What is the role of Event Handling in Java GUI

Event Handling in Java GUI is a crucial aspect that allows programmers to respond to user actions such as mouse clicks, key presses, and other interactions within a graphical user interface (GUI). It enables the application to react dynamically to events, enhancing user experience and interactivity. With proper event handling, developers can create responsive and robust applications that provide immediate feedback to user actions.

In Java, event handling is primarily achieved through the use of listeners, which are interfaces that respond to specific events. When an event occurs, the corresponding listener method is triggered, allowing the application to execute a defined action.

import javax.swing.*; import java.awt.event.*; public class SimpleGuiExample { public static void main(String[] args) { JFrame frame = new JFrame("Event Handling Example"); JButton button = new JButton("Click Me"); button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { System.out.println("Button was clicked!"); } }); frame.getContentPane().add(button); frame.setSize(300, 200); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } }
