1. Introduction
• New kind of developers
Building a simple media player application in Java takes 100
lines of code but JavaFX Script can do it in 20 or 30.

2.2 Operating System(s)
• JavaFX applications will run on any desktop and browser that runs the
•
Java Runtime Environment and easily integrates with Java ME, opening
up the door to billions of mobile phones and other connected devices!
Independent application platform, built on Java
•
•
•
Android
Windows Mobile
proprietary real-time operating systems
“Java FX is an expressive rich client platform for creating and delivering
rich Internet experiences across all the screens of your life.”

2.5 Performance
• The (unoffical) bubblemark scores are as following:
• JavaFx/Vectors: 20 fps, 50% CPU
• Flash/Flex: 21fps, 83% CPU
• Silverlight/CLR: 40fps, 82% CPU
• Flash/cacheAsBitmap: 64fps, 58% CPU
• Java/Swing (optimized): 163fps, 50% CPU
• Java/PulpCore: 200fps, 50% CPU

2.5 Performance
• The performance of javaFX is rather slow at the moment when
compared to its competitors, but in speed-critical portions off the
program ordinary java code can be used to speed up the program.
Here are some general tips to speed up your javafx code.

Avoid unnecessary bindings
Keep the scenegraph as small as possible
Use simple shapes instead of images
Use small images instead of complex shapes

2.6 Future possibilities
• Sun has reveled their roadmap as following:
̵ 12/04/2008 - JavaFX SDK 1.0 w/ beta Mobile
̵ 02/12/2009- JavaFX w/ final Mobile
̵ JavaOne 09 - JavaFX Next bèta
̵ JavaOne 09 - Java 7 bèta
̵ Before 2010 - final Java FX Next & Java7
• One can only hope that more devices will be supported in the future
