Some operations are faster in Java these days, _most_ are functionally equal, and a few special cases (not relevant to most developers), C++ is a better choice. Making the blanket "Java is slow" statement is just factually wrong today. Can we move on from 1992, please?
I'd add to your last statement and say: Write it in the supported platform and verify your assumptions that it is too slow, then see how you can optimize from there on that platform, and then if all that fails, try something custom. http://c2.com/cgi/wiki?PrematureOptimization On Sunday, May 11, 2014 7:40:37 AM UTC-7, Larry Meadors wrote: > > If you're thinking Java is slow on a desktop compared to c++, you're > right - it is. > > But Android doesn't actually run Java. :-| > > You write code using the Java language.
