The classes that represent events are at the core of Java's event handling mechanism Thus a discussion of event handling must begin with the event classes
What is event handlers in OOP?
There are five main tasks in creating your own event type:
1Create an event listener. 2) Create a listener adapter. 3) Create an event class. 4) Modify the component. 5) Managing multiple listeners.
What are the three main components of event handling?
In programming, an event handler is a callback routine that operates asynchronously once an event takes place. It dictates the action that follows the event. The programmer writes a code for this action to take place. An event is an action that takes place when a user interacts with a program.
How to create an event in Java?
An event listener in Java is designed to process some kind of event — it "listens" for an event, such as a user's mouse click or a key press, and then it responds accordingly. An event listener must be connected to an event object that defines the event.
What is Event Handling? Event Handling is the mechanism that controls the event and decides what should happen if an event occurs. This mechanism have the code which is known as event handler that is executed when an event occurs. Java Uses the Delegation Event Model to handle the events.
