it isn't OK to just use a signed integer to store an unsigned value.

   Absolutely, must have come from an assembler background, where the use of signed branches and arithmetic, can get you into serious trouble.
The standard C library, of course, tends to use signed variables for
everything, a gross error that has never been fixed...

At least the C people can define an unsigned variable.
Java does not have unsigned data types at all. OK - higher level
language and all that. But still a PITA.
