AWT PackagesĪWT is huge! It consists of 12 packages of 370 classes (Swing is even bigger, with 18 packages of 737 classes as of JDK 8). I shall start with the AWT before moving into Swing to give you a complete picture of Java Graphics. For advanced 2D graphics programming, read "Java 2D Tutorial". The best online reference for Graphics programming is the "Swing Tutorial". You need to refer to the "JDK API documentation" for the AWT/Swing APIs (under module sktop) while reading this chapter. Furthermore, developers have moved to use technologies such as HTML5 as the basis of webapps. Other than AWT/Swing/JavaFX graphics APIs provided in JDK, other organizations/vendors have also provided graphics APIs that work with Java, such as Eclipse's Standard Widget Toolkit (SWT) (used in Eclipse), Google Web Toolkit (GWT) (used in Android), 3D Graphics API such as Java bindings for OpenGL (JOGL), Java3D, and etc. JavaFX was moved out from the JDK in JDK 11, but still available as a separate module. The latest JavaFX, which was integrated into JDK 8, was meant to replace Swing.JFC has been integrated into core Java since JDK 1.2. JFC consists of Swing, Java2D, Accessibility, Internationalization, and Pluggable Look-and-Feel Support APIs. Swing API, a much more comprehensive set of graphics libraries that enhances the AWT, was introduced as part of Java Foundation Classes (JFC) after the release of JDK 1.1.Most of the AWT UI components have become obsolete and should be replaced by newer Swing UI components. There are current three sets of Java APIs for graphics programming: AWT ( Abstract Windowing Toolkit), Swing and JavaFX. I will describe another important OO concept called nested class (or inner class) in this article. I shall assume that you have a good grasp of OOP, including composition, inheritance, polymorphism, abstract class and interface otherwise, read the earlier articles. However, re-using them are not so difficult, if you follow the API documentation, samples and templates provided. Writing your own graphics classes (and re-inventing the wheels) is mission impossible! These graphics classes, developed by expert programmers, are highly complex and involve many advanced design patterns. In this article, I shall show you how you can reuse the graphics classes provided in JDK for constructing your own Graphical User Interface (GUI) applications. These classes are self-contained and are reusable. ![]() You can create high-level abstract data types called classes to mimic real-life things. As discussed, OOP permits higher level of abstraction than traditional Procedural-Oriented Languages (such as C). ![]() A shared link will be deleted if it has been passive for almost 3 months.So far, we have covered the basic programming constructs (such as variables, data types, decision, loop, array and method) and introduced the important concept of Object-Oriented Programming (OOP). Just click Share Button and it will create a short link, which can be shared through Email, WhatsApp or even through Social Media. You can use this feature to share your Java Code with your teachers, classmates and colleagues. So before you save a project, please create a login Id using a link given at the top right corner of this page. To save a project you will need to create a login Id with us. You can save your Java Project with us so that you can access this project later on. So simply run a program and provide your program input (if any) from the terminal window available in the right side. The latest version of Coding Ground allows to provide program input at run time from the termnial window exactly the same way as you run your program at your own computer. ![]() This development environment provides you the latest version OpenJDK 11.0.17 as of August 2023. The most user friendly and intuitive Online Java Compiler (version OpenJDK 11.0.17) helps you to Edit, Run and Share your Java Code directly from your browser.
