An event listener is used in programming to listen for specific events, like user interactions or system events, and triggers a response or function when that event occurs. It allows for interactive elements in a program or website to respond dynamically to user actions, making the interface more engaging and user-friendly.

What is event listener?
An event listener is a function in programming that waits for a specific event to occur, such as a user interaction with a webpage or a change in a variable's value. When the event occurs, the listener executes a specified action or set of instructions. Event listeners are commonly used in web development to create interactive and dynamic websites.
What is registering action listener with a component?
Registering an action listener with a component involves attaching a listener object to the component so that it can be notified of certain events, such as a button click or a menu selection. This allows the listener to respond to the event by executing the defined actions or behaviors.
What is the difference betweena passive listener and an impatient listener?

When a listener moves towards a stationary source of pitch of sound increase explain?
As a listener moves towards a stationary source of sound, the frequency of the sound waves received by the listener increases. This increase in frequency leads to a higher pitch perceived by the listener. This phenomenon is known as the Doppler effect.

A component subclass that has executed enableEvents to enable processing of a certain kind of event cannot also use an adapter as a listener for the same kind of event?
The answer is false,Processing of a certain kind of event can use an adapter as a listener for the same kind of event.
What is the difference between an event and an event listener?
Events are things that happen. Event listeners listen to these events and then do something in response.
When two or more objects are added as listeners for the same event which listener is invoked first to handle the event?
First to arrive at the event.
What are two basic steps for event handling in java?
1.Implement the Listener interface and overrides its methods 2.Register the component with the Listener
What is registering action listener with a component?

What is a delegation event model in java?
Event model is based on the concept of an 'Event Source' and 'Event Listeners'. Any object that is interested in receiving messages (or events ) is called an Event Listener. Any object that generates these messages ( or events ) is called an Event Source Event Delegation Model is based on four concepts: The Event Classes The Event Listeners Explicit Event Enabling Adapters The modern approach to handling events is based on the delegation event model, which defines standard and consistent mechanisms to generate and process events. Its concept is quite simple: a source generates an event and sends it to one or more listeners. In this scheme, the listener simply waits until it receives an event. Once received, the listener processes the event and then returns. The advantage of this design is that the application logic that processes events is cleanly separated from the user interface logic that generates those events. A user interface element is able to "delegate" the processing of an event to a separate piece of code.
