVisible(true);
    }

private final ArrayList<ActionListener> listeners = new ArrayList<ActionListener>();

public LukeButton(){

}
public void addActionListener(ActionListener e){
    listeners.add(e);
}
public void paintComponent(Graphics g){

    super.paintComponent(g);

    Graphics2D g2 = (Graphics2D)g;
    Shape rec = new Rectangle2D.Float(10, 10, 60, 80);

    g2.setColor(Color.BLACK);
    g2.setStroke(new BasicStroke(5));
    g2.draw(rec);
    g2.setColor(Color.BLUE);
    g2.fill(rec);
}
}

Does anyone one know how to call the "listeners" ArrayList once the button is clicked? Thanks for taking your time.

You need to loop over your list of ActionListeners and call their actionPerformed method, something like...

protected void fireActionPerformed() {
    if (!listeners.isEmpty()) {

        ActionEvent evt = new ActionEvent(this, ActionEvent.ACTION_PERFORMED, "LukeButton");
        for (ActionListener listener : listeners) {
            listener.actionPerformed(evt);
        }

    }
}

Now, you need to define the actions which might trigger a ActionEvent to occur, mouse click, key press etc and the call the fireActionPerformed method when they occur
