Difference between AWT and Swing

When it comes to Java user interface (UI) development, there are two main libraries that you will use: AWT and Swing. Both of these libraries provide a robust set of tools for creating UI components, but they differ in a few important ways. In this post, we’ll take a look at the key differences between AWT and Swing, so you can decide which one is right for your project.

What is AWT?

AWT stands for Abstract Window Toolkit. It is a set of tools that allows developers to create graphical user interface (GUI) components, such as buttons and scrollbars, in a platform-independent manner. The AWT was introduced as part of the Java programming language in 1995. Since then, it has been superseded by the Swing GUI framework. However, the AWT remains in use today for some legacy applications.

What is Swing?

Swing is a graphical user interface (GUI) toolkit for Java. It is part of the Java Foundation Classes (JFC), an extension of the Abstract Window Toolkit (AWT). Swing includes a rich set of widgets and provides a set of APIs for creating attractive and responsive user interfaces. Additionally, it provides a pluggable look and feels that allows applications to have the same appearance on multiple platforms. Swing also supports a wide range of input devices, such as keyboards, mice, and touchscreens. And, unlike AWT components, Swing components are not platform-dependent. As a result, they can be used on any platform that supports Java. Finally, Swing is fully customizable. Developers can create their own custom widgets or use ones that have been created by others.

Difference between AWT and Swing

There are two main types of graphical user interface (GUI) in Java: AWT and Swing. AWT (Abstract Window Toolkit) is the older, platform-dependent GUI, while Swing is a newer, platform-independent GUI. Both AWT and Swing components are stored in containers called frames. However, swing frames are independent of the native operating system’s frames, whereas AWT frames are not. This means that swing frames can be displayed on any operating system, whereas AWT frames can only be displayed on the operating system for which they were designed. Swing also has a number of other advantages over AWT, such as a richer set of components, better support for animation and events, and greater flexibility in terms of layout management. However, AWT components are still used in some applications because they are more efficient than Swing components in terms of memory usage and processing speed.


In conclusion, AWT and Swing are two different frameworks for Java development. AWT is more basic and less functional than Swing, which provides a number of features to make development easier. If you are new to Java programming, we recommend using the Swing framework.
