Chief Java Architect Mark Reinhold has proposed a four-month extension of the Java 9 schedule, moving the General Availability milestones (GA) to July 2017. He explains that minor enhancements and even strongly-justified proposals to target new JEPs to JDK 9 will be considered, so long as they do not add undue risk to the overall release. As before, however, the main focus should be to use this additional time to stabilize, polish, and fine-tune the features that the...

By Andrew Binstock Welcome to the September/October 2016 issue of Java Magazine, in which we look at how to program devices and develop for the Internet of Things (IoT). Devices tend to have intensely individual programming requirements, and what works on one device might not work at all on another, so we chose to stagger the levels of information in these articles. The first article , by Gastón Hillar, shows the minutiae of setting up a small Intel-based board, how to send...
