New Java Champion Pratik Patel

Welcome New Java Champion Pratik Patel

Pratik Patel is a long time Java expert, advocate and community organizer. While working as a graduate student at the University of North Carolina’s SunSITE research lab (which was sponsored by Sun Microsystems), he learned about Java and was immediately hooked by the potential of the platform and the language. That year, in 1996, he co-authored the 2nd book on Java. The following year, he wrote the first book on enterprise Java. He went on to implement large-scale Java based systems in investment banking, health-care and telco in various places in the world including New York, London, and Hong Kong.

Starting in 2005, Pratik became involved with the Atlanta Java User’s Group (AJUG), and later became a board member. His work in bringing the world’s experts on Java technology to Atlanta have helped make DevNexus one of the largest community run Java centric conferences in the world. Around the same time, he started to share his deep knowledge of Java and the JVM to developers in the USA and around the world. He is a frequent speaker at the No Fluff Just Stuff tour and other Java-centric conferences. He also is the primary organizer of DevNexusJr, a venture that is part of AJUG to bring the joy of programming to the next generation of developers. Follow him at @prpatel

JavaFX Applications Across Devises

Using the new Gluon Mobile framework and some hardware from Adafruit, Gerrit Grunwald describes how to create a mobile/desktop application that can be used to control a mood light that can be turned on and off, set to a particular color, or set to a color cycling mode. His goal in the article "In the Mood: Build Your Own Mood Light and Control It with Java" is to show how easy it is to create a mobile app based on JavaFX.

The Gluon Mobile framework provides methods for achieving platform-dependent settings, which is critical when building an app for different platforms--such as mobile, embedded, and desktop devices--because the UI design is often totally different on different platforms. And, if you are building an Android app, Grundwald points out another advantage of the Gluon Mobile framework: even though Android is not capable of running Java 8, you can use Java 8 in your source code because Gluon Mobile uses retrolambda, which makes it possible to use Java 8 features (except streams) on Java 7.

Grundwald's mood light can be hooked up to the internet and controlled remotely from different devices, such as a mobile phone and a desktop computer. And, if you don't think you need a mood light, he points out another use: you can use it as a build-server status light or for other purposes.

To see how using JavaFX on mobile devices can be a real alternative to native applications--not for all use cases, but at least for some--read the article.
