Actually, based on design of the language, leaving out the interpreter
and vm implementaion design, Java should be faster than C++ (internally
everything is done with pointers, no virtual method tables, no
multiple-inheritence, etc.) but it is not. This is not because of
language design, but rather implementation design.
