is c universal kile java

is c really unviversal like java. is c++ better in making drivers and other programs.

C is not as much universal as java but more than any other languages.
And for device drivers c/c++ are best afaik...

I don't know exactly what you mean by universal, but programs written in C can do much more with your computer than programs written in Java. If they're written carefully they can even be compiled for more platforms, while Java programs can just be compiled once and run out-of-the-box on any platform with a virtual machine.
Device drivers are best written in C (C compiles to much faster, more compact machine code) although since C++ is just C with a few whistles and bells, you can probably write them just as well in C++. Java, however, isn't appropriate for writing drivers. Unless you write some JNI, you're limited to Sun's cross-platform APIs with no special devices.
