This question is for all experienced software & quant finance guys:
In the industry, how many companies use Java for Numerical analysis as compared to C++ & other languages (ratio or percentage would be great)?

We use Java for a lot of the Math as well as prop libraries in C++ but I can't comment of ratios or anything like it. I will be misleading you.
