Introduction of Swing GUI

  • Swing GUI provides richer components and improved functionality over AWT, while JavaFX is a more modern and flexible GUI framework. JavaFX is another popular GUI framework for Java, introduced in Java SE 8, which provides enhanced capabilities and a more contemporary approach to GUI development. However, Swing is still widely used and supported in Java.

Definition of Swing GUI

  • Swing is a GUI toolkit provided by Java that extends the functionality of AWT, i.e., Swing is an extension of the original AWT

Characteristics of Swing GUI

  • Swing provides a platform-independent way to create graphical user interfaces in Java applications.
  • Swing components are lightweight and provide more customizable options compared to AWT.
  • Swing is a GUI (Graphical User Interface) framework in Java that provides a rich set of components and tools for creating interactive and visually appealing desktop applications.
  • Swing is built on top of AWT (Abstract Window Toolkit) and provides a more powerful and flexible set of GUI components compared to AWT.
  • Swing provides many components, including text fields, checkboxes, radio buttons, combo boxes, menus, and more.
  • Swing also offers more advanced features like dialog boxes, tables, and customized rendering.
  • Swing provides a wide range of components including buttons, labels, text fields, checkboxes, radio buttons, lists, tables, scroll panes, menus, and more. It also supports various layout managers (FlowLayout, BorderLayout, GridLayout, GridBagLayout etc.) to control the positioning and arrangement of components within containers. In other words, Swing provides a wide range of components such as JTextField, JTextArea, JCheckBox, JRadioButton, JComboBox, JList, JTable, and more.
  • Swing also provides the ability to customize the look and feel of our application.
  • Swing is widely used for desktop application development in Java, providing a powerful and flexible GUI framework.
  • Swing also allows us to handle user events using event listeners and supports the Model-View-Controller (MVC) architectural pattern for building scalable and maintainable GUI applications.
  • To create a GUI using Swing, we typically use Swing classes such as JFrame, JPanel, JButton, JLabel, and so on. Thus, to create a GUI using Swing, we typically follow these steps:-
    • Import the necessary Swing classes:
import javax.swing.*; import java.awt.*;
    • Create a JFrame object, which represents the main window of our application:
JFrame frame = new JFrame("Swing GUI Example");
    • Set the layout manager for the frame. Layout managers are used to arranging components within containers:
frame.setLayout(new FlowLayout());
    • Create and configure the Swing components we need, such as buttons, labels, text fields, etc.:
JLabel label = new JLabel("Hello, World!");
JButton button = new JButton("Click Me!");
    • Add the components to the frame:
frame.add(label); frame.add(button);
    • Set up event listeners to handle user actions:
button.addActionListener(e -> {
// Code to be executed when the button is clicked
System.out.println("Button clicked!"); });
    • Set the size and behavior of the frame:
frame.setSize(300, 200);
