Java swing: Three ways to implement ActionListener listener Swing is an indispensable window tool group in Java and a powerful tool for users to build graphical user interface (GUI) programs. Java Swing components automatically generate events to respond to user behavior.ActionListener in Java is a class that is responsible for handling all action events such as when the user clicks on a component. Mostly, action listeners are used for JButtons. An ActionListener can be used by the implements keyword to the class definition. It can also be used separately from the class by creating a new class that implements it.The code below shows you how to add an ActionListener to a JComboBox component. In the snippet we add a listener by calling the addActionListener() method and give an instance of ActionListener listener as an anonymous class (a class without a specified name) as the parameter.. The ActionListener interface contract said that we must implement the actionPerformed(ActionEvent e) method.Java Swing is a GUI (graphical user Interface) widget toolkit for Java. Java Swing is a part of Oracle's Java foundation classes . Java Swing is an API for providing graphical user interface elements to Java Programs.Swing was created to provide more powerful and flexible components than Java AWT (Abstract Window Toolkit).Using Java Lambda expression for Listener Code in Swing Because the ActionListener interface defines only one method actionPerformed (), it is a functional interface which means there's a place to use Lambda expressions to replace the boilerplate code. The above example can be re-written using Lambda expressions as follows: 1The Java ActionListener is notified whenever you click on the button or menu item. It is notified against ActionEvent.

This article will focus on creation of form having components such as TextBox, TextArea, Label, RadioButton, Button, CheckBox etc. and also how to handle events if generated by a particular component. 2.1. Setup. Prerequisite: The listener interface for receiving action events. The class that is interested in processing an action event implements this interface, and the object created with that class is registered with a component, using the component's addActionListener method. When the action event occurs, that object's actionPerformed method is invoked. Since: 1.1The listener interface for receiving action events.

A commonly used component that generates a ActionEvent is a JButton, which is simply a button that produces an event when pressed. This article serves to explain three different ways an ActionListener can be added to a component. Component as ActionListenerIn swing, we can create a push button using the JButton class. We can watch for the click event on it using the ActionListener. When the user clicks the button, it produces the ActionEvent, and the event will go to the registered Listener. 2.
