Review comment:
This is a question more from my own interest point of view, as I know
this is not a performance critical piece of code.
These two variables are effectively constants, but they are defined at the
method level. Do you know if Java is smart enough to realise these are
constants and evaluate the expression only once? Compared to defining these as
"private static final" at the class level, will this perform the same or worse?
I will try to answer this myself with a quick benchmark if I get some time.
