What is event listener model in Java?
The EventListener interface is the primary method for handling events. Users implement the EventListener interface and register their listener on an EventTarget using the AddEventListener method. The users should also remove their EventListener from its EventTarget after they have completed using the listener.
What is the delegation event model in Java?
The Delegation Event Model is used to handle events in Java applications. It provides a way of notifying components of events that have occurred, such as mouse clicks or key presses. By using the Delegation Event Model, Java developers can create applications that are more flexible and easier to maintain.
In the Delegation model, a source generates an event and forwards it to one or more listeners, where the listener waits until they receive an event. Once the listener gets the event, it is processed by the listener, and then they return it. The UI elements can delegate an event's processing to a separate function.
