I didn't necessarily mean it as advice, just to point out that cpp is a tool
that can be used for the job, if necessary.  A bit like using a sledgehammer to
fix a radiator (you'll probably break the radiator), but a tool nonetheless. 
But I think the person who asked the original question was sophisticated enough
about C to know this.  

Also, it's worth mentioning that a preprocessor is useful for more than
conditional compilation, and sometimes there are dirty shortcuts where it can be
usful (e.g., code generation), which is where #include and #define have their
uses.  But alas, I agree.  A preprocessor has no place in Java.
