I would recommend trying python first, since it is the easiest language to learn and use (Plus it's waay easier to do networking in if you want to use a co-processor for openCV).

My next recommendation would be C++. The reason why most people tend to go for java over C is because java tends to be more simplified than C. However because of the WPIlibs libraries it is just as easy to use java as it is to use C. C is easier to use for networking that java (Surprisingly).
