In event-driven programming, which term refers to an object that handles events generated by user interaction?Question 9Answera.ActionListenerb.EventDispatcherc.EventListenerd.EventHandler

Demonstrate the use of Event Listener interfaces.

These events require the interaction of the end user.

Event-driven programming in Java GUI development involves:Question 2Answera.Writing sequential code that executes in a linear fashion.b.Handling user actions and events through event listeners.c.Using threads to handle user input.d.Ignoring user interactions and focusing only on the graphical components.
