Is there a way in Java to use unsigned numbers like in (My)SQL?
For example: I want to use an 8-bit variable (byte) with a range like: 0 … 256; instead of -128 … 127.
No, Java doesn’t have any unsigned primitive types apart from
char(which has values 0-65535, effectively). It’s a pain (particularly forbyte), but that’s the way it is.Usually you either stick with the same size, and overflow into negatives for the “high” numbers, or use the wider type (e.g.
shortforbyte) and cope with the extra memory requirements.
