What does ActionEvent e mean?

I am learning Java and would really like to have a deeper understanding of what the ActionEvent e perameter means and stands for. When I code I don\'t just want to spit out

This should help you: http://docs.oracle.com/javase/tutorial/uiswing/events/actionlistener.html

Basically,ButtonListener is your ActionListener Implementation. You will use it like

someButton1.addActionListener(new ButtonListener());
someButton2.addActionListener(new ButtonListener());

It will listen for any action events on the buttons 'someButton1' and 'someButton2'.But we might want to handle clicks on both buttons in a different way. Thats when ActionEvent is of use.

Inside method,we can do this by following

@Override
public void actionPerformed(ActionEvent e){
    if(e.getActionCommand().equals("Button 1")){
        //Process Button 1 action event here 
    }
    else if(e.getActionCommand().equals("Button 2")){
        //Process Button 2 action event here 
    }

}
