Introduction to Swing in Java

Introduction to Swing

• Swing is a part of Java foundational classes used for creating graphical user interface (GUI) applications.
• Swing is built on top of the Abstract Window Toolkit (AWT) API and is written entirely in Java.
• Swing provides platform independence, meaning applications built with Swing can run on different operating systems without modifications.
• Swing contains lightweight components such as JButton, JTextField, JTextArea, JRadioButton, JCheckBox, JMenu, etc.

Java Foundational Classes (JFC)

• JFC is a set of GUI components that provide tools for designing desktop applications.

Hierarchy of Java Swing Classes

• Swing components can be organized into a hierarchical structure following the Component -> Container -> JContainer relationship.
• Frame, Dialog, Panel and Applet are all examples of Containers, which can contain other components.
• Swing includes various components like JLabel, JList, JTable, JComboBox, JSlider, JSpinner, JButton, JCheckBox, and JRadioButton.

Swing Features

• Swing uses a native approach to develop components for user interfaces, integrating with the underlying operating system to provide a consistent look and feel.
• Swing is a pluggable component architecture, which makes it compatible with various technologies and applications.
• Swing provides rich content features, including tabbed panels for organizing content and providing a tabbed interface for navigation.
