7. What the Journalist are Saying
“Java may be seem like it is off the radar screen
these days when it comes to smartphones and
tablets, with platforms such as Apple's iOS and
Google's Android clearly dominating the headlines.
But don't count Java out on newfangled small form-
factor devices”
Paul Krill, Computer World, March 17, 2011

25. Java: The Best Platform for Embedded Applications
All the benefits of the Java language and VM: Decouples software development from hardware
1 machine-independence, cross-platform, multi- 6 development cycle
threading/-core, memory management, security, ... Fully OO & highly productive language, APIs,
7 runtime, and tools allow rapid development and
2 Proven, robust, secure, and highly performant
deployment
platform, deployed in a vast range of environments
Leverage huge Java developer base and
3 Isolates your apps from language and platform 8
ecosystem (expertise, existing code)
variations (e.g. C/C++, kernel, libc differences)
9 Easily create end-to-end solutions integrated with
4 Support for key embedded features (low footprint, Java back-end services
power management., low latency, etc)
Scalable to build solutions from constrained
Most popular embedded processors supported, 10 devices to server-class systems
