In late 2013 Oracle released a Java language development kit (JDK) optimized for the Raspberry Pi's platform..
A short time later the Raspberry Pi Foundation included Oracle’s JDK by default in its Raspbian OS image.
However, running a coder-friendly Java editor, like the BlueJ IDE, on the Raspberry Pi was still a problem.
Even better, this version of BlueJ also includes the Pi4J library for direct access to the Raspberry Pi's hardware.
