I am posting this question to gain clarity on the fundamental distinctions and practical applications of the Event versus EvenHandler.
Event Overview:- An event in the realm of computing refers to an action or incident that is detected by a program and can be processed accordingly. These events are typically managed synchronously within the program's flow, with specific locations dedicated to handling them.
Understanding EventHandlers:-
An EventHandler is essentially a function or method containing code that responds to a particular event. It serves as a software routine that interprets actions such as keyboard inputs and mouse movements. In websites, EventHandlers play a vital role in making content dynamic, often scripted using JavaScript.
A simple illustration involves clicking on the login button on Facebook. This action triggers the corresponding event handler, signaling the Facebook application that the user is attempting to log in.
It is not appropriate to equate the Handler and event.
The handlers are saved within a HandlerManager that oversees the distribution of all types of events (including those you generate yourself).
Furthermore,
Handlers receive an Event object containing all the details of the Event as their sole parameter i.e Event
Interpretations of events can vary based on the situation at hand. Generally, an event refers to an action or incident within a program; programs typically manage events through specific modules known as handlers.
For instance, in Java, pressing a button may trigger an event, leading the program to execute the code contained within the corresponding event handler.
