Um, has anyone else pointed out that these two programs don't do the 
same thing?  Unless the C++ implemented by GCC is broken, the C++
program reads a whitespace-delimited string, while the Java program
reads a full line of text.

Just sayin'.  (I agree by the way with most of the other comments 
about there being much better ways to accomplish -- well, whatever it
is you're trying to accomplish, given that the two programs seem to
me to be doing slightly different things.)
