Thank you for contacting us.
Below you’ll find the answers to your questions:
The Curie module can be programmed in C++; it can’t be programmed in Java. This applies for any software tool you plan to develop, whether if it’s the Intel System Studio for Microcontrollers or the Arduino IDE.
Currently, there aren’t any plans to implement Java to be used in the Curie. The Edison module is a different platform, and has a different development resources.
Let me know if this answers your questions.
