1. Create a class that extends Applet and implements an interface.
class<name> extends Applets implements <interface>
Class Skey extends Applet implements MouseListener
There are different Interfaces for different events i.e.for keyboard->KeyListner, for Mouse->MouseListner/MouseMotionListner etc.
2. Initialize applet by init method.
init() { }
3. Add or Register the listener to source for receiving notification. Each type of event has its own listener.
4. Implement the method to receive and process these notifications.- add TypeListener(TypeListener);
- addMouseListener(this);
- public void method(eventclass obj){}
- public void mouseEntered(MouseEvent m){}
- public void mousePressed(MouseEvent m){}
- public void mouseClicked(MouseEvent m){}
- public void mouseExited(MouseEvent m){}
- public void mouseReleased(MouseEvent m){}
- Event Source: ex.Button, CheckBox
- EventListener Interface: MouseListener
- Event classes: Mouse Event
- Methods of EventListener Interface: mouseEntered(),mousePressed(),mouseReleased(),mouseExited(),mouseClicked()
