Could this be advice based on C++ experience rather than Java? In C++
I understand the two behave rather differently even if the result of
the calculation is often the same.

In particular "x++" may have some slight overhead issues in C++ in
that the compiler will need to keep a temporary copy of the original
state of "x" until the entire statement has been evaluated. I have
seen people advocate the use of "++x" in its stead for this reason,
when the difference otherwise doesn't matter.

In Java the only issue I can see is if you don't understand the
difference between ++x and x++, in which case you may want to use x += 1 
until you have read up some more on the ++ operator.

Cheers,
