Answer 2

C++ is a low level programming language, you have to compile source before start. Java programs runs in virtual machine so in fact it's much more complicated application, and slower than compiled c or c++ app. The reason why some would choose c/c++ instead of java could be speed, small amount of memory or even the fact, that someone knows only c/c++ :)
There are pros and cons about using particular programing language, as everywhere :)
