Why AWT is Platform Independent?
The Java AWT utilizes the native platform subroutine to create API components such as TextField, CheckBox, and buttons. This results in a different visual format for these components on different platforms such as Windows, MAC OS, and Unix. The reason for this is that each platform has a distinct view of its native components. AWT directly calls this native subroutine to create the components, resulting in an AWT application resembling a Windows application on Windows OS, and a Mac application on the MAC OS. In simpler terms, the AWT application’s appearance adapts to the platform it is running on.
AWT is platform independent even after the AWT components are platform dependent because of the points mentioned below:
1. JVM (Java Virtual Machine):
As Java Virtual Machine is platform dependent
2. Abstract APIs:
AWT provides an abstract layer for GUI. Java applications interact with AWT through Abstract API which are platform independent. Abstract API allows Java to isolate platform-specific details, making code portable across different systems.
3. Platform-Independent Libraries:
The Libraries of AWT are written in Java which they are totally platform-independent. Because of this, it ensures that AWT functionality remains consistent across different environments.
Java AWT Tutorial
Java AWT or Abstract Window Toolkit is an API used for developing GUI(Graphic User Interfaces) or Window-Based Applications in Java. Java AWT is part of the Java Foundation Classes (JFC) that provides a way to build platform-independent graphical applications.
In this AWT tutorial, you will learn the basics of the AWT, including how to create windows, buttons, labels, and text fields. We will also learn how to add event listeners to components so that they can respond to user input.
By the end of this tutorial, you will have a good understanding of the AWT and be able to create simple GUIs in Java.
