If you haven’t watched a talk on language stewardship and evolution in a while – I would highly recommend this one.
Brian Goetz, Oracle’s Java Language Architect, makes a brilliant, witty, and passionate case for pragmatic evolution of programming languages and provides compelling reasons why Java not only remains relevant as the top programming language and platform of choice but – even after 20 years – continues to deliver innovation that matters to the entire IT software ecosystem, including 9 million Java developers and those building software with alternate languages on top of the Java runtime.
At JavaOne a few weeks ago, Oracle made available the Java ME 8.1 Developer Preview release for the Freescale FRDM-K64F (“Java ME 8.1 in 190 KB RAM”) and announced the upcoming full release of Java ME Embedded 8.1 (press release).
On Monday this week, we followed up as promised and posted the General Availability (GA) releases of Oracle Java ME 8.1 and the Oracle ME SDK 8.1.
Oracle Java ME Embedded 8.1 and ME SDK 8.1 New Features and Enhancements
- Support for ARM Cortex-M3/-M4 micro-controllers
- Updated Raspberry Pi support
- Updated Developer Preview on FRDM-K64 with mbed
- Improved support for two additional Qualcomm Gobi device families
- New communication, security, and networking features
- New support for Eclipse IDE, including major update of the Eclipse MTJ plugin
- Developer improvements: Tooling over USB, heap analysis, faster communication
- A number of smaller enhancements and fixes
Java 8: Truly Scalable
With this release, Java ME 8 now fully lives up to its design promise of delivering a feature-rich Java 8 platform that scales from powerful embedded systems all the way down to resource-constrained singe-chip micro-controllers with as little as 128 KB of RAM.
Developers can now rely on a consistent, standards-based programming model and platform that allows true code reuse from large to small solutions … in most cases the same, unmodified application binary will run across the entire range of target devices – irrespective of the underlying hardware and software differences. This means faster time-to-market, improved security and flexibility, and the ability to deliver more product value, faster.
No other embedded software technology can do that today.
