Adding a action listener to button
This document shows how to add an action listener to a button in Java. It imports necessary classes like JButton and ActionListener. It creates a JFrame with a button that displays a message dialog when clicked. The button is given an action listener that calls showMessageDialog when the button's actionPerformed method is triggered. The button is added to a panel and frame for display.
