The different types of events related to listeners are:

ContextRefreshedEvent – This gets called when the context is refreshed or initialized.

RequestHandledEvent – This gets called when the web context is handling a request.

ContextClosedEvent – This gets called when the context gets closed.

public class EventHandlingExample1 {   
      
    // create variables for Frame, Label and Panel   
    private Frame frame;   
    private Label header;   
    private Label status;   
    private Panel panel;   
      
    // default constructor   
    public EventHandlingExample1(){   
        makeGUI();   
    }   
      
    // main() method start   
    public static void main(String[] args){   
          
        // create an instance of EventHandlingExample1   
        EventHandlingExample1  obj = new EventHandlingExample1();   
        obj.addButtonsAndLabel();   
    }   
      
    // create makeGUI() method to create a UI to perform user interaction   
    private void makeGUI(){   
          
        // initialize Frame   
        frame = new Frame("Event Handling Example");   
          
        // set frame size by using setSize() method   
        frame.setSize(400,400);   
          
        //set frame layout by using setLayout() method   
        frame.setLayout(new GridLayout(3, 1));   
          
        // add window listener to frame   
        frame.addWindowListener(new WindowAdapter() {   
            public void windowClosing(WindowEvent windowEvent){   
                System.exit(0);   
            }           
        });    
          
        // initialize header and set alignment to center   
        header = new Label();   
        header.setAlignment(Label.CENTER);   
          
        //initialize status and set its alignment and size   
        status = new Label();           
        status.setAlignment(Label.CENTER);   
        status.setSize(350,100);   
          
        // initialize panel   
        panel = new Panel();   
          
        // set flow layout to panel   
        panel.setLayout(new FlowLayout());   
          
        // add header, status and panel to frame   
        frame.add(header);   
        frame.add(panel);   
        frame.add(status);   
        frame.setVisible(true);     
    }
