AWT vs Swing: Java GUI Toolkit Explained

AWT (Abstract Window Toolkit) is an early Java GUI toolkit, initially released in 1995. It was the first GUI toolkit provided in Java SE. AWT offers basic GUI components like buttons, text fields, and labels. AWT relies on native operating system GUI components, resulting in its appearance and feel being dependent on the OS. This means the same AWT code may have a different look and feel across various operating systems.

Swing is a Java GUI toolkit released after AWT and is part of Java SE. Swing provides a set of advanced GUI components, such as JButton, JTextField, JLabel, etc. Swing components are purely Java-based, ensuring a consistent appearance and feel regardless of the operating system. Swing also offers more customization options to tailor the appearance and feel of components.

Therefore, the main difference between AWT and Swing is that AWT relies on native operating system GUI components, while Swing is purely Java-based and provides more customization options.
